Most blisters happen from irritation or other damage to the skin from something outside the body, such as a shoe. Some illnesses can make blisters. A single blister is usually from friction or a burn, typically on the hands or feet.
Several other conditions can cause them to form. Burns are probably the second most frequent cause of water blisters. Second and third degree burns may quickly blister. Since burns of this type can cause damage to the skin, they usually require treatment with topical antibiotics to prevent infection.
