I asked my daughters trainer if we should be icing after she pitches and he told me...only of she is real sore, then ice would help with the sore muscles......otherwise we should put heat on it. He said that heat pulls blood to the area and helps heal any damage better than anything else can. Of course, those weren't his exact words. He explained it much better then I ever could. But, he also said that if she gets done pitching and feels like a million bucks, there is no need to do anything.
