My tos surgery 20 yrs ago released my arm and leg. little use of armand curled in, leg was curled and dragged. i had rib resection w/ sympathectomy, scalenectomy, neurolysis of nerve root and brachial plexus, I don't know what of these things helped it. When i get stove up and they turn in some i go to Chiropractor and it helps alot.
