Thanks to both of you for your replies! It's been hard to find much in the research about the onset...just the stages over weeks and months. I did have an injury from an auto accident nearly 5 years ago, which precipitated the TOS. Why this is starting now, I have no idea!
Trix...so sorry to hear about the Lupus.

My sister had lupus. I've always feared it, because there's about a 30% chance of a close family member developing it. I hope you don't have it, or if so, that it will be relatively mild! It does go into remission at times, too.
Artist...I understand about needing a break...I do that from the TOS board from time to time, too.
Anyway, thanks again. I guess we'll see what happens over time!
