Bad news - a torn rotator cuff doesn't heal itself, or at least not in my case. I damaged mine pretty severely a year and a half ago and it continues to hurt as badly sometimes as the day it happened. I've had a lot of busted bones and other kinds of injuries and the thing that's keeping me from having my RC fixed is the rehab and PT. Been there, done that. One physical therapist taught me how to spell it. . . the-rapist!!
