The opioid antagonist naloxone allowed a woman with congenital insensitivity to pain to experience it for the first time. Similar effects were observed in Na1.7 null mice treated with naloxone. As such, opioid antagonists like naloxone and naltrexone may be effective in treating the condition.

CIPA sufferers have to live an extremely cautious life, incorporating numerous controls as part of their daily routine. Every morning it will be necessary to check for bruises, scratches or other injuries that might have taken place during sleeping hours, as it is very common for CIPA patients to injure themselves unknowingly. Temperature measuring must be done constantly, as well as urination control, by setting alarms or other reminders.

If any kind of accident has been suffered, regardless of its type and severity, CIPA patients must go through a thorough check for compromising injuries.

At young ages, permanent surveillance is vital. A lack of awareness of the extreme dangers this condition represents condemns the infant to a complete lack of tools against risk situations.

There are several other procedures a CIPA patient has to undergo in order to live a safe life. Those mentioned above were extracted from a “Doctor House” episode (Insensitive).

Pharmacological techniques are often continued in conjunction with other treatment options. Doses of pain medications needed often drop substantially when combined with other techniques, but rarely are discontinued completely. Tricyclic antidepressants, such as amitriptyline, and sodium channel blockers, mainly carbamazepine, are often used to relieve chronic pain, and recently have been used in an attempt to reduce phantom pains. Pain relief may also be achieved through use of opioids, ketamine, calcitonin, and lidocaine.

Acute pain is usually managed with medications such as analgesics and anesthetics. Caffeine when added to pain medications such as ibuprofen, may provide some additional benefit. Management of chronic pain, however, is more difficult, and may require the coordinated efforts of a pain management team, which typically includes medical practitioners, clinical pharmacists, clinical psychologists, physiotherapists, occupational therapists, physician assistants, and nurse practitioners.

Sugar (sucrose) when taken by mouth reduces pain in newborn babies undergoing some medical procedures (a lancing of the heel, venipuncture, and intramuscular injections). Sugar does not remove pain from circumcision, and it is unknown if sugar reduces pain for other procedures.

Sugar did not affect pain-related electrical activity in the brains of newborns one second after the heel lance procedure. Sweet liquid by mouth moderately reduces the rate and duration of crying caused by immunization injection in children between one and twelve months of age.

Carbamazepine is at least partly effective at reducing the number or severity of attacks in the majority of PEPD patients. High doses of this drug may be required, perhaps explaining the lack of effect in some individuals. While other anti-epileptic drugs, gabapentin and topiramate, have limited effect in some patients, they have not been shown to be generally effective. Opiate derived analgesics are also largely ineffective, with only sporadic cases of beneficial effect.

Individuals with more social support experience less cancer pain, take less pain medication, report less labor pain and are less likely to use epidural anesthesia during childbirth, or suffer from chest pain after coronary artery bypass surgery.

Suggestion can significantly affect pain intensity. About 35% of people report marked relief after receiving a saline injection they believed to be morphine. This placebo effect is more pronounced in people who are prone to anxiety, and so anxiety reduction may account for some of the effect, but it does not account for all of it. Placebos are more effective for intense pain than mild pain; and they produce progressively weaker effects with repeated administration. It is possible for many with chronic pain to become so absorbed in an activity or entertainment that the pain is no longer felt, or is greatly diminished.

Cognitive behavioral therapy (CBT) has been shown effective for improving quality of life in those with chronic pain but the reduction in suffering is modest, and the CBT method was not shown to have any effect on outcome. Acceptance and Commitment Therapy (ACT) may also effective in the treatment of chronic pain.

A number of meta-analyses have found clinical hypnosis to be effective in controlling pain associated with diagnostic and surgical procedures in both adults and children, as well as pain associated with cancer and childbirth. A 2007 review of 13 studies found evidence for the efficacy of hypnosis in the reduction of chronic pain under some conditions, though the number of patients enrolled in the studies was low, raising issues related to the statistical power to detect group differences, and most lacked credible controls for placebo or expectation. The authors concluded that "although the findings provide support for the general applicability of hypnosis in the treatment of chronic pain, considerably more research will be needed to fully determine the effects of hypnosis for different chronic-pain conditions."

Deep brain stimulation is a surgical technique used to alleviate patients from phantom limb pain. Prior to surgery, patients undergo functional brain imaging techniques such as PET scans and functional MRI to determine an appropriate trajectory of where pain is originating. Surgery is then carried out under local anesthetic, because patient feedback during the operation is needed. In the study conducted by Bittar et al., a radiofrequency electrode with four contact points was placed on the brain. Once the electrode was in place, the contact locations were altered slightly according to where the patient felt the greatest relief from pain. Once the location of maximal relief was determined, the electrode was implanted and secured to the skull. After the primary surgery, a secondary surgery under general anesthesia was conducted. A subcutaneous pulse generator was implanted into a pectoral pocket below the clavicle to stimulate the electrode. It was found that all three patients studied had gained satisfactory pain relief from the deep brain stimulation. Pain had not been completely eliminated, but the intensity had been reduced by over 50% and the burning component had completely vanished.

Testosterone has been used to successfully treat undervirilization in some but not all men with PAIS, despite having supraphysiological levels of testosterone to start with. Treatment options include transdermal gels or patches, oral or injectable testosterone undecanoate, other injectable testosterone esters, testosterone pellets, or buccal testosterone systems. Supraphysiological doses may be required to achieve the desired physiological effect, which may be difficult to achieve using non-injectable testosterone preparations. Exogenous testosterone supplementation in unaffected men can produce various unwanted side effects, including prostatic hypertrophy, polycythemia, gynecomastia, hair loss, acne, and the suppression of the hypothalamic-pituitary-gonadal axis, resulting in the reduction of gonadotropins (i.e., luteinizing hormone and follicle-stimulating hormone) and spermatogenic defect. These effects may not manifest at all in men with AIS, or might only manifest at a much higher concentration of testosterone, depending on the degree of androgen insensitivity. Those undergoing high dose androgen therapy should be monitored for safety and efficacy of treatment, possibly including regular breast and prostate examinations. Some individuals with PAIS have a sufficiently high sperm count to father children; at least one case report has been published that describes fertile men who fit the criteria for grade 2 PAIS (micropenis, penile hypospadias, and gynecomastia). Several publications have indicated that testosterone treatment can correct low sperm counts in men with MAIS. At least one case report has been published that documents the efficacy of treating a low sperm-count with tamoxifen in an individual with PAIS.

Due to its mild presentation, MAIS often goes unnoticed and untreated. Management of MAIS is currently limited to symptomatic management; methods to correct a malfunctioning androgen receptor protein that result from an AR gene mutation are not currently available. Treatment includes surgical correction of mild gynecomastia, minor hypospadias repair, and testosterone supplementation. Supraphysiological doses of testosterone have been shown to correct diminished secondary sexual characteristics in men with MAIS, as well as to reverse infertility due to low sperm count. As is the case with PAIS, men with MAIS will experience side effects from androgen therapy (such as the suppression of the hypothalamic-pituitary-gonadal axis) at a higher dosage than unaffected men. Careful monitoring is required to ensure the safety and efficacy of treatment. Regular breast and prostate examinations may be necessary due to comorbid association with breast and prostate cancers.

Non surgical treatments include steroid injections in the lower back or radiofrequency sensory ablation. Physical therapy interventions are also helpful in early cases and are focused around mobilization, neural stretching, and core strengthening exercises. Surgical intervention is usually a last resort if all conservative methods fail. It can be treated surgically with posterolateral fusion or resection of the transitional articulation.

Most cases of vaginal hypoplasia associated with CAIS can be corrected using non-surgical pressure methods. The elastic nature of vaginal tissue, as demonstrated by its ability to accommodate the differences in size between a tampon, a penis, and a baby's head, make dilation possible even in cases when the vaginal depth is significantly compromised. Treatment compliance is thought to be critical to achieve satisfactory results. Dilation can also be achieved via the Vecchietti procedure, which stretches vaginal tissues into a functional vagina using a traction device that is anchored to the abdominal wall, subperitoneal sutures, and a mold that is placed against the vaginal dimple. Vaginal stretching occurs by increasing the tension on the sutures, which is performed daily. The non-operative pressure dilation method is currently recommended as the first choice, since it is non-invasive, and highly successful. Vaginal dilation should not be performed before puberty.

Although the FD-causing gene has been identified and it seems to have tissue specific expression, there is no definitive treatment at present.

Treatment of FD remains preventative, symptomatic and supportive. FD does not express itself in a consistent manner. The type and severity of symptoms displayed vary among patients and even at different ages on the same patients. So patients should have specialized individual treatment plans. Medications are used to control vomiting, eye dryness, and blood pressure. There are some commonly needed treatments including:

1. Artificial tears: using eye drops containing artificial tear solutions (methylcellulose)

2. Feeding: Maintenance of adequate nutrition, avoidance of aspiration; thickened formula and different shaped nipples are used for baby.

3. Daily chest physiotherapy (nebulization, bronchodilators, and postural drainage): for Chronic lung disease from recurrent aspiration pneumonia

4. Special drug management of autonomic manifestations such as vomiting: intravenous or rectal diazepam (0.2 mg/kg q3h) and rectal chloral hydrate (30 mg/kg q6h)

5. Protecting the child from injury (coping with decreased taste, temperature and pain perception)

6. Combating orthostatic hypotension: hydration, leg exercise, frequent small meals, a high-salt diet, and drugs such as fludrocortisone.

7. Treatment of orthopedic problems (tibial torsion and spinal curvature)

8. Compensating for labile blood pressures

There is no cure for Familial Dysautonomia.

Some have hypothesized that supraphysiological levels of estrogen may reduce the diminished bone mineral density associated with CAIS. Data has been published that suggests affected women who were not compliant with estrogen replacement therapy, or who had a lapse in estrogen replacement, experienced a more significant loss of bone mineral density. Progestin replacement therapy is seldom initiated, due to the absence of a uterus. Androgen replacement has been reported to increase a sense of well-being in gonadectomized women with CAIS, although the mechanism by which this benefit is achieved is not well understood.

There is currently no cure for FD and death occurs in 50% of the affected individuals by age 30. There are only two treatment centers, one at New York University Hospital and one at the Sheba Medical Center in Israel. One is being planned for the San Francisco area.

The survival rate and quality of life have increased since the mid-1980s mostly due to a greater understanding of the most dangerous symptoms. At present, FD patients can be expected to function independently if treatment is begun early and major disabilities avoided.

A major issue has been aspiration pneumonia, where food or regurgitated stomach content would be aspirated into the lungs causing infections. Fundoplications (by preventing regurgitation) and gastrostomy tubes (to provide nonoral nutrition) have reduced the frequency of hospitalization.

Other issues which can be treated include FD crises, scoliosis, and various eye conditions due to limited or no tears.

An FD crisis is the body's loss of control of various autonomic nervous system functions including blood pressure, heart rate, and body temperature. Both short-term and chronic periodic high or low blood pressure have consequences and medication is used to stabilize blood pressure.

Genitoplasty, unlike gender assignment, can be irreversible, and there is no guarantee that adult gender identity will develop as assigned despite surgical intervention. Some aspects of genitoplasty are still being debated; a variety of different opinions have been presented by professionals, self-help groups, and patients over the last few decades. Points of consideration include what conditions justify genitoplasty, the extent and type of genitoplasty that should be employed, when genitoplasty should be performed, and what the goals of genitoplasty should be. Gender assignment itself does not predicate the need for immediate genitoplasty; in some cases, surgical intervention can be delayed to allow the affected child to reach an age and maturity sufficient to have a role in such decisions. Some studies suggest that early surgeries can still produce satisfactory outcomes, while others suggest it to be unlikely. Even surgeries that are planned as one-stage procedures often require further major surgery. Scarring and tissue loss that result from repeated surgical procedures are of particular concern, due to the presumed negative impact on sexual function.

While it is thought that feminizing genitoplasty typically requires fewer surgeries to achieve an acceptable result and results in fewer urologic difficulties, there is no evidence that feminizing surgery results in a better psychosocial outcome. In one study, individuals with grade 3 PAIS who were raised male rated their body image and sexual function similarly to those who were raised female, even though they were more likely to have genitalia that were abnormal in size and appearance; more than half of the male participants had a stretched penile length that was below 2.5 standard deviations of the mean, while only 6% of female participants presented with a short vagina in adulthood, and participating physicians gave a lower cosmetic rating to the surgical results of the men than the women. Both male and female participants cited the appearance of their genitalia as being the greatest contributing factor to their dissatisfaction with their body image. In two larger studies, the common predictor of gender reassignment was stigmatization related to having an intersex condition.

The outcome of masculinizing genitoplasty is dependent on the amount of erectile tissue and the extent of hypospadias. Procedures include correction of penile curvature and chordee, reconstruction of the urethra, hypospadias correction, orchidopexy, and Müllerian remnant removal to prevent infection and pseudo-incontinence. Erectile prosthesis may be inserted in cases of successful neophalloplasty in adulthood, although it has a high morbidity. Additional surgeries may be required to correct postsurgical complications such as stenosis of the anastomosis between the native urethra and the graft, urethral fistulas, and posterior displacement of the balanic meatus. Successful masculinizing genitoplasty performed on individuals with grade 3 PAIS often requires multiple surgeries.

If feminizing genitoplasty is performed in infancy, the result will need to be refined at puberty through additional surgery. Procedures include clitoral reduction / recession, labiaplasty, repair of the common urogenital sinus, vaginoplasty, and vaginal dilation through non-surgical pressure methods. Clitoral reduction / recession surgery carries with it the risk of necrosis as well as the risk of impairing the sexual function of the genitalia, and thus should not be performed for less severe clitoromegaly. Clitoral surgery should be focused on function rather than appearance, with care being taken to spare the erectile function and innervation of the clitoris. If PAIS presents with a common urogenital sinus, the American Academy of Pediatrics currently recommends that surgery to separate the urethra from the vagina be performed at an early age. As is the case for CAIS, vaginal dilation using pressure dilation methods should be attempted before the surgical creation of a neovagina is considered, and neither should be performed before puberty. Complications of feminizing genitoplasty can include vaginal stenosis, meatal stenosis, vaginourethral fistula, female hypospadias, urinary tract injuries, and recurrent clitoromegaly. Successful feminizing genitoplasty performed on individuals with grade 3 PAIS often requires multiple surgeries, although more surgeries are typically required for successful masculinizing genitoplasty in this population.

Many surgical procedures have been developed to create a neovagina, as none of them is ideal. Surgical intervention should be considered only after non-surgical pressure dilation methods have failed to produce a satisfactory result. Neovaginoplasty can be performed using skin grafts, a segment of bowel, ileum, peritoneum, , buccal mucosa, amnion, or dura mater. Success of such methods should be determined by sexual function, and not by vaginal length alone, as has been done in the past. Ileal or cecal segments may be problematic because of a shorter mesentery, which may produce tension on the neovagina, leading to stenosis. The sigmoid neovagina is thought to be self-lubricating, without the excess mucus production associated with segments of small bowel. Vaginoplasty may create scarring at the introitus (the vaginal opening), requiring additional surgery to correct. Vaginal dilators are required postoperatively to prevent vaginal stenosis from scarring. Other complications include bladder and bowel injuries. Yearly exams are required, as neovaginoplasty carries a risk of carcinoma, although carcinoma of the neovagina is uncommon. Neither neovaginoplasty nor vaginal dilation should be performed before puberty.

In order to facilitate sexual intercourse, the main treatments are self-dilation methods (using intra-vaginal cylinders of increasing size) and surgical vaginoplasty to lengthen the vagina.

Self-dilation has a high success rate, estimated at 75%, and is usually the first-line treatment due to low surgical invasiveness. Overall, the complication rates are significantly lower with dilation than with vaginoplasty.

Surgery is indicated when there is inability or reluctance to perform self-dilation, or where it is performed but with failed result. One appropriate surgical variant is the "Vecchietti technique". In this procedure, an olive-shaped pressure device is pressed towards the potential vaginal space by a thread that goes through the skin, behind the urinary bladder and pubic bone and exits the skin in the hypogastrium, where it is attached to a plate that provides counter-traction. Vaginoplasty can also be performed using a skin graft or an intestinal graft. Traction vaginoplasty such as the "Vecchietti technique" seems to have the highest success rates both anatomically (99%) and functionally (96%), whereas skin graft procedures and intestinal procedures have the lowest successful outcomes (83–95%).

After vaginoplasty, available evidence suggests that continued self-dilation is needed to maintain patency in periods of coital inactivity.

Patients with Leydig cell hypoplasia may be treated with hormone replacement therapy (i.e., with androgens), which will result in normal sexual development and the resolution of most symptoms. In the case of 46,XY (genetically "male") individuals who are phenotypically female and/or identify as the female gender, estrogens should be given instead. Surgical correction of the genitals in 46,XY males may be required, and, if necessary, an orchidopexy (relocation of the undescended testes to the scrotum) may be performed as well.

Congenital insensitivity to pain (CIP), also known as congenital analgesia, is one or more rare conditions in which a person cannot feel (and has never felt) physical pain. The conditions described here are separate from the HSAN group of disorders, which have more specific signs and cause. Because feeling physical pain is vital for survival, CIP is an extremely dangerous condition. It is common for people with the condition to die in childhood due to injuries or illnesses going unnoticed. Burn injuries are one of the more common injuries.

Because hormone treatment rarely achieves average size, several surgical techniques similar to phalloplasty for penis enlargement have been devised and performed; but they are not generally considered successful enough to be widely adopted and are rarely performed in childhood.

In extreme cases of micropenis, there is barely any shaft, and the glans appears to sit almost on the pubic skin. From the 1960s until the late 1970s, it was common for sex reassignment and surgery to be recommended. This was especially likely if evidence suggested that response to additional testosterone and pubertal testosterone would be poor. With parental acceptance, the boy would be reassigned and renamed as a girl, and surgery performed to remove the testes and construct an artificial vagina. This was based on the now-questioned idea that gender identity was shaped entirely from socialization, and that a man with a small penis can find no acceptable place in society.

Johns Hopkins Hospital, the center most known for this approach, performed twelve such reassignments from 1960 to 1980, most notably that of David Reimer (whose penis was destroyed by a circumcision accident), overseen by John Money. By the mid-1990s, reassignment was less often offered, and all three premises had been challenged. Former subjects of such surgery, vocal about their dissatisfaction with the adult outcome, played a large part in discouraging this practice. Sexual reassignment is rarely performed today for severe micropenis (although the question of raising the boy as a girl is sometimes still discussed.) (See "History of intersex surgery" for a fuller discussion.)

A treatment option for micropenis is the insertion of a subcutaneous soft silicone implant under the penile skin. The procedure was developed by urologist James J. Elist.

Congenital insensitivity to pain with anhidrosis may be misdiagnosed for leprosy, based on similar symptoms of severe injuries to the hands and feet.

Surgery (orchiopexy) to retrieve the testes and position them in the scrotum is the primary treatment. Occasionally they are unsalvageable if located high in the retroperitoneum. During this surgery, the uterus is usually removed and attempts made to dissect away Müllerian tissue from the vas deferens and epididymis to improve the chance of fertility. If the person has male gender identity himself and the testes cannot be retrieved, testosterone replacement will be usually necessary at puberty should the affected individual choose to pursue medical attention. Lately, laparoscopic hysterectomy is offered to patients as a solution to both improve the chances of fertility and to prevent the occurrences of neoplastic tissue formation.

Hormone replacement therapy with estrogen may be used to treat symptoms of hypoestrogenism in females with the condition. There are currently no known treatments for the infertility caused by the condition in either sex.

Administration of GH has no effect on IGF-1 production, therefore treatment is mainly by biosynthetic IGF-1. IGF-1 must be taken before puberty to be effective.

The drug product Increlex (mecasermin), developed by the company Tercica, now Genentech, was approved by the US Food and Drug Administration in August 2005 for replacing IGF-1 in patients who are deficient.

IPLEX (Mecasermin rinfabate) is composed of recombinant human IGF-1 (rhIGF-1) and its binding protein IGFBP-3. It was approved by the U.S. Food and Drug Administration (FDA) in 2005 for treatment of primary IGF-1 deficiency or GH gene deletion. Side effects from IPLEX are hypoglycemia. IPLEX's manufacturing company, Insmed, after selling its protein production facility, can no longer develop proteins, thus can no longer manufacture IPLEX as of a statement released in July 2009.

Treatment is based on the underlying cause, if any. Where the likely underlying condition is known, treatment of this condition is indicated treated to reduce progression of the disease and symptoms. For cases without those conditions, there is only symptomatic treatment.

Treatment of HH may consist of administration of either a GnRH agonist or a gonadotropin formulation in the case of primary HH and treatment of the root cause (e.g., a tumor) of the symptoms in the case of secondary HH. Alternatively, hormone replacement therapy with androgens and estrogens in males and females, respectively, may be employed.
