You may have reached or pushed past your tolerance level for overhead movement following the labral repair.
Following the labral repair you are a different athlete.
Not good/bad just different.
There is less room for deviations in technique.
You may not be able to buffer the same deviations in technique that you were once able to buffer.
Spending time re tooling overhead movements with skill and drill work will help to dial your technique.

Hey I also ask looking for any advice for my son. He is 15 yrs. And is a wrestler. After almost every match he experiences major pain where he can not move it. We plan on surgery after the season is over.
We have been doing dry needle and cortisone shots. Any info on what we should do
As far as mobility or ways to lower the pain would be highly appreciated.
We are pretty sure it is a slap tear and not just a ac. Joint issue. I say that because we
Rested it for at least three months, then strength trained for 5 months and now it is wrestling season and he is dealing with pain and stiffness after a wrestling match.

Has your son seen a doctor about this?
Has he had any PT for the situation?
Some may be improved by improving his position when sitting in class & standing.
