Did some more research and re-read my "leikkauskertomus"...what's that in english? I'll just call it as "that paper the surgeon writes about the operation"

Anyway...it says that the anterior joint capsule had also been torn with the labrum and that there were no tears in the rotator cuff. So I'm thinking there must be scar tissue in the anterior joint capsule and that's what's limiting my external rotation ROM...would make sense, would it? I'm no PT nor SC professional...only self-learned one
So let me refrase my question? What would be the best way to stretch the joint capsule? I've read here that mild long ( 20-30 min ) stretches keeping the stretched area warm and applying cold afterwards...is there any other efficient ways to accomplish this? Like I said, I feel i've gotten some results with the aggressive approach described above...
