Blisters

What Are Blisters?

Blisters are small pockets of fluid that form on the upper layer of skin. They commonly appear when the skin is repeatedly rubbed against something, which causes a tear in the epidermis. Immediately, the body reacts by rushing fluid and white blood cells to the area in order to protect it.

Causes of Blisters

Blisters can be caused by a variety of things, such as:

• Friction from ill-fitting shoes or clothing
• Burns
• Allergic contact dermatitis
• Infection

Blisters are highly prone in sports and professions that involve lots of physical labor. Some workers who frequently lift, push, or carry heavy objects can also be at risk of developing blisters.

Symptoms of Blisters

Aside from fluid-filled pockets on the skin, blisters are usually not accompanied by any other noticeable symptoms. Some people may experience a bit of discomfort or a burning feeling. Depending on the cause, these blisters may also be filled with pus.

Treatment for Blisters

Blisters typically heal on their own within a few days to weeks. The best way to treat them is to keep them clean and covered with a bandage. Do not burst these blisters, as this increases the risk of infection. In some cases, a doctor may prescribe a topical antibiotic ointment to prevent infection.
