Causes of Blisters

If you’ve worn shoes that fit incorrectly or are too tight, the friction that occurs may cause blisters to form on the toes and feet. They are observed as small areas that are filled with fluid, which is often seen in the top layer of the skin. The blister serves as a defense mechanism to protect the skin against germs and infections from entering the body, as a result of the skin disintegrating from excess pressure. There may be many causes of blisters, including sunburn, frostbite, or a skin condition such as dermatitis. Some people may find that insect bites may be a cause of blisters, in addition to having an allergic reaction to specific chemicals. Research has shown the importance of leaving the bister alone until it can dissolve naturally, which generally occurs when the skin is fully healed. Preventative measures can be taken by ceasing to wear the shoes or stopping the activity that caused the blisters. For severe blisters on the feet, please speak with a podiatrist as quickly as possible to learn how they can be treated properly.

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. Lori S. Weisenfeld of New York. Our doctor 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.


(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.
