I dug a left hand holster for my Sig 320 out of my training box. I dang sure am not going anywhere unarmed with only one hand working right.
my BIL had his done like i said, and my chimney guy was over doing the yearly inspections.
they talked about it, now mind you a chimney guy, has to carry x amount of bricks to the roofs...
heavy
he told my BIL that once you are healed, you will be like a mother hen to the shoulder and every little thing you do, will make you scared into thinking you did some more damage...
he said his doctor told him, "that's a normal feeling"
my BIL goes bowling, that's how he totally lost his arm, his arm fell to his side with the 16 pound bowling ball in his hand.
indicating a tear, and for him, it was a severe tear.
he had the operation, and had to wear that stupid appliance for like 10 weeks, and after 1 full year of no bowling, he and his wife go weekly, and it's like nothing ever happened.
it was all done laparoscopy..??? small incision.
so hopefully if it is a torn cuff, you may have caught this earlier than my BIL......meaning far less recovery times, and PT
best of luck, and if you need help shooting your guns, i'll volunteer to shoot them for you.
you just supply the ammo...of course.
