You need ENOUGH localized inflammation. Frequently one will cause a heightened state of inflammation via exercise or manual therapy and then squealch the overflow via ice. This induces a macrophage influx and a tendancy to lay down connective and scar tissue in a BENEFICIAL manner. I like acupuncture, love Andrew Weils comment on Naturopaths ("Why would I send someoen to a poorly trained physician...") and love the smart use of cryotherapy to enhance recovery.
