Pain is caused by actual or potential tissue damage, and a bruise damages the capillary beds and subcutaneous tissue in the area - this causes an inflammatory process, which is why bruises usually feel warm for a while after they happen, and why they take a while to form after you've bumped into something or been hit. They hurt because the tissue is damaged, and that signals the nerve endings that serve the area.

A bruise is a reaction to trauma. The colour is caused by blood that has escaped from a blood vessel (usually a capillary) and is now just occupying space in your tissues. It gets dark as it loses its oxygen similar to a blood blister, but spread out.
The pain is caused by the trauma that created the bruise in the first place. The pain will continue until the tissue can get enough oxygen again.

A bruise forms because of bleeding under the skin. Sounds like it would hurt, right?

Bruising is bleeding under the skin and usually caused by trauma-bump, hit etc. which causes inflammation which causes pressure which causes the end result-pain!

your platelets clot, thus you have a bruise after being abused. Bruises don't result from other parts of the body. Your platelets get torn and you have a purpulish black bruise.
