How to tape a sprained ankle?

Try U-tube: Can't explain or demonstrate here. Try u-tube or see a sports trainer to demo this to you.

Can be difficult: Depends on which part your are trying to stabilize. Athletic tape, kinesiotape/rock tape are best. I recommend mcconnell taping. There are many videos online but a good athletic trainer, primary care sports med doctor, or certified kinesiotaper can show you as well.

Home taping...: You're better off using an otc brace or splint that trying to tape yourself up at home. It's not as easy as the professional trainers make it look. You could also just see a podiatrist - many of us stock simple braces for simple sprains.

Ankle taping: Just don't go circumferential, which can cause vascular or nerve embarrassment. Go above and below the joint.
