I have had this surgery 3yrs ago.
I did almost the same thing you did! I was shooting my bow one afternoon when i felt something pop? I just shrugged it off as i thought it would go away? But it didn`t it just got worse over time.
I was also going to the gem about 4 to 5 times a weeki could pick up any weight i wanted tobut i had trouble just taking off a t-shirt? Pain[&o]Like a spike was driving down through my shoulder everytime i lifted my arm up above my head or just shoulder height? So i went to the doctor luck would have it he also bowhunted

I told him my story on what had happened.
He sead let me guess? He put his hand on the top of my shoulder and pushed down?Thepain hit me harder than ever! "I sead thats it"!
He sead you need surgery to fix it?
Well i put it off for about a yr and halfuntill i couldn`t take it anymore.
So i called the doctor back up and told him lets do it.
After the sugery the pain was bad i am not going to lie about but it.
Buthealing was much faster than everyone told me it would be.
Believe it or not i was back in the gem about a month and a half after the surgery. I had to take it easy of coarse but no more pain!!
and i shoot my bow just as good if not better than before.
I know what your feeling about the surgery but believe me if i knew how it would turn out i would not have waited a yr to do it.
Other guys that i have talked to say the same thing i did about if they had any idea how it was they would have had it donesooner.
I hope this helps.
