I have had avascular necrosis in my right hip for many years now and I'm putting off replacement surgery as long as possible. It affects my low back and right leg and something is causing my whole pelvis to tilt. It looks like I have a beer gut and my ass sticks out. It sucks, and it gets worse on leg day or if I work low back. My question is, is there excercises I can focus on to eliminate or minimize this? Is it caused by my low back muscles tightening up? Help!
