Hi TooYoung4Hip:
You have a right to be frustrated - anatomically, your pelvic alignment has changed since your hip replacement surgery! Now the question is what to do about it.
I suggest you get an evaluation from a physical therapist you like, and move forward aggressively from there. You need to get your body as fit and balanced as possible so that you can have your active, pain free life back again.
I found that for me, the best post op activities to get going again were the Pliates reformer work, yoga, and swimming.
From reading your prior posts I do know that you have a post op leg length discrepency which is actual and not functional. The reformer work will help you deal with the uneven pelvis by helping you get as balanced as possible and strengthening your core muscles, back, glutes, hamstrings, etc. It is a very good tool for working with "new equipment" post op. I suggest you go to a sports oriented physical therapy practice that uses the reformer, and not just to a Pilates studio.
I know this is VERY hard for you - you didn't expect to have this problem post op. Remember that your hip joint has been repaired, and you are strong and healthy. I'm rooting for you. You can do this!
Take good care,
Ruth Z
