Scratched eyeball - had to drive home from the gym practically blind as occasionally my eye would tear up, my vision would go blurry, then firey pain making me squint.
Neck injury - a white belt tried to guillotine, was actually a bad neck crank. Couldnt even turn my head for like 2 days... that was over 4 years aho and my neck still isnt the same... I can only pop my neck one way now.
Knee injury - drilling kimura sweeps with a big guy, while taking him over his body weight came down on the side of my knee.. that was over a year ago and its still a little stiff.
Wrist injury - popped the joint or a tendon on my wrist (pinkie side) finishing an ezekiel choke
Thumb injury - scissor swept someone and they drove their weight forward onto the proximal joint of my thumb, with an audible pop. It was about 2 months ago and still hurts.
Rib injury - had someone in an omoplata, he stepped across to defend so I shifted under and swept him, but he had a metal knee replacement and he tried to sprawl to stop me, it cracked the cartilage and seperated at my 5th rib. Im currently recovering from this one, been out a full month and its killing me... still hurts like a bitch and the worst injury ive had by far.
