What Causes Blisters?
Blisters are usually the result of burns or continuous rubbing or chaffing of the skin. A blister may form when the skin has been damaged by friction, heat, cold or chemical exposure. If you touch something very hot, a little bubble filled with a watery fluid soon forms under the skin. This is a blister.
Sometimes a blister forms when a shoe rubs against a toe or heel. The fluid in the blister is called lymph. The lymph aids in protecting the burned skin and prevent the burn from hurting too much. The covering of a blister protects the tissues beneath if from becoming infected. Therefore, it is best to leave the blister unbroken.
Don’t “pop” the blister; the skin covering the blister helps protect it from infection. Gently wash the area with mild soap and water or a cleansing towel and then apply antibacterial cream. Cover it with gauze and secure with hypoallergenic tape to help protect the skin and prevent infection. Change the dressing at least once a day and wear different shoes until the blister heals.
