Most blisters caused by friction or minor burns do not require a doctor's care. New skin will form underneath the affected area and the fluid is simply absorbed. Do not puncture a blister unless it is large, painful, or likely to be further irritated. The fluid-filled blister keeps the underlying skin clean, which prevents infection and promotes healing.
If you have to pop a blister:
- Use a sterilized needle or razor blade (to sterilize it, put the point or edge in a flame until it is red hot, or rinse it in alcohol).
- Wash the area thoroughly, then make a small hole and gently squeeze out the clear fluid.
- If the fluid is white or yellow, the blister may be infected and needs medical attention.
- Do not remove the skin over a broken blister. The new skin underneath needs this protective cover.
- Look for signs of infection to develop. These include pus drainage, red or warm skin surrounding the blister, or red streaks leading away from the blister.
