Blisters are small pockets of fluid that occur on the top layers of the skin for several reasons. Friction, burns, and diseases are all known causes of blisters. Smaller blisters are known as vesicles, while larger blisters are referred to as bulla. The fluid inside the bubble can be blood, pus, or serum; which is a clear liquid that protects the skin. In most cases, blisters are not a major health issue, but they can be an indicator of a more serious condition.
Causes of blisters vary. Blisters are commonly caused by wearing poorly fitted shoes that rub against the foot. However, there are many other causes besides from friction; including burns, sunburn, insect bites, frostbite, poison ivy/oak, chemical exposure, impetigo, eczema, viral infections, and more.
Most blisters heal by themselves and do not require immediate medical care. If you have a blister, do not pop it since this may cause infection; it is advised to put a bandage over the blister to protect it. If the blister is large, causes pain, or if you have a fever, it is recommended that you see a doctor who can provide proper care. Blisters are easy to diagnose, and if considered prudent by the doctor, can easily be drained of fluid with a sterile needle as well.
To prevent blisters on the feet, wear shoes that fit properly and don’t cause rubbing. Socks can help prevent friction and it is recommended that you wear them if you are wearing shoes. Hand blisters can be avoided by wearing gloves during activities that cause friction against the hand. If you have a blister that pops, do not remove the dead skin, wash the area, apply antibiotic ointment, and cover with a bandage. It is okay in most cases to not seek immediate medical care for a blister if it was just caused by friction. However, if the blister causes pain or does not go away, it is suggested that you see a doctor for a diagnosis.
Blisters are a common annoyance caused by friction. They usually appear on the back of the ankle and are visible bubbles filled with fluid. The fluid inside of a blister varies. A blister can be filled with pus, blood, or serum. This condition causes itching, pain, or discomfort. Discomfort is usually unavoidable when the blister is located on the back of the ankle, because it will rub against any footwear. Blisters shouldn’t be popped because exposing the skin underneath could easily lead to an infection. If a blister does pop, then stay away from alcohol, hydrogen peroxide, and iodine. It is best to clean the skin with warm water and a gentle soap. After washing the area, apply antibiotic ointment and cover loosely with a clean bandage. There are situations when blisters should be drained, but it is best to let a professional drain the bubble. If you have an uncomfortable blister and would like to learn more about how to properly treat it, then it is suggested you consult with a podiatrist.

Foot Blisters
Foot blisters develop as a result of constantly wearing tight or ill-fitting footwear. This happens due to the constant rubbing from the shoe, which can often lead to pain.
What Are Foot Blisters?
A foot blister is a small fluid-filled pocket that forms on the upper-most layer of the skin. Blisters are filled with clear fluid and can lead to blood drainage or pus if the area becomes infected.
How Do Blisters Form?
Blisters on the feet are often the result of constant friction of skin and material, usually by shoe rubbing. Walking in sandals, boots, or shoes that don’t fit properly for long periods of time can result in a blister. Having consistent foot moisture and humidity can easily lead to blister formation.
Prevention & Treatment
It is important to properly care for the affected area in order to prevent infection and ease the pain. Do not lance the blister and use a Band-Aid to provide pain relief. Also, be sure to keep your feet dry and wear proper fitting shoes. If you see blood or pus in a blister, seek assistance from a podiatrist.
