Ice a Cold Sore

Ice a Cold Sore

As soon as you feel a cold sore coming on, apply ice to the area, say experts at Case Western Reserve University. Put an ice cube in a handkerchief and hold the cube on the area for 15 seconds, then off for 15 seconds. Continue alternating for 15 minutes. Doing this may prevent a blister from forming.
