I've found that ibuprofren will help ease the pain- I do about 400mg a shot, generally this will help the whole day. It's also an anti- inflammatory (as I'm sure you know) so it will help with the swelling.

I took a spill the other day (embarrassed to say I sideswiped a post on a bike trail), and luckily didn't do much except get some bruises as well as a bit of a shock. At the recommendation of my riding pal I immediately took Ibuprofren and was able (after resting and eating) to ride home- 30+ miles. That was last Tuesday and I'm finally to the point where I don't need any more of that stuff!

If I were you, I'd still get your wrist looked at especially if you can go in during office hours tomorrow. Better safe than sorry.

Tracks are a pain- we have lots around here and many people have suffered crossing them at a bad angle.
