As I sit here writing, I'm in a lot of pain. The left side of my low back is throbbing. Often I can ease this pain by popping the back, but this time that hasn't worked, and neither has Advil. The next step will be to put a prescription pain patch on it.

"Depression hurts," say the Cymbalta commercials. Yes, it does, and antidepressants that, like Cymbalta, work to make more of the neurotransmitters serotonin and norepinephrine available have also been shown to relieve pain.

My questions...
