Had right hip replaced 12/19/11, went thru therapy and recovery & by April I was feeling good - no pain, able to sleep on both sides, continuing strengthening of muscles, etc. Middle of August I started wearing a more supportive shoe due to some foot pain, and within a couple of weeks I first got a pain in my right knee, within 2 weeks was feeling pain & stiffness in my hip. Xrays say prothesis is good. Doc says I have problems in my knee and pain in hip was transferring from knee, had cortisone shot, helped some but not all the way, am having further knee treatments (if insurance ever comes through), but I still feel I'm having a problem in hip as well. My pain is in my groin area, and my hip won't bend, even as much as it was in August, and it's hard to lift my leg to get into the car, I can't reach my foot and I have a constant ache - not as bad as before surgery, of course, but it often wakes me up at night. If I'm going to live with this I can get used to it, but why was I good for 4½ months? Any similar experiences?
