I have been experiencing severe pain in my foot and arch for about 3 months. The pain is unbearable; I sometimes cannot walk on the foot without being in tears. The pain is now traveling up the inside leg. For months my doctor thought the pain was coming from my back. But my doctor has now ruled out that it is related to my bad back problems. My back doctor pressed on my foot near the inside ankle and I screamed and began crying from the pain. Can you please tell me what this possibly can be?
