The best thing to do is to follow up with a neurologist, in particular if you can find one specializing in ms.

Yes, it is: Depending on the severity of the multiple sclerosis and its activity in the brain, CSF studies indicating immune activity may not be detected in mild cases with minimal involvement in the brain.
