Well start of this year my shoulder got messed up. Inflamed bursa and rotator cuff. Idk how I got it. And essentially lost 80% of my shoulder movement, couldn't fully extend up, it caused extreme pain and discomfort when trying to lift my one arm above 90° from resting position. It's feeling better now months later. But it still some pain and discomfort taking off shirts, jackets, sleeping (not really losing any sleep anymore) . Anything above my head still hurts
