I feel really quite stupid but I think I've learned from my mistake. I need to stop being so darn stubborn and not do things that my body can't handle. I was at church last night and we had to shift our bell choir stuff back into the sanctuary. Well, crazy me decided to lift a 50 pound bell case by myself instead of waiting for one of the guys to lift it. Need less to say, that did not end well. Mid-way through today, my back decided to start locking up right at about L1-2 and then the muscle spasms set in with it. Feeling somewhat better now that I'm down in bed. PCP in the morning, mainly because that spot has never bothered me before, and given the compressed discs at L4-5, I'd rather not take any chances with it. And even prescription ibuprofen is not really touching it. At a 6-7 pain level right now. Hot bath on it's way as well as another dose of ibuprofen in a few minutes.
Lesson learned: Ask for help and quit trying to be superwoman already.
