1. Try RICE for strains and sprains
If you’ve sprained your leg, fallen, or sprained or sprained your knee, it may help to remember the acronym “RICE”:
Get up and apply a cold compress or ice pack to the knee. Frozen vegetables, like peas, also work if you don’t have ice on hand.
Wrap the knee in a compression bandage to prevent swelling, but not so tight that it cuts off circulation. As you rest, keep your foot elevated.
