A neuroma is an inflamed nerve, which causes a bulge or increase in size of nerve.  This tends to happen in the feet when neighbouring bones press against the nerve, causing the irritation and inflammation.  Poorly fitting shoes contribute to this issue.  Pain can be recreated by squeezing the outer edges of the foot together, while pressing directly under the ball of the foot.  When the clinician conducts this test, it helps in diagnosing the pain as a neuroma, as they can feel the enlarged nerve "pop" between the bones when pressed.
Usually the symptoms include pain, numbness, or a tingling sensation.

Treatment for this condition is determined based on the extent of the symptoms and the patient's choice of conservative versus direct treatment.
