Minor rotator cuff problems with my left shoulder here. Got it back to normal about 4 years ago then fell while skating and was back to square one. At least second time around I knew what exercises would help.
When you think about what we ask our shoulder joints to do, I find it amazing we get so far before we are reminded to take care.
Last summer I got on a pair of rings in a playground and went inverted then over. Fantastic that old shoulders could do that!(Hey, I was with my granddaughter, showing her how.
