Did your GP mention Lyme Disease? There are so many autoimmune diseases that mimic each other in symptoms. You'd have to be tested to eliminate each one. MS is a member of the autoimmune group. Usually a diagnosis of MS is after all other possibilities are eliminated. I'm sorry you have to wait so long to see the Neuro but you can take your notes and questions with you to your appointment and hopefully get some answers.
