Bruises are caused by which mechanism, and which treatment is commonly used?

Explanation:
Bruising happens when small blood vessels are damaged by an impact, causing blood to leak into the surrounding tissues under the skin and create the discolored area you see. The most common treatment right after the injury is RICE: Rest, Ice, Compression, and Elevation. Rest helps prevent further injury. Ice constricts blood vessels to reduce bleeding into the tissue and lowers pain and swelling. Compression with a bandage helps limit swelling by minimizing fluid buildup. Elevation uses gravity to help fluids drain away from the injured area, further reducing swelling. Heat is avoided early on because it increases blood flow and swelling. Massaging the area can disrupt clots and worsen bruising in the acute stage. Hydration therapy isn’t relevant to this mechanism.
