I'm sure this isn't your circumstance, but we have had this occur on 3 different occasions:
1) Drinking during Avonex night.
2) Getting very overheated.
3) Day 3-5ish following a Novantrone infusion.
Perhaps #2 could apply. We need to be carfull in the summer. 30 minutes of gardening in 95 degree weather just about does it.
It would be really nice to be able to put links in here
If I have included a bad link, google the word "Scholar", click link for "Google Scholar". Search for the name of the paper and author in Google Scholar.
