I am sure that I am in agony due to small fiber neuropathy; however, a skin punch biopsy did not show any nerve damage. Has anyone else had this same issue? I believe that my pain began with an injection of Marcaine and alcohol to treat a Morton's Neuroma. Two days after the injection, I experienced severe pain in the same leg. The pain cleared and I had a second injection with the same response. Since then, nerve pain has spread from my foot to all extremities, including face and tongue. So, a few questions:
1. Have you had a negative skin punch biopsy but still diagnosed with SFN?
2. If you have SFN, can it be tracked to the injection of a local anesthetic for treatment of a different ailment?
3. I've been diagnosed with fibromyalgia, but the level of specific nerve pain doesn't seem to correlate to FM. The pain seems much more extreme/sharp than what I've read about FM pain. Could the doctors be using FM to give a name to something that can't figure out?
Thank you for sharing your experiences with me. Up all night because the pain is so great. Any hints for that, as well??:o
