muscle spasm
"This was prescribed to me for back pain. I had a pinched nerve in the middle of my back. 
I've also had back pain due to muscle spasms/Strained muscle. This is by far the best med I've taken so far (cyclobenzoprene, Flexeril, Hydrocodone to name a few). Most medications either make me too drowsy, constipated, or leave odd mucus on my stool. Methocarbomal leaves me functional & eliminates spasms. It makes me slightly woozy feeling if I haven't eaten anything, but that's only for about 20 minutes, then it seems to go away. 

*These taste horrible* but if I'm in pain, I don't care. 9/10 for this

I'm not a heavy med user, and I honestly don't like taking medication. As soon my pain became manageable, I stopped taking these..But they DO work"
