I made it to the doctor this morning and luckily I have no nerve damage in my back. Still don't know what caused the back pain, but at least I have some options now. I'm going to book a chiro/massage appointment, and my doctor gave me some anti-inflammatory pills and some Valium (it's a muscle relaxant and has the fewest side effects -- who knew?). So I've temporarily become a 1950s housewife, popping Valium and dozing on the couch. All I need is a box of bon-bons and an apron. Oh, wait....
