I've been told I have PIN and Morton's Neuroma by different specialists. Living with that belief for a few years, and trying different supplements and nutrition to help alleviate the pain. A couple of weeks ago I came across some info online about Tarsal Tunnel Syndrome which has almost the same symptoms as the PIN and Neuroma. I contacted a doctor in Maryland who claims that nerve decompression would improve sensibility. I have an appointment for a consultation. I'm beginning to believe that none of the doctors so far really know what's going on....Is it PIN, Morton's Neuroma, or Tarsal Tunnel Syndrome? That is the question I hope to find the answer to with this new doctor. I've got nothing to lose so we shall see!
