What's funny about those "anti-ice" people is that most of them have something for sale. And they often cannot provide references supporting their situation; they just like to tell you that there aren't any sources supporting ice either.
Personally I believe it's nuts the way baseball purists have considered icing to be so crucial after pitching or just throwing in general. But I do utilize quite often for a lot of different injuries. We use our Game Ready units a ton at the high school I work at. 10-12 kids a day easily for this or that injury. Especially post-op situations the Game Ready units are life-savers. These provide both cold and compression.
