Maybe look into femoral stem pain (FSP). I had a pain just like you described (front and/or side of thigh) and my doctor and I agreed it was probably FSP. FSP has to do with the difference in flexibility between the implant and the bone. His take was that once your bone beefs up around the implant, it should go away. Mine seems to have. Oddly though, I never had it in my first THR but I have had a few twinges now in that hip. I think it might have to do with changes in torsion in my legs. I recently started walking on the beach with only walking poles and I notice I no longer duck walk so my whole leg has changed. I am 6 months and 3 months out on bilateral replacement and things keep getting better. Still a lot of fatigue but I am either walking a mile or swimming 1/3 mile daily. My doc said if FSP is not better in 1 year he would suggest a surgical fix. I made a thread on FSP.
