Cilostazol or pentoxifylline can improve symptoms in some. Cilostazol may improve walking distance for people who experience claudication due to peripheral artery disease, but there is no strong evidence to suggest that it improves the quality of life, decreases mortality, or decreases the risk of cardiovascular events.

Treatment with other drugs or vitamins are unsupported by clinical evidence, "but trials evaluating the effect of folate and vitamin B-12 on hyperhomocysteinemia, a putative vascular risk factor, are near completion".

After a trial of the best medical treatment outline above, if symptoms persist, patients may be referred to a vascular or endovascular surgeon. The benefit of revascularization is thought to correspond to the severity of ischemia and the presence of other risk factors for limb loss such as wound and infection severity.

- Angioplasty (PTA, or percutaneous transluminal angioplasty) can be done on solitary lesions in large arteries, such as the femoral artery, but angioplasty may not have sustained benefits. Patency rates following angioplasty are highest for iliac arteries, and decrease with arteries towards the toes. Other criteria that affect outcome following revascularization are length of lesion, and number of lesions. There does not appear to be long term advantages or sustained benefit to placing a stent following angioplasty in order to hold the narrowing of the superficial femoral artery open.

- Atherectomy, in which the plaque is scraped off of the inside of the vessel wall (albeit with no better results than angioplasty).

- Vascular bypass grafting can be performed to circumvent a diseased area of the arterial vasculature. The great saphenous vein is used as a conduit if available, although artificial (Gore-Tex or PTFE) material is often used for long grafts when adequate venous conduit is unavailable.

- When gangrene has set in, amputation is required to prevent infected tissues from causing sepsis a life-threatening illness.

- Thrombolysis and thrombectomy are used in cases of arterial thrombosis or embolism.

Early treatment is essential to keep the affected limb viable. The treatment options include injection of an anticoagulant, thrombolysis, embolectomy, surgical revascularisation, or amputation. Anticoagulant therapy is initiated to prevent further enlargement of the thrombus. Continuous IV unfractionated heparin has been the traditional agent of choice.

If the condition of the ischemic limb is stabilized with anticoagulation, recently formed emboli may be treated with catheter-directed thrombolysis using intraarterial infusion of a thrombolytic agent (e.g., recombinant tissue plasminogen activator (tPA), streptokinase, or urokinase). A percutaneous catheter inserted into the femoral artery and threaded to the site of the clot is used to infuse the drug. Unlike anticoagulants, thrombolytic agents work directly to resolve the clot over a period of 24 to 48 hours.

Direct arteriotomy may be necessary to remove the clot. Surgical revascularization may be used in the setting of trauma (e.g., laceration of the artery). Amputation is reserved for cases where limb salvage is not possible. If the patient continues to have a risk of further embolization from some persistent source, such as chronic atrial fibrillation, treatment includes long-term oral anticoagulation to prevent further acute arterial ischemic episodes.

Decrease in body temperature reduces the aerobic metabolic rate of the affected cells, reducing the immediate effects of hypoxia. Reduction of body temperature also reduces the inflammation response and reperfusion injury. For frostbite injuries, limiting thawing and warming of tissues until warmer temperatures can be sustained may reduce reperfusion injury.

The Infarct Combat Project (ICP) is an international nonprofit organization founded in 1998 to fight ischemic heart diseases through education and research.

These ulcers are difficult to heal by basic wound care and require advanced therapy, such as hyperbaric oxygen therapy or bioengineered skin substitutes. If not taken care of in time, there are very high chances that these may become infected and eventually may have to be amputated. Individuals with history of previous ulcerations are 36 times more likely to develop another ulcer.

The prevalence of arterial insufficiency ulcers among people with Diabetes is high due to decreased blood flow caused by the thinning of arteries and the lack of sensation due to diabetic neuropathy. Prevention is the first step in avoiding the development of an arterial insufficiency ulcer. These steps could include annual podiatry check ups that include, "assessment of skin, checking of pedal pulses (assessing for blood flow) and assessing physical sensation".

The management of arterial insufficiency ulcers depends on the severity of the underlying arterial insufficiency. The affected region can sometimes be revascularized via vascular bypass or angioplasty. If infection is present, appropriate antibiotics are prescribed. When proper blood flow is established, debridement is performed. If the wound is plantar (on walking surface of foot), patient is advised to give rest to foot to avoid enlargement of the ulcer. Proper glycemic control in diabetics is important. Smoking should be avoided to aid wound healing.

Treatment of diabetic foot can be challenging and prolonged; it may include orthopaedic appliances, antimicrobial drugs and topical dressings.

Most diabetic foot infections (DFIs) require treatment with systemic antibiotics. The choice of the initial antibiotic treatment depends on several factors such as the severity of the infection, whether the patient has received another antibiotic treatment for it, or whether the infection has been caused by a micro-organism that is known to be resistant to usual antibiotics (e.g. MRSA). The objective of antibiotic therapy is to stop the infection and ensure it does not spread.

It is unclear whether any particular antibiotic is better than any other for curing infection or avoiding amputation. One trial suggested that ertapenem with or without vancomycin is more effective than tigecycline for resolving DFIs. It is also generally unclear whether different antibiotics are associated with more or fewer adverse effects.

It is recommended however that the antibiotics used for treatment of diabetic foot ulcers should be used after deep tissue culture of the wound. Tissue culture and not pus swab culture should be done. Antibiotics should be used at correct doses in order to prevent the emergence of drug resistance.

Prevention of diabetic foot may include optimising metabolic control (regulating glucose levels); identification and screening of people at high risk for diabetic foot ulceration; and patient education in order to promote foot self-examination and foot care knowledge. Patients would be taught routinely to inspect their feet for hyperkeratosis, fungal infection, skin lesions and foot deformities. Control of footwear is also important as repeated trauma from tight shoes can be a triggering factor. There is however only limited evidence that patient education has a long-term impact as a preventative measure.

"Of all methods proposed to prevent diabetic foot ulcers, only foot temperature-guided avoidance therapy was found beneficial in RCTs" according to a meta-analysis.

Treatment depends on the type of amyloidosis that is present. Treatment with high dose melphalan, a chemotherapy agent, followed by stem cell transplantation has showed promise in early studies and is recommended for stage I and II AL amyloidosis. However, only 20–25% of people are eligible for stem cell transplant. Chemotherapy and steroids, with melphalan plus dexamethasone, is mainstay treatment in AL people not eligible for transplant.

In AA, symptoms may improve if the underlying condition is treated; eprodisate has been shown to slow renal impairment by inhibiting polymerization of amyloid fibrils.

In ATTR, liver transplant is a curative therapy because mutated transthyretin which forms amyloids is produced in the liver.

People affected by amyloidosis are supported by multiple organizations, including the Amyloidosis Foundation, Amyloidosis Support Groups Inc., and Amyloidosis Australia, Inc.

Manual therapy and exercise have better efficacy in the long term than electrophysical agents and exercise for function, but not for pain. Manual therapy and exercise are preferably focused at stretching the plantar fascia.

Corticosteroid injections can be effective for temporary relief from symptoms while a person develops a long-term strategy that fits their lifestyle. This form of treatment is thought to reduce discomfort in those with CTS due to its ability to decrease median nerve swelling. The use of ultrasound while performing the injection is more expensive but leads to faster resolution of CTS symptoms. The injections are done under local anesthesia. This treatment is not appropriate for extended periods, however. In general, local steroid injections are only used until more definitive treatment options can be used. Corticosteroid injections do not appear to be very effective for slowing disease progression.

The main treatment for obesity consists of dieting and physical exercise. Diet programs may produce weight loss over the short term, but maintaining this weight loss is frequently difficult and often requires making exercise and a lower food energy diet a permanent part of a person's lifestyle.

In the short-term low carbohydrate diets appear better than low fat diets for weight loss. In the long term; however, all types of low-carbohydrate and low-fat diets appear equally beneficial. A 2014 review found that the heart disease and diabetes risks associated with different diets appear to be similar. Promotion of the Mediterranean diets among the obese may lower the risk of heart disease. Decreased intake of sweet drinks is also related to weight-loss. Success rates of long-term weight loss maintenance with lifestyle changes are low, ranging from 2–20%. Dietary and lifestyle changes are effective in limiting excessive weight gain in pregnancy and improve outcomes for both the mother and the child. Intensive behavioral counseling is recommended in those who are both obese and have other risk factors for heart disease.

Five medications have evidence for long-term use orlistat, lorcaserin, liraglutide, phentermine–topiramate, and naltrexone–bupropion. They result in weight loss after one year ranged from 3.0 to 6.7 kg over placebo. Orlistat, liraglutide, and naltrexone–bupropion are available in both the United States and Europe, whereas lorcaserin and phentermine–topiramate are available only in the United States. European regulatory authorities rejected the latter two drugs in part because of associations of heart valve problems with lorcaserin and more general heart and blood vessel problems with phentermine–topiramate. Orlistat use is associated with high rates of gastrointestinal side effects and concerns have been raised about negative effects on the kidneys. There is no information on how these drugs affect longer-term complications of obesity such as cardiovascular disease or death.

The most effective treatment for obesity is bariatric surgery. The types of procedures include laparoscopic adjustable gastric banding, Roux-en-Y gastric bypass, vertical-sleeve gastrectomy, and biliopancreatic diversion. Surgery for severe obesity is associated with long-term weight loss, improvement in obesity related conditions, and decreased overall mortality. One study found a weight loss of between 14% and 25% (depending on the type of procedure performed) at 10 years, and a 29% reduction in all cause mortality when compared to standard weight loss measures. Complications occur in about 17% of cases and reoperation is needed in 7% of cases. Due to its cost and risks, researchers are searching for other effective yet less invasive treatments including devices that occupy space in the stomach.

Orthotics and corticosteroid injections are widely used conservative treatments for Morton’s neuroma. In addition to traditional orthotic arch supports, a small foam or fabric pad may be positioned under the space between the two affected metatarsals, immediately behind the bone ends. This pad helps to splay the metatarsal bones and create more space for the nerve so as to relieve pressure and irritation. It may however also elicit mild uncomfortable sensations of its own, such as the feeling of having an awkward object under one's foot. Corticosteroid injections can relieve inflammation in some patients and help to end the symptoms. For some patients, however, the inflammation and pain recur after some weeks or months, and corticosteroids can only be used a limited number of times because they cause progressive degeneration of ligamentous and tendinous tissues.

Sclerosing alcohol injections are an increasingly available treatment alternative if the above management approaches fail. Dilute alcohol (4%) is injected directly into the area of the neuroma, causing toxicity to the fibrous nerve tissue. Frequently, treatment must be performed 2–4 times, with 1–3 weeks between interventions. A 60–80% success rate has been achieved in clinical studies, equal to or exceeding the success rate for surgical neurectomy with fewer risks and less significant recovery. If done with more concentrated alcohol under ultrasound guidance, the success rate is considerably higher and fewer repeat procedures are needed.

Radio Frequency Ablation is also used in the treatment of Morton's Neuroma The outcomes appear to be equally or more reliable than alcohol injections especially if the procedure is done under ultrasound guidance.

If such interventions fail, patients are commonly offered surgery known as neurectomy, which involves removing the affected piece of nerve tissue. Postoperative scar tissue formation (known as stump neuroma) can occur in approximately 20%-30% of cases, causing a return of neuroma symptoms. Neurectomy can be performed using one of two general methods. Making the incision from the dorsal side (the top of the foot) is the more common method but requires cutting the deep transverse metatarsal ligament that connects the 3rd and 4th metatarsals in order to access the nerve beneath it. This results in exaggerated postoperative splaying of the 3rd and 4th digits (toes) due to the loss of the supporting ligamentous structure. This has aesthetic concerns for some patients and possible though unquantified long-term implications for foot structure and health. Alternatively, making the incision from the ventral side (the sole of the foot) allows more direct access to the affected nerve without cutting other structures. However, this approach requires a greater post-operative recovery time where the patient must avoid weight bearing on the affected foot because the ventral aspect of the foot is more highly enervated and impacted by pressure when standing. It also has an increased risk that scar tissue will form in a location that causes ongoing pain.

Cryogenic neuroablation is a lesser known alternative to neurectomy surgery. Cryogenic neuroablation (also known as cryo injection therapy, cryoneurolysis, cryosurgery or cryoablation) is a term that is used to describe the destruction of axons to prevent them from carrying painful impulses. This is accomplished by making a small incision (~3 mm) and inserting a cryoneedle that applies extremely low temperatures of between −50 °C to −70 °C to the nerve/neuroma. This results in degeneration of the intracellular elements, axons, and myelin sheath (which houses the neuroma) with wallerian degeneration. The epineurium and perineurium remain intact, thus preventing the formation of stump neuroma. The preservation of these structures differentiates cryogenic neuroablation from surgical excision and neurolytic agents such as alcohol. An initial study showed that cryo neuroablation is initially equal in effectiveness to surgery but does not have the risk of stump neuroma formation.

Recently, an increasing number of procedures are being performed at specialist centers which offer a range of procedures to treat Morton's neuroma under ultrasound guidance. Recent studies have shown excellent results for the treatment of Morton's neuroma with ultrasound guided sclerosing alcohol injections, ultrasound guided radiofrequency ablation, and ultrasound guided cryo-ablation.

Generally accepted treatments include: physiotherapy, steroids either orally or injected locally, splinting, and surgical release of the transverse carpal ligament. Limited evidence suggests that gabapentin is no more effective than placebo for CTS treatment. There is insufficient evidence for therapeutic ultrasound, yoga, acupuncture, low level laser therapy, vitamin B6, and exercise. Change in activity may include avoiding activities that worsen symptoms.

The American Academy of Orthopedic Surgeons recommends proceeding conservatively with a course of nonsurgical therapies tried before release surgery is considered. A different treatment should be tried if the current treatment fails to resolve the symptoms within 2 to 7 weeks. Early surgery with carpal tunnel release is indicated where there is evidence of median nerve denervation or a person elects to proceed directly to surgical treatment. Recommendations may differ when carpal tunnel syndrome is found in association with the following conditions: diabetes mellitus, coexistent cervical radiculopathy, hypothyroidism, polyneuropathy, pregnancy, rheumatoid arthritis, and carpal tunnel syndrome in the workplace.

Treatment can include pharmaceutical or surgical means. The drug carbamazepine (Tegretol) has been used successfully. Other drugs used with variable success include gabapentin and, recently, memantine. Successful surgery options include superior oblique tenectomy accompanied by inferior oblique myectomy. However, "Overall, the bulk of the ophthalmic literature would agree with the viewpoint that invasive craniotomy surgical procedures should be justified only by the presence of intractable and absolutely unbearable symptoms."

Samii et al. and Scharwey and Samii described a patient who had superior oblique myokymia for 17 years. The interposition of a Teflon pad between the trochlear nerve and a compressing artery and vein at the nerve's exit from the midbrain led to a remission lasting for a follow-up of 22 months.

The primary treatment of PPID is pergolide, a dopamine agonist that provides suppression to the pars intermedia in place of the dysfunctional hypothalamus. Horses should be reassessed in 30 days following the start of treatment, though evaluation of clinical signs and by baseline diagnostic testing, to ensure the appropriate dose is being prescribed. Results from that test dictate changes in dose. Horses that are responding to treatment should be retested every 6 months, including a test in the autumn when there is a seasonal increase in ACTH, to ensure their ACTH levels are appropriately suppressed during this time. Drug side effects include a transient decrease in appetite, which can be reduced by slowly increasing the dose to therapeutic levels, and by breaking up the daily dose into twice-daily administrations.

Attitude, activity levels, hyperglycemia, and increased drinking and urination are usually improved within 30 days of initiating treatment. Other clinical signs, such as hirsutism, potbellied appearance, muscle wasting, laminitic episodes, and increased predisposition to infection usually take between 30 days and 1 year to improve.

Cyproheptadine may be added to the treatment regime in horses that are inadequately responding to pergolide, but is usually only used in horses with advanced PPID on high doses of pergolide.

The main methods of management in involve exercise and diet change, in addition to treatment of PPID. The primary goal is reduction of weight in an obese animal. Diet changes include limiting pasture access and reducing or eliminating grain. Obese animals are often best maintained on a diet consisting ration balancer and hay, fed at 1.5% body weight and decreased if needed. Feed should be selected based on low non-structural carbohydrate levels. Hay NSC levels may be reduced by soaking it in cold water for 30 minutes.

Exercise is increased in non-laminitic horses. Animals resistant to weight loss, despite diet and exercise changes, can be placed on levothyroxine to increase metabolism. Metformin can also be used to reduce glucose absorption through the intestinal tract.

Ketosis is deliberately induced by use of a ketogenic diet as a medical intervention in cases of intractable epilepsy. Other uses of low-carbohydrate diets remain controversial. Carbohydrate deprivation to the point of ketosis has been argued to have both negative and positive effects on health.

For those whose RLS disrupts or prevents sleep or regular daily activities, medication may be useful. Evidence supports the use of dopamine agonists including: pramipexole, ropinirole, rotigotine, and cabergoline. They reduce symptoms, improve sleep quality and quality of life. Levodopa is also effective. One review found pramipexole to be better than ropinirole.

There are, however, issues with the use of dopamine agonists including augmentation. This is a medical condition where the drug itself causes symptoms to increase in severity and/or occur earlier in the day. Dopamine agonists may also cause rebound when symptoms increase as the drug wears off. In many cases, the longer dopamine agonists have been used the higher the risk of augmentation and rebound as well as the severity of the symptoms. Also, a recent study indicated that dopamine agonists used in restless leg syndrome can lead to an increase in compulsive gambling.

- Gabapentin or pregabalin, a non-dopaminergic treatment for moderate to severe primary RLS

- Opioids are only indicated in severe cases that do not respond to other measures due to their high rate of side effects.

Benzodiazepines, such as diazepam or clonazepam, are not generally recommended, and their effectiveness is unknown. They however are sometimes still used as a second line, as add on agents. Quinine is not recommended due to its risk of serious side effects involving the blood.

Treatment of restless legs syndrome involves identifying the cause of symptoms when possible. The treatment process is designed to reduce symptoms, including decreasing the number of nights with RLS symptoms, the severity of RLS symptoms and nighttime awakenings. Improving the quality of life is another goal in treatment. This means improving overall quality of life, decreasing daytime sleepiness, and improving the quality of sleep. Pharmacologic treatment involves dopamine agonists or gabapentin enacarbil as first line drugs for daily restless legs syndrome, and opioids for treatment of resistant cases. RLS drug therapy is not curative and has side effects such as nausea, dizziness, hallucinations, orthostatic hypotension, or daytime sleep attacks. An algorithm created by Mayo Clinic researchers provides guidance to the treating physician and patient, including non-pharmacological and pharmacological treatments.

Treatment of RLS should not be considered until possible medical causes are ruled out, especially venous disorders. Secondary RLS may be cured if precipitating medical conditions (anemia, venous disorder) are managed effectively. Secondary conditions causing RLS include iron deficiency, varicose veins, and thyroid problems.

Non-specific treatments include:

- Non-steroidal anti-inflammatory drugs (NSAIDs): ibuprofen, naproxen or aspirin

- Heat or ice

- A counter-force brace or "elbow strap" to reduce strain at the elbow epicondyle, to limit pain provocation and to protect against further damage.

Before anesthetics and steroids are used, conservative treatment with an occupational therapist may be attempted. Before therapy can commence, treatment such as the common rest, ice, compression and elevation (R.I.C.E.) will typically be used. This will help to decrease the pain and inflammation; rest will alleviate discomfort because golfer's elbow is an overuse injury. The patient can use a tennis elbow splint for compression. A pad can be placed anteromedially on the proximal forearm. The splint is made in 30–45 degrees of elbow flexion. A daytime elbow pad also may be useful, by limiting additional trauma to the nerve.

Therapy will include a variety of exercises for muscle/tendon reconditioning, starting with stretching and gradual strengthening of the flexor-pronator muscles. Strengthening will slowly begin with isometrics and progresses to eccentric exercises helping to extend the range of motion back to where it once was. After the strengthening exercises, it is common for the patient to ice the area.

Simple analgesic medication has a place, as does more specific treatment with oral anti-inflammatory medications (NSAIDs). These will help control pain and any inflammation. A more invasive treatment is the injection into and around the inflamed and tender area of a long-acting glucocorticoid (steroid) agent. After causing an initial exacerbation of symptoms lasting 24 to 48 hours, this may produce an improvement of the condition in some five to seven days.

The ulnar nerve runs in the groove between the medial humeral epicondyle and the olecranon process of the ulna. It is most important that this nerve should not be damaged accidentally in the process of injecting a golfer's elbow.

If all else fails, epicondylar debridement (a surgery) may be effective. The ulnar nerve may also be decompressed surgically.

If the appropriate remediation steps are taken - rest, ice, and rehabilitative exercise and stretching - recovery may follow. Few patients will need to progress to steroid injection, and less than 10% will require surgical intervention.

Intraocular pressure can be lowered with medication, usually eye drops. Several classes of medications are used to treat glaucoma, with several medications in each class.

Each of these medicines may have local and systemic side effects. Adherence to medication protocol can be confusing and expensive; if side effects occur, the patient must be willing either to tolerate them or to communicate with the treating physician to improve the drug regimen. Initially, glaucoma drops may reasonably be started in either one or in both eyes. Wiping the eye with an absorbent pad after the administration of eye drops may result in fewer adverse effects, like the growth of eyelashes and hyperpigmentation in the eyelid.

Poor compliance with medications and follow-up visits is a major reason for vision loss in glaucoma patients. A 2003 study of patients in an HMO found half failed to fill their prescriptions the first time, and one-fourth failed to refill their prescriptions a second time. Patient education and communication must be ongoing to sustain successful treatment plans for this lifelong disease with no early symptoms.

The possible neuroprotective effects of various topical and systemic medications are also being investigated.

- Prostaglandin analogs, such as latanoprost, bimatoprost and travoprost, increase uveoscleral outflow of aqueous humor. Bimatoprost also increases trabecular outflow.

- Topical beta-adrenergic receptor antagonists, such as timolol, levobunolol, and betaxolol, decrease aqueous humor production by the epithelium of the ciliary body.

- Alpha2-adrenergic agonists, such as brimonidine and apraclonidine, work by a dual mechanism, decreasing aqueous humor production and increasing uveoscleral outflow.

- Less-selective alpha agonists, such as epinephrine, decrease aqueous humor production through vasoconstriction of ciliary body blood vessels, useful only in open-angle glaucoma. Epinephrine's mydriatic effect, however, renders it unsuitable for closed-angle glaucoma due to further narrowing of the uveoscleral outflow (i.e. further closure of trabecular meshwork, which is responsible for absorption of aqueous humor).

- Miotic agents (parasympathomimetics), such as pilocarpine, work by contraction of the ciliary muscle, opening the trabecular meshwork and allowing increased outflow of the aqueous humour. Echothiophate, an acetylcholinesterase inhibitor, is used in chronic glaucoma.

- Carbonic anhydrase inhibitors, such as dorzolamide, brinzolamide, and acetazolamide, lower secretion of aqueous humor by inhibiting carbonic anhydrase in the ciliary body.

Besides the frequent choice to leave the cyst in place, surgical treatments remain the primary elective option for treatment of ganglion cysts. The progression of ganglion surgery worldwide is to use an arthroscopic or mini-opening method. Alternatively, a hypodermic needle may be used to drain the fluid from the cyst (via aspiration) and a corticosteroid may be injected after the cyst is empty; however, if the fluid has thickened, owing to the passage of time, this treatment is not always effective.

There is a recurrence rate of approximately 50% following needle drainage (via aspiration) of ganglion cysts.

One common and traditional method of treatment for a ganglion cyst was to strike the lump with a large and heavy book, causing the cyst to rupture and drain into the surrounding tissues. Historically, a Bible was the largest or only book in any given household, and was often employed for this treatment. This led to the former nickname of "Bible bumps" or "Gideon's disease" for these cysts. This treatment risks injuring the patient.

Complications of treatment may include joint stiffness and scar formation. Recurrence of the lesion is more common following excision of a volar ganglion cyst in the wrist. Incomplete excision that fails to include the stalk or pedicle also may lead to recurrence, as will failing to execute a layered closure of the incision.

Warm sweetened liquids can be given provided the person is alert and can swallow. Many recommend that alcohol and drinks with lots of caffeine be avoided. As most people are moderately dehydrated due to cold-induced diuresis, warmed intravenous fluids to a temperature of are often recommended.
