Has the pain management doctor said anything about a nerve ablation? I had knee replacement 1 1/2 years ago and have been in constant pain since (also had taken NSAIDS long term which messed up my stomach to the point I needed gastric bypass surgery). After being told I could no longer take NSAIDS my primary physician prescribed tramadol and referred me to a pain management doctor (by my request as I didn't want to be on narcotic medication any longer than necessary). After battling with the insurance company for 4 months I finally had a diagnostic nerve block last month which took away the pain temporarily. On Friday I go in for an ablation which should help the pain for 1-2 years.
