Hello sarahsweets. Ow, how bothersome!
Yes, I've had the RC surgery a number of years ago now and it was one of the best things I ever did! I had just come off a complicated surgical/PT/craziness post-surgical reconstroction, with much hardware, for a shattered L femur, and was weary at the very idea of having more orthopedic intervention. But (IMPORTANT!) I trusted and liked my ortho surgeon, and he said the RC was going to get worse. So I did it, did the PT faithfully, and haven't had much issue with it for the decade since!
Tears don't normally resolve by themselves, and repair is a godsend imo. Much luck to you
Best,
Chyia, orthopedic patchwork lol
