I would think any illness would exacerbate MS symptoms. I was DX at 27, I'm 35 now, and I've never had the chickenpox, so shingles aren't anything I can get either. I wouldn't think there would be any connection between the two, just out of my own experience. They think MS is contracted by a virus... what that virus is I don't know, nor has anyone been able to figure it out. I was hospitalized when I was five with some unknown illness fever of 108, terrible pain, so much that they couldn't even touch me, they had to put me on an ice mattress to keep from cooking my brain, high dose penicillan shots in each leg every 4 hours. 4 days later, I was well, and I mean overnight well. Stumped the doctors... Perhaps it's has something to do with high fevers in general... Just a thought.
