I have just started learning to play golf. I used to play baseball most of my life. Trying to change my swing, I have hit the ground several times jarring my back. I have a knot on my left side right under my ribs, mid back.,  I have taken tylenol but the pain just wont go away. I start feeling better then I just turn or do something wrong and it drops me. I tried using heating pad and Aleve. I cant even pick up a slightly heavy object
