How do you treat a grade 1 ankle sprain?

A grade 1 ankle sprain, which involves mild stretching or slight tearing of the ligaments, can be treated using the RICE method: rest, ice, compression, and elevation. Rest the ankle and avoid activities that cause pain, apply ice for 15-20 minutes every few hours to reduce swelling, use a compression bandage to limit swelling and provide support, and elevate the ankle above heart level when possible. Over-the-counter pain relievers like ibuprofen or acetaminophen can also help manage discomfort. Most grade 1 sprains heal within a few days to a week with proper care.
