What happens if you damage an injury?

[General-Army]

My streets turned to ice, but i went out bike riding any way, i was going a good speed, then my handlebars turned in and i went down hard in a hard peice of ice. My knee was swollen and bruised, but im going to ice hockey tonight, i was just wondering if anything could hapen to my knee if i fell even though i have the shinpads on.

Now you COULD jump off a building, but.... youd die.
