welcome, and I am sorry you had to go into the hospital, thats never fun.

MS is a slow disease to get a diagnosis with. They can diagnose you with very few lesions, but then they need to see you have at least 2 flairs that are separate, and follow certain criteria.

There are more than 100 diseases that can mimic MS, brain lesions and all. its really quite a large challenge to get someone diagnosed sometimes.

I am sorry you dont feel well,and hope you get answers soon.
