No cure for the condition as such exists. A number of treatments may provide partial relief:

- Botox injections may temporarily disable the muscle and provide relief for 3-4 months per injection

- Muscle relaxants

- Lorazepam (Ativan), diazepam (Valium) and other benzodiazepines relax the smooth muscle in the throat, slowing or halting contractions. In some people, benzodiazepines may have addictive properties.

- Stress reduction

- High stress levels make these spasms more noticeable

- It is advisable to take note of when your symptoms are at their worst

- Warm fluids

- Hot fluids may be helpful for some people with cricopharyngeal spasm (or other esophageal disorders)

Nutcracker esophagus is a benign, nonprogressive condition, meaning it is not associated with significant complications. Patients are usually reassured by their physicians that the disease is unlikely to worsen. However, the symptoms of chest pain and dysphagia may be severe enough to require treatment with medications, and rarely, surgery.

The initial step of treatment focuses on reducing risk factors. While weight reduction may be useful in reducing symptoms, the role of acid suppression therapy to reduce esophageal reflux is still uncertain. Very cold and very hot beverages may trigger esophageal spasms.

Medical therapy for nutcracker esophagus includes the use of calcium-channel blockers, which relax the lower esophageal sphincter (LES) and palliate the dysphagia symptoms. Diltiazem, a calcium-channel blocker, has been used in randomized control studies with good effect. Nitrate medications, including isosorbide dinitrate, given before meals, may also help relax the LES and improve symptoms. The inexpensive generic combination of belladonna and phenobarbital (Donnatal and other brands) may be taken three times daily as a tablet to prevent attacks or, for patients with only occasional episodes, as an elixir at the onset of symptoms. Phosphodiesterase inhibitors, such as sildenafil, can be given to reduce symptoms, particularly pain, but small trials have not been able to demonstrate clinical improvement. Finally, trazodone, an antidepressant that reduces visceral sensitivity, has also been shown to reduce chest pain symptoms in patients with nutcracker esophagus.

Endoscopic therapy with botulinum toxin, known also as Botox, can also be used to improve dysphagia which stabilizes unintentional weight loss, but the effect has limited effect on other symptoms, including pain, while also being a temporary treatment lasting a few weeks. Finally, pneumatic dilatation of the esophagus, which is an endoscopic technique where a high-pressure balloon is used to stretch the muscles of the LES, can be performed to improve symptoms, but again no clinical improvement is seen in regards to motility.

In patients who have no response to medical or endoscopic therapy, surgery can be performed. A Heller myotomy involves an incision to disrupt the LES and the myenteric plexus that innervates it. The Heller myotomy is used as a final treatment option in patients who do not respond to other therapies.

Both before and after treatment, achalasia patients may need to eat slowly, chew very well, drink plenty of water with meals, and avoid eating near bedtime. Raising the head off the bed or sleeping with a wedge pillow promotes emptying of the esophagus by gravity. After surgery or pneumatic dilatation, proton pump inhibitors are required to prevent reflux damage by inhibiting gastric acid secretion, and foods that can aggravate reflux, including ketchup, citrus, chocolate, alcohol, and caffeine, may need to be avoided.

Drugs that reduce LES pressure are useful. These include calcium channel blockers such as nifedipine and nitrates such as isosorbide dinitrate and nitroglycerin. However, many patients experience unpleasant side effects such as headache and swollen feet, and these drugs often stop helping after several months.

Botulinum toxin (Botox) may be injected into the lower esophageal sphincter to paralyze the muscles holding it shut. As in the case of cosmetic Botox, the effect is only temporary and lasts about 6 months. Botox injections cause scarring in the sphincter which may increase the difficulty of later Heller myotomy. This therapy is recommended only for patients who cannot risk surgery, such as elderly people in poor health. Pneumatic dilatation has a better long term effectiveness than botox.

If small and asymptomatic, no treatment is necessary. Larger, symptomatic cases of Zenker's diverticulum have been traditionally treated by neck surgery to resect the diverticulum and incise the cricopharyngeus muscle. However, in recent times non-surgical endoscopic techniques have gained more importance (as they allow for much faster recovery), and the currently preferred treatment is endoscopic stapling (i.e. diverticulotomy with staples ). This may be performed through a diverticuloscope. Other methods include fibreoptic diverticular repair.

Other non-surgical treatment modalities also exist, such as endoscopic laser, which recent evidence suggests is less effective than stapling.

The patient is generally sent for a GI, pulmonary, or ENT, depending on the suspected underlying cause. Consultations with a speech therapist and registered dietitian nutritionist (RDN) are also needed, as many patients may need dietary modifications such as thickened fluids.

Surgical release involves the two heads of the sternocleidomastoid muscle being dissected free. This surgery can be minimally invasive and done laparoscopically. Usually surgery is performed on those who are over 12 months old. The surgery is for those who do not respond to physical therapy or botulinum toxin injection or have a very fibrotic sternocleidomastoid muscle. After surgery the child will be required to wear a soft neck collar (also called as Callot's cast). There will be an intense physiotherapy program for 3–4 months as well as strengthening exercises for the neck muscles.

Other treatments include:

- Rest and analgesics for acute cases

- Diazepam or other muscle relaxants

- Botulinum toxin

- Encouraging active movements for children 6–8 months of age

- Ultrasound diathermy

Initially, the condition is treated with physical therapies, such as stretching to release tightness, strengthening exercises to improve muscular balance, and handling to stimulate symmetry. A TOT collar is sometimes applied. Early initiation of treatment is very important for full recovery and to decrease chance of relapse.

In some cases Meige's syndrome can be reversed when it is caused by medication. It has been theorized that it is related to cranio-mandibular orthopedic misalignment, a condition that has been shown to cause a number of other movement disorders (Parkinon's, tourettes, and torticollis). This theory is supported by the fact that the trigeminal nerve is sensory for blink reflex, and becomes hypertonic with craniomandibular dysfunction. Palliative treatments are available, such as botulinum toxin injections.

There are two sphincters in the oesophagus. They are normally contracted and they relax when one swallows so that food can pass through them going to the stomach. They then squeeze closed again to prevent regurgitation of the stomach contents. If this normal contraction becomes a spasm, these symptoms begin.

Treatment of hypokalemic periodic paralysis focuses on preventing further attacks and relieving acute symptoms. Avoiding carbohydrate-rich meals, strenuous exercise and other identified triggers, and taking acetazolamide (Diamox®) or another carbonic anhydrase inhibitor, may help prevent attacks of weakness. Some patients also take potassium-sparing diuretics such as spironolactone (Aldactone®) to help maintain potassium levels.

Paralysis attacks can be managed by drinking one of various potassium salts dissolved in water (debate exists over which, if any one in particular, is best used, but potassium chloride and bicarbonate are common). Rapidly absorbed boluses of liquid potassium are generally needed to abort an attack, but some patients also find positive maintenance results with time-released potassium tablets. IV potassium is seldom justified unless the patient is unable to swallow. Daily potassium dosage may need to be much higher than for potassium replacement from simple hypokalemia: 100-150 mEqs of potassium is often needed to manage daily fluctuations in muscle strength and function.

Although treatment for tennis elbow prior 2010 was unknown because the etiology remained unclear, tests confirmed that the cause was an imbalance with the agonist-antagonist functional relationship. Treatment now includes anti-inflammatory medicines, rest, equipment check, physical therapy, braces, steroid injections, shock wave therapy and if symptoms persist after 6 to 12 months, doctors may recommend surgery.

Although treatment varies depending on how bad eye alignment is and also the underlying causes of strabismus. Treatment for strabismus may include orthoptics a term used for eye muscle training, this treatment can be provided by orthoptists and also optometrists. Other treatment may include wearing eye patches aimed at strengthening the weaker eye while inhibiting the stronger eye, an alternative to eye patches is the use of an opaque lens, other treatments may include eye drops to temporarily inhibit the stronger eye and at any age eye muscle surgery can be done to correct the muscular balance of the ocular muscles.

Although the cause of scoliosis can sometimes remain unknown (idiopathic scoliosis) there is treatment available that targets at strengthening the back muscles, for milder cases usually do not require medical attention, more severe cases require either muscle strengthening exercises aimed at the back muscles and even special back braces or surgery can be recommended if the case is extreme. Studies have shown that treatment with a special back brace among children ranging from 10–16 years can be successful and using this method of muscle training scoliosis can be cured with non-surgical treatment.

It is not clear exactly what causes esophageal spasms. Sometimes esophageal spasms start when someone eats hot or cold foods or drinks. However, they can also occur with eating or drinking. The increased release of acetylcholine may also be a factor, but the triggering event is not known.

In the great majority of cases, sufferers experience no life-altering discomfort, and no treatment is required. If there is pain or discomfort, 3 or 4 sips of room temperature water will usually relieve the pain. Symptomatic patients should elevate the head of their beds and avoid lying down directly after meals. If the condition has been brought on by stress, stress reduction techniques may be prescribed, or if overweight, weight loss may be indicated. Antisecretory drugs like proton pump inhibitors and H receptor blockers can be used to reduce acid secretion. Medications that reduce the lower esophageal sphincter (LES) pressure should be avoided.

However, in some unusual instances, as when the hiatal hernia is unusually large, or is of the paraesophageal type, it may cause esophageal stricture or severe discomfort. About 5% of hiatus hernias are paraesophageal. If symptoms from such a hernia are severe for example if chronic acid reflux threatens to severely injure the esophagus or is causing Barrett's esophagus, surgery is sometimes recommended. However surgery has its own risks including death and disability, so that even for large or paraesophageal hernias, watchful waiting may on balance be safer and cause fewer problems than surgery. Complications from surgical procedures to correct a hiatus hernia may include gas bloat syndrome, dysphagia (trouble swallowing), dumping syndrome, excessive scarring, and rarely, achalasia. Surgical procedures sometimes fail over time, requiring a second surgery to make repairs.

One surgical procedure used is called Nissen fundoplication. In fundoplication, the gastric fundus (upper part) of the stomach is wrapped, or plicated, around the inferior part of the esophagus, preventing herniation of the stomach through the hiatus in the diaphragm and the reflux of gastric acid. The procedure is now commonly performed laparoscopically. With proper patient selection, laparoscopic fundoplication recent studies have indicated relatively low complication rates, quick recovery, and relatively good long term results.

Baclofen, diazepam and dantrolene remain the three most commonly used pharmacologic agents in the treatment of spastic hypertonia. Baclofen is generally the drug of choice for spinal cord types of spasticity, while sodium dantrolene is the only agent which acts directly on muscle tissue. Tizanidine is also available. Phenytoin with chlorpromazine may be potentially useful if sedation does not limit their use. Ketazolam, not yet available in the United States, may be a significant addition to the pharmacologic armamentarium. Intrathecal administration of antispastic medications allows for high concentrations of drug near the site of action, which limits side effects.

With the exception of a few case reports describing survival without surgery, the mortality of untreated Boerhaave syndrome is nearly 100%. Its treatment includes immediate antibiotic therapy to prevent mediastinitis and sepsis, surgical repair of the perforation, and if there is significant fluid loss it should be replaced with IV fluid therapy since oral rehydration is not possible. Even with early surgical intervention (within 24 hours) the risk of death is 25%.

Treatment for acquired noninflammatory myopathy is directed towards resolution of the underlying condition, pain management, and muscle rehabilitation.

Drug induced ANIMs can be reversed or improved by tapering off of the drugs and finding alternative care. Hyperthyroidism induced ANIM can be treated through anti-thyroid drugs, surgery and not eating foods high in Iodine such as kelp. Treatment of the hyperthyroidism results in complete recovery of the myopathy. ANIM caused by vitamin D deficiency can easily be resolved by taking vitamin supplements and increasing one's exposure to direct sunlight.

Pain can be managed through massaging affected areas and the use of nonsteroidal anti-inflammatory drugs (NSAIDs).

Exercise, physical therapy, and occupational therapy can be used to rehabilitate affected muscle areas and resist the atrophy process.

As with all myopathies, the use of walkers, canes, and braces can assist with the mobility of the afflicted individual.

Sudden cessation of high-dose corticosteroids, opioids, barbiturates, benzodiazepines, caffeine or alcohol can induce myalgia in many respects.

Therapeutic interventions are best individualized to particular patients.

Basic principles of treatment for hypertonia are to avoid noxious stimuli and provide frequent range of motion exercise.

Esophageal spasm is rare. Often, symptoms that may suggest esophageal spasm are the result of another condition such as gastroesophageal reflux disease (GERD) or achalasia. The symptoms can also include dysphagia, regurgitation, noncardiac chest pain, heartburn, globus pharyngis (which is a feeling that something is stuck in the throat) or a dry cough.

Treatment includes supportive care with analgesics and anti-inflammatory agents. Exercise should be limited as it increases pain and extends the area of infarction. Symptoms usually resolve in weeks to months, but fifty percent of sufferers will experience relapse in either leg.

There are several options of treatment when iatrogenic (i.e., caused by the surgeon) spinal accessory nerve damage is noted during surgery. For example, during a functional neck dissection that injures the spinal accessory nerve, injury prompts the surgeon to cautiously preserve branches of C2, C3, and C4 spinal nerves that provide supplemental innervation to the trapezius muscle. Alternatively, or in addition to intraoperative procedures, postoperative procedures can also help in recovering the function of a damaged spinal accessory nerve. For example, the Eden-Lange procedure, in which remaining functional shoulder muscles are surgically repositioned, may be useful for treating trapezius muscle palsy.

Treatment of muscle dysmorphia can be stymied by a patient's unawareness that the preoccupation is disordered or by avoidance of treatment. Scientific research on treatment of muscle dysmorphia is limited, the evidence largely in case reports and anecdotes, and no specific protocols have been validated. Still, evidence supports the efficacy of family-based therapy, cognitive behavioural therapy, and pharmacotherapy with selective serotonin reuptake inhibitors. Also limited is research on prognosis of the untreated.

The prognosis tends to be good for patients with MG. It is often best not to treat mild cases of MG. Management necessitates avoidance of medications that can worsen neuromuscular transmission, such as aminoglycoside antibiotics, quinolone antibiotics, beta-blockers, chloroquine, anti-arrhythmics, calcium channel blockers, some anticonvulsants and intravenous iodinated contrast should be avoided.

MG is characteristically variable in course, with the frequency of diplopia and ptosis affected by environmental, emotional and physical factors such as bright sunlight, stress, viral illness, menstruation, pregnancy, etc. Spontaneous remission can occur in any patient and remain for years. In a study of the natural history of generalized MG among 168 patients (with an average follow-up of 12 years), 14% experienced complete remission.

Patients with mild-to-moderate ocular myasthenia are usually treated initially with oral anticholinesterase agents, Mestinon (pyridostigmine) being the most commonly employed. There have not been any randomized clinical trials conducted with these agents, and this treatment is often unsuccessful, particularly in resolving diplopia. Immunosuppressive therapy is then started and the agent of choice is usually prednisone. In a small controlled study this drug demonstrated greater efficacy than pyridostigmine. Steroid therapy is controversial, but in another study the results suggested that prednisone does decrease progression to generalized MG. There is no single recommended dosing regimen in light of the side effects commonly associated with chronic corticosteroid therapy, and the difficulty in weaning patients from steroids without exacerbation of symptoms. Response to prednisone therapy is variable.

Additionally, MG patients should be examined for thymomas, and if found, should undergo surgery to address this condition. A prophylactic thymectomy is controversial, but has been shown to be helpful in young MG patients with acute disease within 3 years of disease onset, in patients with enlarged thymus glands and for whom surgery is low-risk, and patients with generalized MG who are unresponsive to medical treatment.

The symptoms of ocular MG can also be addressed by non-medicinal means. Ptosis can be corrected with placement of crutches on eyeglasses and with ptosis tape to elevate eyelid droop. Diplopia can be addressed by occlusion with eye patching, frosted lens, occluding contact lens, or by simply placing opaque tape over a portion of eyeglasses. Also, plastic prisms (Fresnel prisms) can be attached to eyeglasses of a diplopic patient, allowing for alignment of vision from both eyes in the affected direction, but are often problematic if the degree of muscle weakness, and therefore ocular misalignment, fluctuates frequently.
