What is the worst that you've been injured? For me, it was a torn ACL. Didn't really hurt that much but had to have surgery. After the surgery, I was feeling pretty good and didn't think I needed to get any painkillers. Somewhere around midnight, I realized that the reason I didn't feel any pain was BECAUSE of the painkillers I was given at the hospital. My knee felt like it was on fire until first thing in the morning when a buddy of mine went and got my prescription. Wow, did that hurt!!!
