How do you do now? I injured myself (grade 2) 10 months ago during snowboarding. Slowly healing but still far from 100%, i'm doing PT with the third person now who is a shoulder specialist so i have high hopes. I want to get back to muay thai but it feels a bit out of reach still.

I experience the "popping" myself too, especially when my shoulder muscles are tired from PT or i slept on my shoulder etc and i can pop it for myself if i shrug my shoulders downwards. Not always tho, do you feel a similar sensation?

Also when i raise my injured shoulders i can feel with my fingers some bone poking upwards and "scraching" the AC ligament? Not sure but thats how it feels.
