Pro,

I agree with Mark and bud. I had similar issues at the beginning of my recovery (26 months ago that is) and it wasn't until I talked to my doctors and started getting help with my anxiety that these started to go away.

I had similar problems with bending down and even walking. It has taken a long time but it has gotten better! I'm riding a stationary bike for 30 minutes at a nice pace and I can even shoot a basketball without causing my symptoms to flair up! Hang in there it may take a while but you'll get there
