Cheers!
I had glenoid labrum tear a few years back, which wenleftbalone and treated with some fairly uncomfortable physio - I felt that having a shoulder being held static for a few months wasn't going to work for me, and I trusted my physio to be able to fix it. I was fortunate enough that it did.
At the moment, I don't know - I've doctors to see and scans to be made. Apparently, it's not good at fixing itself.
Saying that, it's pretty clear to me that the main damage was done back in '12, about half way through a marathon.
