My first DX came from a general Neurologist. He did Evoked Potentials,
MRI, numerous blood tests ruling out other stuff, a Lumbar puncture all saying suspected MS. The man had no bedside manner at all though he was a good doctor. I next saw a MS specialist in a MS center and due to their moves, am on my 5th neurologist, my MS never questioned, but MS can be tough to diagnose. Many get a second opinion. Sometimes years can go by before someone questions DX. It happens.
