Put ice on it.
Ice or a cool compress to reduce swelling.

Yes, if you hit your head or bump it ice will bring down the swelling. Ice is good for many bumps, burns, and scrapes.
To beat jack on runescape, you need to slide on the ice and bump into him.
You cannot make a bump go down fast, but putting ice on it right away may help it not to become really large. Once it is formed, it will need to go down naturally, but continuing to put ice on it for 20 minutes or so a few times a day could help.
the effect is
sprain, bruise, cut, burn, bump
Ice. Lots of ice. And if the worst comes to the worst, foundation .
The salt will quickly melt the ice
If it's really just a bump on the head, I'd ice-pack it. 30 minutes on/ 30 minutes off would be good.
because the cold slows down the particles in water until they bump&stick together. they still move by vibrating.
