Medial Heel Pain

I've worn out the search button...

It's not the walking surface of my foot, it's posterior to the malleolus and below it, on the inside of my ankle/foot. The left foot is worse than the right.  So far my searches have yielded tarsal tunnel syndrome.

Anyone ever have this happen?  I'm going to the Dr on Tuesday, just wanted to know if this has happened to anyone else...
