I really wouldn't consider this as being 'blown off'. After all, he has done a very thorough work up hasn't he? I only think of doctor as blowing off patients when the discontinue testing prematurely, I don't think that is the case here. He may just not have any other ideas and needs to step aside at this point.

I don't think you should just give up. But I think you should focus on symptom relief...trying different treatments and supplements until you find the right combination that works for you. It never hurts to consult with other doctors for fresh ideas, so I would continue to explore an occasional neurologist. Just try to understand that they are limited also, so don't have overly high expectations.

I waited many years to find out what was behind my problems...and still waiting for a few answers now. Trying to focus on issues you can treat and improving your quality of life in regards to pain, etc would be best. You know this isn't in your head and I feel certain it will present itself when the time is right...then everything will make sense.
