Neuropathy has a wide spectrum, and in my experience, neurologists are the doctors best equipped to diagnose and possibly offer treatment. My Rhode Island neurologist, teaching at Brown University sought a second opinion from her neurologist colleague at Massachusetts General in Boston. They both settled on an autoimmune cause for my neuropathy, based on a number of blood tests, EMG’s, a spinal tap, and a nerve biopsy. I had to be willing to go through those tests and okay their recommendation for iVIG infusions to reduce nerve inflammation. It has also reduced pain, and added to range of motion and strength. There is support here, and support groups through the Foundation for Peripheral Neuropathy, and the Western Neuropathy Association. So, you do not have to be alone in this struggle. That has helped me, and I hope it will help you.
