In fact, when you have a foot problem, even one as seemingly innocuous as foot blisters, it can negatively impact your activity level. The following is pertinent information explaining everything you need to know about foot blisters, a foot condition that should not be overlooked:

How to Care For Foot Blisters: Everything You Need to Know

What Are Blisters?

Blisters are fluid-filled pockets that form on the uppermost layer of the skin. They are often a response to an infection or injury. It is the body’s way of protecting itself from further harm, by cushioning a vulnerable area of the foot. Blisters usually appear as a small red sore first, then as you continue to put pressure on the area, the top layer of your skin is sheared. The body then reacts by sending fluids to protect this opening and prevent underlying tissue from damage…forming a blister.

How Do You Get Foot Blisters & What Causes Blisters?

Causes of foot blisters include:

  • Friction & Pressure: In most cases, your foot blister forms because of friction and pressure. Friction and pressure are often caused by your foot rubbing consistently against a rough surface, sock or shoe, which results in inflammation and irritation. Friction related blisters can be disabling and painful or tender to the touch.
  • Burn: Your blister might instead be the result of a burn. If you have been burned, your skin will again attempt to protect itself by forming a blister. The blister won’t appear for a few days after the initial burn if the burn is first degree, such as a sunburn. If the burn is more severe, the blister will form immediately.
  • Freezing: The opposite end of the temperature spectrum can also cause a blister to form. If you experience frostbite, a blister can form because of exposure to extreme cold damaging the skin.
  • Contact Dermatitis: This inflammation occurs when your skin is exposed to an irritant such as an allergen. This reaction can occur because of insect bites or stings, reaction to chemicals like washing detergents or soap, or skin reactions to various types of chemicals, cleaners or solvents.
  • Various Medical Conditions: Your skin can become damaged and form a blister as a symptom of many types of medical disorders and/or diseases. For example, autoimmune conditions, eczema, and certain medications can cause a skin reaction that could lead to blister development.

Blister Prevention: Is it Possible?

Yes. The best way to prevent foot blisters is the following:

  • Get Shoe Insoles: Do this to prevent chafing and friction.
  • Use Foot Powder: This is especially important if you are an athlete. You want to keep your feet dry to reduce friction.
  • Make Sure Your Shoes Fit: Make sure your shoes fit properly. This will ensure you do not develop friction related blisters.
  • Avoid Known Allergens: Eliminate any product that causes a reaction on your skin.

Should You Pop Foot Blisters?

No, in most cases you shouldn’t. However, if the blister is especially large and painful, you can pop it but should sterilize the tools you use.

When Should You Treat a Blister at Home?

In most circumstances, you need not see a podiatrist for a foot blister. You can usually treat it yourself at home. Leave the blisters intact when possible and cover with a blister bandage to prevent pain and tenderness. Once the blister burst, clean the area with soap and water then cover with a dry, sterile breathable dressing.
