21 months out from first hip replacement on left side. Last few weeks have had some pain in my left leg, lower thigh area towards the outside/back and about 4 to 5 inches above my knee. Pain seems to radiate through the back of my knee? Primarily when I get up after sitting or first thing in the morning. It comes and goes but not an issue when exercising. When its “on” however I can barely walk without limping. Anyone have anything similar? Going to see doctor but wanted to feel the water with the HipRunner crew.. Thanks!
