So, Good news, Bad news.
Good news: No MS!
Bad news: What now?
My son has a cyst/polyp in his maxillary sinus (under your cheek) that (at least 15 years ago) they didn't know how to remove. I would have thought that by now technology would have an answer.
Well, glad you at least don't have MS. I hope you get some help soon to unravel your mysterious symptoms and their cause.
