We have an abundance of neuros in town but we also have a big medical center and medical school up at Indianapolis so after making a preliminary diagnosis mine made a referral to see an actual MS specialist. He conferred with her in the diagnosis but was glad that I saw a specialist. Insurance paid for part of it but was able to take travel off on taxes. Just gave me a lot of peace of mind. As to your original question, I don't know the answer to that.
