If you’ve ever hurt your ankle or had another type of sprain or strain, chances are your doctor recommended rest, ice, compression, and elevation (RICE) as one of your first treatments. The RICE method is a simple self-care technique that helps reduce swelling, ease pain, and speed up healing.

You can treat minor injuries with the RICE method at home. You might try it if you have an achy knee, ankle, or wrist after playing sports. If you have pain or swelling that gets worse or doesn’t go away, see a doctor.

The RICE method includes the following four steps:

Step 1: Rest

Pain is your body’s signal that something is wrong. As soon as you’re hurt, stop your activity, and rest as much as possible for the first 2 days. Don’t try to follow the “no pain, no gain” philosophy. Doing so with certain injuries, like a moderate to severe ankle sprain, can make the damage worse and delay your recovery. Doctors say you should avoid putting weight on the injured area for 24 to 48 hours. Resting also helps prevent further bruising.

Step 2: Ice

Ice is a tried-and-true tool for reducing pain and swelling. Apply an ice pack (covered with a light, absorbent towel to help prevent frostbite) for 15-20 minutes every two to three hours during the first 24 to 48 hours after your injury. Don’t have an ice pack? A bag of frozen peas or corn will work just fine.

Step 3: Compression

This means wrapping the injured area to prevent swelling. Wrap the affected area with an elastic medical bandage (like an ACE bandage). You want it to be snug but not too tight — if it’s too tight, it’ll interrupt blood flow. If the skin below the wrap turns blue or feels cold, numb, or tingly, loosen the bandage. If these symptoms don’t disappear right away, seek immediate medical help.
