This sharp thigh pain is more prevalent than I first thought. Sometimes time with regular walking helps. Some medical doctors speculate Fosamax can help over time. It seems that if time does not cure it, that is 1-2 years depending on who you talk to or what you read, the only option is further surgery. One surgical option is to approach it directly at the end of the stem and stabilize the stem, the other option is a complete revision. I will be at the 2 year mark in August but am SO reluctant to undergo more invasive surgery. I still have this thigh pain yet no loosening or infection. It’s distressing to say the least. I wish my original surgeon had told me about this particular possible outcome because I doubt I would have agreed to it. You can imagine that this micro motion of a metal stem in one’s body would of course cause pain with movement and no meds or exercise seem to help it. More should be known and discussed about this topic. My best wishes to all of you who have it. Fingers crossed for us!
