I have never been in remission since I was dx -- if you define remission as a total lack of symptoms. But I do not think I am in a continous flare. I believe this is just damage caused by the lesions. I have taken mezclizine (spelling) for vertigo. It tends to help more with the nausea than the actual sense of vetigo. I do know a few people that have a constant problems with vertigo, and I have also heard that it generally is caused by a lesion on the brain stem. I know that there are also some treatment for those who have dizzines due to inner ear problems.
