Types Of Blisters

It is important to understand the different types of blisters and what causes them because there may be different treatment tactics and means of prevention. The most common types of blisters include water blisters, blood blisters and burn blisters. But there are also types of blisters that may have been caused by a medical condition, including fever and cluster blisters, impetigo blisters, atopic eczema blisters, or blisters from chickenpox, shingles and dermatitis herpetiformis. Here, we will focus on the most common types of skin blisters:

WATER BLISTERS

Have you ever worn shoes that are a little bit too small? Did you get a little blister on your pinky toe or a big blister on your heel? It was most likely a water blister. Water blisters occur when there is too much friction in one place on the skin. This type of blister is usually small and contains a clear liquid called serum. The clear fluid, or serum, in a water blister protects the skin underneath and helps it heal. A water blister will not be bloody or pus-filled.

Water blisters can be painful, which most people discover when they touch them. This type of blister is tender and it can feel like it is burning when the skin around it moves. The pain may make it difficult to move, especially if the water blister is located near a joint.

BLOOD BLISTERS

A blister that appears dark red in color is usually a blood blister. The color occurs when tissue and blood vessels under the skin are damaged creating a pouch, or bubble, of blood under the skin. A blood blister can be very painful, but if left alone, it will dry up and heal itself over time. Like a water blister, a blood blister is tender to the touch and can feel like it is burning when the skin around it moves.

BURN BLISTERS

A burn blister occurs when the first two layers of skin are damaged by a second-degree burn. A burn blister is much like a water blister (except that it will be obvious it was caused by a burn as it is extremely painful). Like water blisters, burn blisters are also filled with an important watery fluid called serum. These painful types of blisters can last up to three weeks.
