Did anyone experience this, post-thoracic surgery? I am seeking information...Thanks in advance.:)

Not post-operative, but I get a bout or two every year. It hurts like Hell for a couple weeks.
WITH surgery I would think it would be all the MORE common becasue of all the ligaments and tendons that have been mangled and need to heal.

Probably the best thing one could do after thoracic surgery is gentle stretches (within proscribed limits) to make sure one eventually gets back the full range of motion painlessly.
