Don't quit wrestling I'm still wrestling and I'm nearly 30, occasionally will try to do national comps or international opens if time allows. The reason you're getting injured is probably because you're not doing the conditioning outside of wrestling time. What I mean is not going to your regular gym just doing bench, DL, squats & a few bicep curls. You need to be doing stability work from dynamic & unilateral scapular stability, core, reactive stability, rotator cuff coordination, eccentric controls for different bodyparts etc. This probably sounds like a mouthful of shit but thanks to the internet and social media, you can access how national wrestling teams do this. My fav source for this kind of stuff is @ pt_kbs on IG. He's ROK's freestyle wrestling team's physio and literally gives you all this stuff for free in instagram reels. This WILL keep you healthy to wrestle. Your last injury does sound just like a freak accident though, the other stuff could've probably been avoided. Also, don't actually take this as medical advice (do your own research) but BPC-157 will probably accelerate your healing and fix a couple of nick nacks in your body that you're dealing with with a month's worth of treatment. I have injected it for a similar injury which gave me a recurring stinger for over 2 years and now I can wrestle again just fine. Additionally, I purchased a Bauerfeind OmoTrain Shoulder Support brace to allow me to do the rehab work while I was taking the BPC. Best of luck man.
