How do you bring out a bruise?

Well, I'll try to explain it.

Everyone knows a bruise comes out by a bump,accident,purpose injury.

The injury comes out because when for an example you bump your knee on a metal leg of a desk, the bones and the cells and stuff in the leg of your body have a reaction that cause the bruise to happen.

Fortunetly, the bruise heals so the area you bumped would be cured.

Hope this answer helps you!

Not really. yes a bruise is caused by impact but the next paragraph is wrong. A bruise is bleeding under the skin. It can be at controlled by a cold-compress (a pack of garden peas from the fridge is an oft-quoted form). The next sentence is right - bruises normally heal naturally, over time (very serious one may need medical treatment).
