I am 18 months out and notice it in my shoulders. I mention this to the Drs and they sort of say ....we did not do rads on your shoulders ? But it seems like I do feel it more now after doing a lot of yard work. Perhaps in my mind or just collateral damage. Although it has not seemed to help golf game...maybe I need more Rads...maybe not ! Played 108 holes the other weekend and was sore but I do think that was more to old age and not being in golf shape. Maybe your better golf is from a slower swing ? Still trying to get that concept through my hard head !
