Blisters are the skin's natural way of defending itself. They are also the result of some sort of trauma to the skin, such as a burn. If the burn is severe, then a doctor should be notified and the burned area should be examined for proper treatment.
Leave the Blister Alone
The unbroken skin over the top of the blister is your body's way of protecting itself from bacteria and possible infection. Unless the blister is too painful or prevents you from functioning normally (i.e., using your hands or walking), it is best to just leave it alone. If the blister is small, try covering it with a small bandage. For a larger blister, use a gauze pad that is plastic-coated. Just be sure the gauze will absorb any moisture and that it is porous enough for the wound to breathe.
Drain the Blister if Necessary
If the blister is too painful to leave alone or is preventing you from walking or using your hand, it is okay to pop it. Start by washing your hands and the area surrounding the blister to prevent infection. Use a sharp pin that has been sterilized with rubbing alcohol and poke through the edges of the blister in several spots to allow the liquid to drain. Some people also prefer to clean the blister area with rubbing alcohol to further reduce the risk of infection.
Caring for a Drained Blister
Using an antiseptic after draining the blister is a highly-effective method of preventing infection and quickening the healing process. Wait until the blister is completely drained and has dried before applying the antiseptic. Keep the blister covered with a bandage and continue to keep a clean bandage on it until the blister is fully-healed. Change the bandage at least once a day. Once the skin over the blister is dry, cut away the dried skin with scissors or tweezers you have sterilized with rubbing alcohol. Then recover the blistered area with a bandage and antiseptic until fully-healed.
