Yesterday Ryan(not Gracie) had me in an arm-bar from the mount. I rolled into him, like I usually do and started to pull my arm out, like I always do. I got his hips below my elbow and I started to turn onto my belly to finish the escape. This is the part where a.) at best, I get side control or b.) at worst, I end up in the guard, but with my arm free. I must have done this escape succesfully at least twenty times now, and I feel really confident here, so it came as a total shock when I felt my rib cage tear open and heard my ribs make a terrible, loud popping sound. This sound was accompanied by an explosive pain in my chest and me tapping. Ryan was like " why are you tapping? You got out!", but I knew I was done. Has anyone else had this, or am I a trailblazer? I went to the doctor, he thinks grappling is more dangerous than drinking and driving, btw. I haven't broken any bone, but I may have torn cartilage in my ribs. Hooray! 3 week vacations suck! What takes longer to heal? Torn muscle or torn cartilage?
