The first Neuro I saw at Johns Hopkins specializes in MS. I feel he lost interest after I was negative for that. He was going to refer me to a peripheral nerve specalist but when the skin biopsy came back negative for SFN I was told it wasn't indicated. That left me and the local neuro to try some meds he recomended. Kind of frustrating when you feel dropped by a doc who won't even refer you to someone else. My local neuro referred me back after she ran out of ideas for pain relief.
