I guess I pushed my left shoulder too hard raking wet leaves yesterday. Giving me issues during certain motions. I can feel a tendon "clunking" in there when I move, and reaching behind me to scratch my lower back is a bad idea, I have discovered. Partner ordered a shoulder support device cause it's becoming obvious I've done enough damage over the years it needs some external help/also some self PT to strengthen muscle groups for better internal support. Aye, gettin old.
