You need another doctor. Any Dr who thinks its ok to have a structural tendon be torn and not need repair is a dumbass. Tendon tears don’t heal themselves. You may end up with some scar tissue over it and but its still susceptible to a full blow out.
i consulted two orthopedics , both are head ortho surgeons .
and no idea where you came up with " Torn structural tendon" , my tendons are fine, its just the shoulder labrum that has been torn . And its finally getting better, i scheduled another Mri in mid october . Cause labrums never heal by themselves …so interested to see what has/is happening
