What are Blisters?

13 July 2015 | John

A blister is a small pocket of fluid on the skin that forms over a break or damage to the skin. Blisters are a key part of your body’s defences against further damage, cushioning the affected area. As they are the most frequently aggravated parts of the body, blisters usually form on feet and hands.

Depending on the blister, it can contain a fluid called serum or if it is a blood blister it will be filled with blood. If infected or inflamed it will be filled with pus. Most blisters clear themselves up over the course of a week and should not be popped. Popping a blister only slows down the healing process and opens the wound underneath vulnerable to infection.

Though blisters are mostly harmless to people without underlying conditions, if you are suffering from a disease like diabetes, blisters can cause complications that you are better off avoiding.

What are the Symptoms of Blisters?

A blister is a very obvious thing, and usually do not cause any pain or discomfort other than what would be expected from a lump on your skin. In addition, an infected blister can cause pain. Infected blisters contain yellow or green pus, are red around the edges and hot to the touch.

What are the Causes of Blisters?

Blisters can be caused by a number of factors — a single blister can be a result of friction; for example your foot rubbing up against the inside of a new shoe. Blisters caused this way are often a result of frequent exercise.

A burn can cause a blister to form, for example after being scolded, to protect the damaged skin underneath. Blisters can also be caused by extreme cold; if a wart is frozen off, a blister will form.

If you have blisters across your body, it can be a symptom of an infectious disease, such as chickenpox or shingles.

How can a Shoe Insole Help with Blisters?

One of the things a shoe insole can do to help with blisters is that it can reduce the chance of them getting infected. Many shoe insoles have an antimicrobial coating that kills the bacteria that could potentially infect blisters.

A shoe insole can also help reduce the chance of blisters developing; blisters are more likely to develop on moist skin and the right shoe insole can help get rid of moisture. The softer surface that a shoe insole provides can also help reduce friction in your shoes, reducing the chance of your suffering from blisters.

In addition to traditional shoe insoles, a heel grip can help reduce blisters by preventing the heel from rubbing against the back of your shoe, stopping blisters from developing on around your achilles tendon.
