muscle spasm
"I was in a car accident and my neck/shoulder was extremely painful. I don't like doctors, but after 3 weeks I gave in a went to urgent care.  I don't take medicines and have always done the alternative or holistic remedies.  Not knowing anything about drugs, he gave me this script for Skelaxin with some samples to try before filling the script.  I have only taken 1 tablet at night for the last 3 days.  I noticed today I can move better.  Everything that has been hurting feels better.  What's more, there is no side effect.  I just found out from my research tonight that this is a muscle relaxer.  This stuff is a wonder drug.  I feel so much better and don't feel like a zombie."
