It seems that you want to improve circulation with the ice-heat applications. Am I right? Could you explaine me why you think ice or heat can change swelling?
The application of ice to an injury,in the acute phase can substantially decrease the extent of the damage. It achieves this in a number of different ways:

1. Decreases the amount of bleeding by vasocontriction into the injury site and so lessens swelling
2. Reduces pain
3. Reduces muscle spasm
4. Reduces the risk of cell death by decreasing the rate of metabolism
