muscle spasm
"I was prescribed this medication to treat musculoskeletal issues in my upper back. The pain was chronic, I've had it off and on for almost a decade, and it was severe enough to impact my day-to-day life. This medicine eased the pain almost entirely without crazy side-effects. It is the only medication that has ever worked for me. I've been on Soma and Flexeril in the past, and both did nothing for my pain- they just made me groggy enough that I didn't care as much."
