Hi romans8, I've been doing joint mobility exercises for a little over 2 1/2 years now and I'm pretty sure both of my shoulders, and my left hip, were frozen when I started. They're starting to move fairly good now but it's been a lot of work. I've had TOS for more than 30 years now and had surgery on one side 21 years ago. The surgery didn't turn out too well so I've never had the other side done. These joint mobility exercises have been working really well for me, though. I have a running post about it if you want to check it out.
