Hey Neal. Keep up the good work my friend. Take it from a person who had a total replacement done of the right shoulder. THREE TIMES. It became infected. It is all about the rehab. Hours every day for 8 months for me but now I have almost total range of motion. The worse part was I couldn’t play guitar for about 6 months
Continue the good work and work hard at it. It pays off. By the way, it sounds like you haven’t missed a beat with your playing. I only wish I could play like that.
My wife had knee replacement several years ago. The best advice I can give you is to apply pure coconut oil several times a day. It really does reduce the scarring. Gotta keep those knees looking good for the camera!
