Question

Should I use ice on an ankle sprain?

Answer 1

Yes, you can use ice:

It will reduce the swelling, redness, and warmth.

Ice will counteract the increased blood flow to the injured area.
Applied soon after the injury, ice will prevent much of the inflammation from happening.
Do not apply ice directly to the skin. Use a thin towel between the ice and the injury, or use an ice bag. Apply ice for 20 minutes at a time, with at least 20 minutes between applications. This is to help prevent frostbite, which can occur if you use ice too much or use it directly on your skin.
