... suffer from a lower chronic back condition, a chronich neck condition, Fibromyalgia, Migraines, and Osteoarthritus in both of my knees. I tried it seems like everything until finally my pain dr. put me on Fentanyl Patches with Vicoden for breakthrough pain. I swear it works better than anything else, and I can actually play with my 4yr old some now. Has anyone else had any luck with this medicine?
