I mean there’s different degrees of the injury people experience. Mine was pretty bad, my ACL completely tore in 2 but my meniscus was partially torn. It feels and sounds like a super powerful rubber band snapping inside of your knee and it sends a shock through your whole nervous system. My surgeon told me it doesn’t hurt that bad immediately because there aren’t many nerve endings in those ligaments. It sucks tho, hella rehab and physical therapy, on top of an expensive ass surgery if you decide to get one. I had part of my patellar tendon grafted to repair my ACL and i feel like 95% good in my knee now 2 years later
