When I had appendicitis if u can call that an injury, but I remember laying on the floor with my eyes closed because the pain was so bad, I didin't know what the fuck was going on I waited almost a week when their was really no pain at all any more, I still went to the doc and sent me to get a ct scan where they found out it was swollen to shit. Crazy to think though the first couple days of pain I was just doing normal shit if it would have ruptured, it would have been all bad.......
