How Can Severe Pain In The Body Be Treated?

I spent months on Norco , & tramadol , & decided , the effects were not to my liking , My pain level has dropped now to between 6-7 . At times of activity more severe ....I was recently prescribed Cymbalta , 2 days ago ...after researching, the adverse conditions Reported by users , have kept me from using it , What are the best alternatives I have chronic pain, & nerve damage, From a terrible accident . I ve had spinal injections which help for a short time, I do not like doing them, I took Xanax years ago, But as the pain subsided I stopped , However it was effective , & I found I could use it sporadically as needed .... Is it not a recommended medication now? I m a bit nieve , I didn t realize there was a fee, No C.C. LOL Just my luck
