How do you treat a swollen and bruiesd foot?

Assuming there are no broken bones or tears to ligaments, tendons, or muscles, the classic first aid treatment for minor injuries to the foot can be remembered by the acronym RICE.

Rest

Ice

Compression

Elevation

Stay off the foot as much as possible, apply ice to the swollen area, use a compression bandage (ace bandage or similar) to provide support and prop the affected foot up on pillows or a foot rest.
