Here's a link to the symptom list at the National MS Association site. Their list would probably be a better guideline as it would encompass more people then a small sample elsewhere.

This site says that when symptoms occur, it's called an MS episode. When they go away, it's called remission.
You do need ongoing with a neurologist, first for a diagnosis then for followup treatment. There are mimics to MS, such as Lyme Disease and Meniere's Syndrome, so be sure that your diagnostician is thorough.
