May 15, 2019: Tuesday night, Wednesday morning experiencing horrible pain in left shoulder, the worst in days, could not sleep. Left arm shoulder very weak in terms of raising it above my chest, usually need the right hand to help it. Turning my neck does not increase the pain. Moving my arm in different positions is what really hurts. Just resting at night, the shoulder throbs and I get some sharp pains when I try to move it into another position. Sitting upright seems to help the most. Spent hours sleeping in a chair for relief.
