I have a painful "lump" in my right calf muscle for the past 3 years that causes burning on the top of my foot, preventing me from wearing shoes, driving, walking and sleeping. I have been to many doctors and have had 3 MRIs. I've been to a rheumatologist, an orthopaedist and a podiatrist. No one seems to be able to diagnose, and no one wants to put the mass in the calf and the burning of my foot together. I am only 52 and have lots more living to do but find myself very frustrated and feeling older than I am. Not sure what to do or where to go next.
