muscle spasm
"I had a very strange episode of a serious neck cramp. I was still able to move it, but if I did, I would get a constant dull to sharp pain. In fact, I could only sit in one particular position in order to subside the pain. I took some Skelaxin and a small dose of Hydrocodone. It was without a doubt the best way to get rid of that pain. After about 45 minutes of taking it, I was feeling 90% without sleepiness or 'weirdness.' Highly recommended."
