Forgot to mention this in the earlier post. Look at a "Cryo-Cuff". Looks like a knee brace but is set up to circulate ice cold water from a cooler. Water circulates through the brace. I've used one after the last couple surgeries. It's an amazing device. In about 15 min. the knee is as cold as a quarter of elk that's been hanging in the cooler for a day. Takes away swelling and pain. The web site has "cuffs" for most parts of the body.
