I've never done this before, but I had to leave work early. I have a "laundry related injury" and was lucky enough to be able to see my chiropractor. (He only practices a few hours a week)
After injuring my back, I really shouldn't have hauled heavy baskets of laundry, and a huge heavy box, but at the time I didn't realize that I had done any damage. I just thought my back was sore from bending over a table, folding clothes.
I couldn't sleep very well last night---there was no position that was comfortable.
So...adjustment, ice, Aleve. It's hell getting old!
