I had THR in August 2008, the proced1ure I had done was the Anterior replacement technique. I have been in some sort of pain ever since. It seems that whenever I first stand on my leg the pain is almost unbearable, but after being on it and walking the pain will subside. I have had one epidural about 3 weeks ago in the L5 area, and am scheduled for another one next week in the S1. the first epidural was almost useless as the pain came back. I am experiencing the pain in upper left hip and in front of my leg in the thigh area. I have tried several pain relievers but any long term consumption of those brings on other problems(constipation), etc. Does anyone have any answers or suggestions?
