A foot blister is a small pocket of fluid that forms between layers of skin after irritation or injury. Blisters commonly develop on the heels, toes, or soles when repeated rubbing damages the skin. They can make walking uncomfortable. Although friction from shoes is common, blisters can also develop after burns, contact dermatitis, or insect bites. Knowing the cause can help protect your feet. Early care can protect damaged skin.
Friction is more likely when shoes are too tight, too loose, or poorly fitted. Heat and moisture can increase irritation. Burns may cause blisters after contact with hot surfaces or liquids. Contact dermatitis can trigger itching, redness, and fluid-filled areas after exposure to an irritating substance. An allergic reaction may cause swelling and itchy blisters. Insect bites can also produce localized swelling and blistering. Sensitive skin and sweaty feet may increase risk.
Symptoms depend on the cause, but often include a raised area filled with clear fluid, tenderness, or itching. Pressure can increase pain. If the skin breaks, bacteria can enter and cause infection. A podiatrist can examine the blister and surrounding skin to identify the likely cause. Treatment may include protecting the area with a dressing, reducing pressure, and carefully draining a large or painful blister, when appropriate. Footwear changes may prevent recurrence. The exam can also check early for infection.
Do not intentionally pop a blister unless a podiatrist recommends it. Keep the area clean and protected while it heals. Seek prompt medical attention for spreading redness, warmth, or fever because these symptoms may indicate infection. Persistent blisters may need evaluation. If you have frequent or painful blisters on your feet, it is suggested that you consult a podiatrist for effective relief and management tips.
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 one of our podiatrists of Front Range Podiatry. Our doctors can provide the care you need to keep you pain-free and on your feet.

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.
