Todd:
Glad things are going better. I seem to hurt my back doing the most innocuous things (one time, just tying my shoe!).
But usually, it is the result of weakening.
I OFTEN get a severe back issue 1-2 days after final exams week. I spend almost all of that week sitting a (giving exams, grading them, figuring and posting grades). Even with breaks, I just set up a situation for that to happen.
