This is an enlarged benign (not dangerous)growth of a nerve.
Most commonly between the third and fourth toes which is called a Mortons Neuroma
The issue is caused by the tissue of the nerve being rubbed or squashed.
Pressure from ill-fitting shoes or abnormal bone structure can create the condition.
Treatment includes orthoses (shoe inserts) as a first treatment which can be very successful. Should this not address the condition, steriod injections or surgical intervention may be required.
