Yes !: Couple of days of absolute rest, muscle relaxants , anti inflammatory drugs, steroids , localized injections weight reduction etc. See your md.

Pinched Nerve: Sounds like you have a pinched nerve in your back. I would suggest seeing a pain/spine specialist to evaluate you further to evaluate what level and what can be done to treat you. There are interventional treatments besides medications and surgeries that might reduce or eliminate the pain altogether.
