pain
"I have taken every pain medicine and muscle relaxer I think there is and finally I have found something that has so far been very effective with minimal side effects.  I have a lot of side effects from most medicines and that is why it's been hard to find something that works.  I've had chronic/severe neck and shoulder pain for 12 years and get cervical epidurals. I don't worry about addition either because I'm in this for life and will gladly settle for it."
