Didn't have surgery, but I had an "off bike" accident 2 years ago that stuffed up my right shoulder.
it is just now getting to where I have full range of motion again, without it hurting me.
Just sitting still on the little scooter I have, a 250cc Piaggio talking with neighboring campers.
and poof!!! the pine needles and wet oak leaves went sliding down hill and left me on my side laying on a rock....
used up all of my Medicare benefits in Therapy, did not help a thing..... time was what it took.
