Man, i've got a story to tell, but i'll reserve it for later. It would be a terrible inconvenience for you if i told more than one story or as a Lust kindly remarked; "wall of text".
I'll tell you about a few times where i've hurt myself.
Once where when i was, i believe 11 and i was playing football, and i jumped on top of the ball and lost balance, resulting in me falling down and breaking my arm close to the sholder joint. It actually didn't hurt that much, and i didnt't have to have any plaster or anything, so it didn't really bother me.
Another time, which happened when i was 15, or maybe 16 at my MMA training.
We where sparring and i had just before been at the dentist, so i was a bit groggy from all of the anesthesia. It proved a difficult task dodging and blocking, and i was sparring against someone who was verry keen on performing a double jab, which to me in my doozy state was very confusing.
Eventually he just brushed my lower lip, not very hard, but appearantly hard enough to make it rupture and spew out blood. It was painfull as all hell, even more so than when i broke my arm.
I don't know why it hurt so much, but he must have hit a nerve or something. I wish that the anesthesia was still strong enough to dampen the pain, but no. Mostly i was angry over it because it scarred, and i don't like having scars on my face, because it makes one look like a hoodrat. I do not like hoodrats.
I am not mad about it anymore, it's hardly vissible, but at the time it was looking pretty bad. It's more vissible when i've been in the sun, being that i suddenly then have a bright light line going over my lower lip on my slightly browner face.
So i haven't really hurt my self so bad, but i feel sorry for bumble, dislocated knee and hip must be painfull as all fuck.
