I have been officially diagnosed with sfn based on a punch biopsy. Dr. believes some type of autoimmune issue, yet none shows on blood work. Have suffered with extremely painful feet for over a year. First dr. diagnosed rsd and put me on prednisone. Prednisone actually worked, but after about 6 months I decided I did not want to be on this long term and went to another neurologist for opinion. He did the punch biopsy which shows significantly reduced nerves. Started me back on higher dose of prednisone and lyrica. Looking for any other suggestions. Anyone know of any specialists in this in NY? Dont think I like these drugs but need to be able to walk.
