Be, go buy a heating pad and if you must, an electric blanket. When mine is hurting badly, I turn the electric blanket on and get in bed and let the blanket drape over the parts that hurt.

You can hold the heating pad on the front for a little while and then on your back for a little while. Be really careful not to burn yourself. It's easily done because the muscle pain tends to be greater than the burnig sensation.

I hope you feel better soon!
