Still waiting on a diagnosis. Had MRI's of Brain and all 3 sections of spine, EMG/NCS, countless blood tests, probably a dozen general neurological exams. Nothing abnormal found. Between 4 different neurologists, all they will diagnose me with is "disturbance of skin sensation". The neuromuscular specialist said skin biopsy was not warranted. My general neurologist said testing has reached the "point of diminishing returns" for me - so he's not recommending anything else. (All he wants to do is provide symptomatic relief through medications.)

My primary doc is the only one to actually say my symptoms sound like an ideopathic neuropathy. But again, that was not an official diagnosis.
