Blisters are fluid-filled sacs that look like fleshy bubbles on the skin. They appear when the top layer of skin separates from the lower layers. The most common type of blister occurs on the feet as a result of friction from shoes that don’t fit well. Blisters may also form from other conditions such as sunburns, contact allergies, or may be a sign of an autoimmune disease.

What Are The Symptoms Of A Blister?

Blisters begin with redness in the spot where there is irritation and can be itchy. Eventually, a painful, bubble-like sac appears on the affected area. If the fluid sack is ruptured, the blister can become infected and begin to form pus. If the infection progresses, red streaks will form on the skin running upward from the site of the blister, indicating cellulitis. If a streak develops or you begin to run a fever, seek prompt medical treatment.

What Causes Blisters?

Friction blisters develop as the result of unusual, chronic irritation on the skin. While blisters can form anywhere on the body, the most common places for them to form are on the feet and hands. Shoes that don’t fit properly are the main cause of blisters on the feet. On the hands, blisters commonly form from manual labor with shovels or other tools, or extensive playing of stringed instruments. Other causes of blisters include contact with irritating substances or even an autoimmune disease. If blisters persist, and you are unable to identify a direct cause, it is important to have them evaluated to determine their cause.

Blisters Treatment

What is the best blister treatment? Most blisters don’t require medical treatment and can be handled by first aid that you can administer yourself. The first step is to protect the irritated area as soon as you see signs of redness that signal the development of a blister. Apply mole skin or similar padding to the affected area. Another option is to cover the area with petroleum jelly – it will provide temporary pain relief. In order to prevent the formation of friction blisters be sure to wear appropriate footwear and gloves when working with your hands.
