Medical Feature: Blisters
Most people will experience a blister or two over their lifetime. A blister is basically a fluid filled bubble that forms when the top layer of the skin known as the epidermis separates from the deeper levels of the skin. They can be caused by friction, burns (heat, sun, or chemicals), exposure to cold temperatures, and infection. Some times blisters are a also a symptom of certain diseases. The purpose of the blister is to protect the skin below it - preventing further damage and allowing the area to have time to heal. The blister can be filled with an amber colored fluid called serum or blood or pus - depending on how the blister is formed. Frictional forces are the most common cause of the formation of blisters like wearing tight or ill-fitting shoes or doing simple repetitive things like walking or running. Hands are feet are the areas that seem to be most vulnerable to the formation of blisters especially since these areas are subject to repeat frictional forces.

Most blisters will self resolve. The skin under the blister will heal and the fluid will resorb and usually the top of the blister becomes dry and will shed. We recommend that you leave the blister alone and intact since it is in fact it's own bandage and is acting as protection from infection. If the blister is too large or in an area that is inconvenient to have a blister it can then be ruptured by first cleaning the area with soap and water then inserting a clean, sterile needle into it and gently pushing on it to allow the fluid to seep out onto a clean dry gauze or cloth. Once the blister is collapsed then an ointment like Vaseline or Aquaphor or and antibiotic ointment should be used across the surface and a band-aid placed over it to prevent pain and infection.

Blisters can be prevented if doing things to reduce the friction across the area. Simple things like wearing proper fitting and comfortable footwear and socks can prevent blisters on the feet. Physical barriers like tape, moleskin or padding can be utilized as well in prevention and make blisters less likely to form in response to the repetitive trauma across the prone areas like feet and hands. If you think that the blister is infected we suggest you schedule a visit with your provider to advise you if any further treatment is needed.
