A noncancerous tumour of nerve tissue. In many cases, the cause is unidentified; hardly ever, a neuroma arises as a direct result of damage to nerve.
A neuroma can affect any nerve within the body. Symptoms differ depending on the nerve involved. In many cases, there is intermittent pain in the areas of the body supplied by the afflicted nerve. The same areas can also become weak and numb if the neuroma arises in a confined space and pushes on the nerve.
If symptoms are bothersome the tumour can be surgically removed.
