muscle spasm
"I have fibromyalgia as well as muscle spasms related to lordosis and to an orthopedic problem, as well as dysmenorrhea.  Skelaxin is my rescue medicine. If I get a calf spasm in the bad leg that a hot pack and some stretching won't subdue, half a Skelaxin will do the trick, no sedation, just good work. I'd give it a ten if it weren't so very expensive!

When I have the very bad cramping related to my menstrual period, 100 mg of tramadol and 400 mg of skelaxin will make me drowsy and unfocused, but it means that while I can still tell I'm cramping, it's like someone shouting inside a house while you stand outside, and I can get on with things as needed."
