Make sure it is not referred pain as it was in my case.....it looked like tarsal tunnel, but in fact was referred pain, meaning it traveled to a location and looked like TT but in fact wasn't. I had surgery and I actually had to have a second surgery to correct issues from the first one.....I think that it wasn't TT but because I have EDS I feel that is what it was.....do rule EDS out before you have any surgery.
