SpongeBob,
Please understand that we do not know what your physical activity consists of each day. How many steps you take, stairs or hills you climb, time spent standing, time spent sitting, nor what your gym workouts consist of. What exercises you do, how often, how many reps….I could go on. You’ve mentioned swimming also.
It is impossible for anyone here to tell you when, or if you’ll ever be pain free. Your best bet is to follow the guidance of your surgeon who knows your medical history, or your PT who sees you engage.
You are only six months into a recovery than can take on the average a full year, and probably even longer for you, given the history you shared. So please, try to ignore that it’s not perfection and realize it may never be. I think I shared this before, but I’ll share again. Your prosthetic hip will never match your natural hip before it deteriorated. It can get awfully close, but an exact match…never.
Possibly you should consider stepping away from all of the PT exercises and any other exercise you’re doing and try walking, only, for several weeks and see if you notice any difference. Concentrating on gait and heel-toe walking. This involves striking the ground with your heel first, then rolling through your heel to your toe, and pushing out of the step with your toe. It takes a concentrated effort, but I believe you'll notice a difference. Give it a try.
Try to enjoy the rest of the week, relax and allow the healing process to continue without the worries.
