muscle spasm
"I have always suffered from frequent headaches/migraines, and was put on a preventative medication (Nortriptylin). This medication took care of regular headaches/migraines, but not tension related ones. I carry a lot of tension in my shoulders, and was originally prescribed Cyclobenzaprine for the tension along with (generic) Fioricet for the headaches themselves. This combo did not work, so my Dr replaced the Cyclobenzaprine with Metaxalone. This seems to have done the trick! When I feel the tension (w/o a headache) I take the Metaxalone with great results. If there is also a headache the Metaxalone isn't enough, so I add a Fioricet. So far this combo has allowed me to deal with headaches without having to go home and curl in a ball."
