I've been taking pain meds for years including muscle relaxers, Cymbalta, and Vicodin.
I'm really concerned about long term kidney function and eventual kidney failure. This concern/fear prevents me from taking an appropriate dose to relieve much of my pain. I've seen many doctors and haven't found any that are truly helpful. I don't think they have any answers.
I have failed back surgery, steroid injections, and both have not helped. I also do electric stimulation.
