Back Spasms and Heating Pads

I can't take any pain killers like ibuprofen or naproxen. Which is too bad, because they're great for taking the edge off the pain of back spasms.

I've been told that back spasms should be treated with ice. But ice doesn't make them feel any better, and heating pads do. Today's spasm is much better, thanks, after the heating pad treatment. I was able to go to work in the afternoon.
