Being that I have an anxiety disorder, this problem only exacerbates my issues. Last week I noticed that the inner top third of my little finger began to ache periodically throughout the day. I also am having intermittent aching deep in my thigh just below my groin. I have had neuroma surgery on both feet after a neurologist felt I have idiopathic neuropathy. All tests for pn came back negative, and a podiatrist felt the pain in my feet, which were only on the bottom was morton's neuroma. 6 months post-op, my feet still don't feet good. They don't burn anymore, but they are very numb and do ache if I overdo it. Now...With the finger/thigh thing, of course i'm convincing myself that it truly is polyneuropathy and it is spreading throught my body. I am a nervous wreck. I had a skin biopsy....Emg....Blood tests....They all came back normal.
