Hi and Welcome to NeuroTalk. I'm not going to give you any advice on this, as I am not familiar w/wrestling injuries or the success rate of disc surgery.
I have two herniated discs, L4-L5, of which I just live with and when they act up, I slow down and rest. Of course, this would be troubling for your Sports minded son.
I hope you can get some answers and help for your son. You sound like you are very close. Welcome again.
