I am getting ready to have my 3rd surgery on my leg/foot I broke 2 years ago. Coming out of the annesticia (spelling ?) I experienced the worst pain ever. Last surgery even worse. I now have 8 screws, large plate ankle totally fused. Morphine, dialatin NOTHING touched my pain. I am told my pain receptors have been destroyed from a long history of substance abuse (cocaine) Clean 15 yrs. Has anyone else experienced this problem?
