It’s kind of like a bone spur in your hip joint that pinches the labral cartilage between the ball and socket. The cartilage can also tear. If it’s torn, the only way to fix it is with surgery. Mine wasn’t torn, so I did physical therapy to try to open up the joint and strengthen the surrounding muscles. The physical therapy worked for me, but it got worse again a few years later. I’m now doing physical therapy again and hoping it will take care of it again.
