Blisters

What is a Blister

A blister is a small pocket of fluid in the skin. There are many ways in which a blister can form, and if located unfortunately enough it may interfere with daily activities, especially on the feet. 

Causes

A blister will form for any reason after enough irritation on a certain area on the skin. These irritations include fiction, burns, cold, and irritants or allergies, drug reactions, autoimmune disease, infections, and genes. A blister can form when something rubs up against the skin, but unlike calluses, a blister will form after a very brief, quick, and intense contact with a small area. Blisters can also form from burns, getting to close to flame, smoke, touching a hot surface or even a sunburn. Extreme cold can cause the skin to blister as well - if you've ever had to have a wart get frozen off your skin may have blistered. The final cause of blisters is irritant such as chemicals or allergy trigger such as plant allergens. A blister can form from a reaction to a drug you take. There are several autoimmune diseases that can cause the skin to blister. Blisters can form from infections such as chickenpox, shingles, or impetigo. Rare genetic disease can cause the skin to be fragile and blister. 

Treatment

A blister will get better on its own usually in a week or two. While the blister is healing you should stay away from whatever cause the blister in the first place.

 

Steps you can take during the healing process include:

• Put on a loose bandage to protect the blister while it heals

• Keep you blister padded, if it rubs up against the shoe, add extra padding underneath the bandage to keep it from becoming more irritated. 

 

Generally, a blister will not need to be drained, but if it becomes large enough and hurts you then you may decide you want to drain it. If you decide to drain it, sterilize a small needle with rubbing alcohol, then pierce it. After you will want to wash the area with soap and water and cover with petroleum jelly. 

 

If you suspect the blister becomes infected at any point call your podiatrist.

Signs of infection include: 

• Pus leaking out

• Redness

• Swelling
