Not so fine now

I wrenched my back this morning while, of all things, sitting in my office chair. It felt like somebody stuck an ice pick in my lower back. Anyhow, I was fine for a couple hours while the muscles in my back tightened around my spine. Then, around 1300, I had had enough and went to lie down to relieve the pressure and pain.
I'm going to try and find a chiropractor here on the base. I hear there are a couple reservist chiropractors here performing other military jobs. I'll see if I can bribe one of them for an adjustment. I need to get better before the cruise.
ouch.
