Morton's neuroma, also known as Morton's metatarsalgia or interdigital neuroma, is a health condition involving perineural fibrosis and the common digital nerve degeneration in the foot.
Morton's neuroma is caused by irritation or thickening of a digital plantar nerve located between the toes in the foot, which can occur as a result of multiple causative factors.
It is unclear whether those factors are directly associated with Morton's neuroma or whether they increase the risk of an individual who is already susceptible to symptoms from the disease.
Morton's primary symptom of neuroma is severe pain between the toes or at the base of one or both feet, which may in some cases prevent them from moving normally.
If the area between the third and fourth toes is usually affected but other nerves may be affected.
Initially, patients often report a tingling sensation that worsens gradually until it becomes severe and is often described as a sharp, shooting, or burning pain.
Some patients also report lack of feeling and numbness in their feet, while others describe the pain as being similar to walking in their shoe with a pebble.
During activities which put pressure on the feet, such as walking or wearing tight-fitting shoes, the pain usually increases in intensity.
Conversely, the symptoms usually improve if the patient can rest or remove the shoes that are unfitting.
Patients may experience a flare-up with frequent symptoms over a period of a couple of weeks, followed by another remittance period with no evidence of symptoms.
Some patients may go up to one year without symptoms, though the attacks tend to increase over time.
Individuals reporting Morton's neuroma symptoms should seek medical advice on the appropriate treatment because the condition is usually chronic and does not spontaneously subside.
Initial neuroma treatment for Morton usually involves simple changes in lifestyle to eliminate the likely cause of the condition.
Corticosteroid injections can also help to decrease nerve pain and inflammation, helping to ease some of the symptoms.
These non-surgical techniques are able to provide sufficient relief in most cases, with more than 8 out of 10 patients.
Some patients will need surgical treatment to resect a portion of the nerve or release some of the surrounding tissues for symptoms to ease.
