Relapsing Remitting Multiple Sclerosis. Strokes, Seizure, Muscles Jerking. Visited Neurologist. What Does It Sound Like?

Two weeks ago, I had what they thought was a stroke but decided it might be a seizure. I have been diagnosed with RR MS for 14 years years. Two months ago I lost my coordination but got it back a week later. I was taken to the hospital by ambulance. I do not remember any of it. About four hours later I started waking up. My right eye would only open half way and my muscles would jerk severely every ten minutes. As time went on my eye improved and so did the jerking. The doctor ran all types of test. He could not find any damage from the stroke. He talked to my neurologist partner. They did not believe the MS might have caused the stroke. They felt that it was a seizure might have been cause by a urinary infection that just started a few days before. My right side is my weakest since coming down with MS. Since they don't know what caused it could the MS caused the seizure. My husband still things it was a stroke since I was unconscious for over four house. The first responder & ambulance driver felt that it was a stroke. Does MS cause strokes and why?
