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?
