This seems to be a common problem with Neurologists. Finding the right one is like finding a needle in a haystack. It's been over ten years for me to get a diagnosis and it was from a Rheumatologist. Maybe there's something lacking in their education that causes them to be so dismissive. I'm sorry you had to go through this and I hope you find someone who will give you the treatment you need and deserve. I'm sure there are some good Neurologists out there...somewhere...
