I didnt want pictures ow that must have bloody hurt, i remember i did the same once when i had a new bike when V-Brakes recently came out, was going really fast pulled on breaks and went head over bars and sprained my arm.
i also fell off my bike when i was learning to ride, i was about 6 and when i fell off my finger nail fell off on my index finger.
and when i was about 12 i went down a huge rollin at my local skate park just as a kid on a bmx was crossing it, he got knocked off and my back hit the thumb box coping.
i have had accidents all my life as im what people call "accident prone"
i also regulary fall down the stairs now and then brusing my arm.
