True, but there is not much to the program. The doc' told me that all the therapy and weight lifting in the world wouln't help because there was nothing wrong with my shoulder or arm, the problem is where the nerve root comes out of my cervical vertebrae, and the only thing that will help is time because nerves are the slowest healing tissue in the body. That makes it a little frustrating, but today I curled a 30# dumbell which is way up from the 10# that I started out with. I've got an old 1969 Bear Polar at 28# that I'm shooting just to keep my mind right, squirrels beware.
