I'm sorry I have no advice as to what you should do next.I'm a few days away from being diagnosed,I believe anyways.But I do understand your frustration with the neurologist.Trust me when I say most neurologist are over rated and give neurology a bad name all together.I've been through 4!!!Well I'm on my 4th one now and the sad thing is she's the NP of the neurology department I go to,and so far she's the best.I even traveled 3 hours away to the reputable Cleveland Clinic in Ohio,only for the neuro to give me a routine exam and send me on my way.All I can say is hang in there and hopefully the right doctor comes along sooner than later.Best wishes to you.
