What does your doctor say?
I love working with folks who have dislocated (not strained or sprained) their shoulders... over and over and over again. They have these intense shoulder surgeries, their arms are sewn down (cuz that's the only way to sew them on anymore) and they look at me with teary mournful eyes and say, "I wish I'd listened to my doctor. I can't believe just picking up my cat after my dislocation was enough to destroy my shoulder for the rest of my life."
Someday I will videotape one of them; the look of misery and regret and lost hopes plastered across their despairing faces will be so educational for others.
(I've got two right now who had to have reverse shoulder arthroplasties due to re-dislocation. They will never be able to return to their sports. Ever. The hardware in their shoulders holding their arms on only goes so far. They will be lucky if they can comb their hair when all is over. And boy, is it over now. Don't be that person. I get tired of watching the weeping.)
