i have back pain whenever i sit in one place for too long. i am 49 so it may just be getting old. but i take from my psychiatrist seroeoquil, effexor, valium, adderal, and i take neurontin because i had tmj, but i have had to get teeth pulled and the tmj stopped. so i was wondering if there is something i could take for chronic back pain that don t have bad effects with my other medicine?
