Hard enough that I have a pretty big scrape/gash

But, that's not really the problem.. the sharp, shooting, razor like pain up and down my lower leg (though my knee and through my foot) has me more worried. It doesn't really hurt more if I walk.. but it hurts more when I stand still.

Didn't hurt on the bike earlier, because yes, I was stupid enough to just decide to ignore the pain and ride anyways. (I slipped when we were getting ready to leave.. took a few minutes to rest, another 10 or so to ice it, I bandaged up the scrape, and then decided it would probably be okay.)

It's almost 4 hours, and it's still throbbing and feels like it's on fire

Not in a "hey I racked my shin on something" sort of way.. I did that to the other one getting the kids in the car this morning, and I have a big lump and developing bruise to show for that.. this is way worse.

Should I go get it x-rayed in the morning? Part of me wonders if I'm just being silly and overreacting, but.. it hurts!

Help?
