Rest: Avoid any activity that causes pain or further injury.
Ice: Apply ice packs for 20 minutes at a time, several times a day.
Compression: Use a bandage or wrap to compress the injured area and reduce swelling.
Elevation: Keep the injured area elevated above your heart.
Referral: Seek medical attention, especially if the injury is severe or doesn't improve.
RICER is a commonly recommended first-aid protocol for acute injuries like sprains, strains, and bruises.
It's important to note that the acronym PRICE (Protection, Rest, Ice, Compression, Elevation) is also commonly used, and the only difference is the inclusion of "Protection" instead of "Referral".
Both RICER and PRICE are good guidelines for initial care, but it's crucial to seek professional medical advice for any serious injury.
