Early onset osteoarthritis, becoming much more common and more diagnosed. But there is no more insight on treating it. Doctors have little to say but "your screwed, you could get a hip replacement...at 42?" I want to know what's causing it, I need to know if it's my genes, or my physical habits. There are no glaring things like being too heavy, or being an athlete. It's all over my sacrum and symphysis joint and my hips. So what causes this? Don't doctors know anything?
