muscle spasm
"I've been on Robaxin since 3/11 when I suffered neck/shoulder injury/trauma and a compression fracture in my lower back due to an auto accident. I take it in conjunction with Lortab 10/500 for muscle spasms and pain. It has helped with pain relief. I can continue to drive for work which I drive in excess of 25,000 miles per year. It seems to have little if any side effects."
