The Academy of General Dentistry reports that 30 percent of Americans suffer from fever blisters, which are sometimes also referred to as cold sores or oral herpes. A fever blister usually ruptures spontaneously after four days, leaving behind a shallow pink ulcer that “weeps” highly infectious clear fluid. Popping a fever won’t make it heal faster, but some people do it for cosmetic reasons. Since fever blisters are highly contagious, you should take care to dispose of your tools when you are done.
Sterilize Pin or Needle
Wash hands with soap and water. Dry with a clean towel.
Open a package of sterile gauze. Set it aside, handling only the edges.
Light a candle or the burner of a gas stove.
Sterilize the pin or needle by exposing it to an open flame until it glows.
Place the pin or needle on the gauze for later use.
Pop the Fever Blister
Clean the fever blister with mild cleanser and water. Pat it dry with a clean towel.
Apply the pin to the blister until it pops. Discard it.
Blot the resultant fluid with gauze. Discard it. If the lesion continues to produce enough fluid to produce a drip, keep it covered with a bandage until the fluid flow decreases.
Wash and dry your hands.
