It worked great when I had strained muscle and spasm,combined with phys.therapy everything healed well,no longer needing flexeril.
Many years ago I had a pinched sciatic nerve, and the med helped then too,relaxed the musccle that was pinching the nerve.
Any docs I have had over the years that I have seen for muscle related injury or strain, do not prescribe too many pills, nor have I had any that had a refill on the bottle.
It usually worked by the time the pills were finish.
It can make some people drowsy, so be careful till you see how it makes you feel.
I hope you'll be feeling better soon,good luck.
