What Is the Difference Between a Regular Blister and a Blood Blister?

Tuesday, 08 February 2022 00:00

Blisters are fluid-filled bubbles of raised skin that typically form on the feet due to excessive, repetitive friction over a concentrated area. The fluid inside blisters is most often clear and acts to protect the raw skin underneath the blister from further harm. However, some blisters are filled with blood, instead. This happens when a blood vessel is damaged and blood leaks into the skin. Unlike regular blisters, blood blisters are usually the result of a sudden impact or pinching of the skin, rather than friction. The skin underneath a blood blister may be more prone to infection, so it is very important that you avoid popping or otherwise irritating the blister. If you have particularly painful blisters on the feet, have blisters that appear to be infected, or get blisters very often, it is suggested that you seek the care of a podiatrist. 

Blisters may appear as a single bubble or in a cluster. They can cause a lot of pain and may be filled with pus, blood, or watery serum. If your feet are hurting, contact Dr. Jeffrey Bruening and Dr. Thinh T. Le from Bruening Foot & Ankle. Our doctors can provide the care you need to keep you pain-free and on your feet.

Foot Blisters

Foot blisters are often the result of friction. This happens due to the constant rubbing from shoes, which can 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.

Symptoms

(Blister symptoms may vary depending on what is causing them)

  • Bubble of skin filled with fluid
  • Redness
  • Moderate to severe pain
  • Itching

Prevention & Treatment

In order to prevent blisters, you should be sure to wear comfortable shoes with socks that cushion your feet and absorb sweat. Breaking a blister open may increase your chances of developing an infection. However, if your blister breaks, you should wash the area with soap and water immediately and then apply a bandage to the affected area. If your blisters cause severe pain it is important that you call your podiatrist right away.
