The problem is not my rotator cuffs, I solve that by losing 75 pounds and fixing my posture.
Instead, I’ve got muscle cramping or knotting. Right where the triceps connect.
Not quite the shoulder. Stretching and other things haven’t seemed to help. Knocking off workouts actually seems to have made it worse.
It is worse in the morning after a nights sleep, best at the end of the day before I go to bed.
I’m still trying to figure it out. I’m 51 and never had a problem like this before.
