Neuromas

Commonly called a Morton's neuroma, this problem begins when the outer coating of a nerve in your foot thickens. This thickening is usually caused by irritation that results when two bones repeatedly rub together (often due to ill-fitting shoes or abnormal bone movement). The area between the third and fourth toes is the most commonly affected; the area between the second and third toes is another common irritation point. Nerve problems due to diabetes or alcoholism may also cause neuroma-like symptoms.

Symptoms
The pain from neuromas may start gradually, causing burning, tingling, cramping, or numbness. Symptoms often occur after you've been walking or standing for a period of time. It might feel like you're stepping on a lamp cord. You may need to take your shoe off and rub your foot. In some cases, the pain radiates from the tip of the toes to the ankle.
