Have you had a lumbar puncture, repeated MRI? To be honest I would ask to see a different doctor. When my husband took ill, very sudden onset (similar symptoms to yourself) our doctor seemed unconcerned, suggested it could be viral. I was having none of it, I had already done quite a bit of studies on ms due to a neuropsychology course that I was studying, and he was showing all the signs. So I insisted he got in the car and I drove him a 90 mile round trip to A&E. I told them I was concerned and they needed to rule out certain conditions, they did all tests required and unfortunately a diagnosis was met. We have been repeatedly told that stress has no impact on ms, but I tend to disagree!!! Numerous people have shared how a stressful situation has led to a relapse!!!
