An enlargement on the top of the middle part of the foot can be from a bone enlargement or spur. This can cause pressure to the nerve, the deep fibular nerve (deep peroneal nerve), as it courses over the top of the foot. The pressure can cause compression to the nerve resulting in pain, numbness, tingling or other sensations which may go into the adjacent sides of the big toe and second toes. The spur can also cause a ganglion in the area which can also put compression on the nerve and give similar symptoms.
If you are having any of these symptoms, give Dr. Harvey Danciger, Podiatrist in Palm Desert, CA a call for treatment. 760-568-0101 or request an appointment online.
