I hurt my arm
This is what my arm looks like 4 days since it was sprained while
snowboarding at Killington, VT in 1997.
My forearm bent back in the wrong direction 90 degrees at the elbow while trying to catch my fall in the halfpipe.
Here you can sort of see how my right arm is fatter than my left.
Notice the lack of veins and bones in my right arm.
And here's a closer view of both arms
Thankfully nothing broke and it is pretty much all healed now (2001).
