Most trusted means to reduce swelling from a bee sting?

Quick fix: When our bodies sustain an injury, the immediate response is inflammation (red, hot, tender swelling). This is the body increasing the blood flow to the injury to bring healing factors to the area and also the veins expand to carry bad stuff away. The key is to do things that reduce the parts of inflammation such as ice, compression, elevation and antiinflammatory medications in the first 24hrs.
