Side Effect: Loss of Circulation in the Hip Joint

Have you experienced this?
How have you treated it?

I discovered this back in '93 and my doctor blamed the Predisone. Both of my femur ball joints are affected and my pelvis has tilted to relieve the weight pressure, which causes me to gimp. Swimming and stretching are very helpful but my flexibility is nearly zip due to my muscles tightening to protect the jonts.

Thinking about seeing a Chiropractor to straighten my spine some.?
