I had a THR in November of 2014. Initially, everything seemed to be healing smoothly;however, I have this thigh pain that becomes so painful I can barely walk on my leg. I have told my surgeon who has taken xrays and says everything appears normal. I put up with a bad hip for about 30 years so I am no baby. I really feel something is wrong and I still walk as though I have an impairment. Any ideas?
