Blisters
Blisters are small pockets of fluid that occur on the top layers of the skin for several reasons. Friction, burns, and diseases are all known causes of blisters. Smaller blisters are known as vesicles, while larger blisters are referred to as bulla. The fluid inside the bubble can be blood, pus, or serum; which is a clear liquid that protects the skin. In most cases, blisters are not a major health issue, but they can be an indicator of a more serious condition.
Causes of blisters vary. Blisters are commonly caused by wearing poorly fitted shoes that rub against the foot. However, there are many other causes besides from friction; including burns, sunburn, insect bites, frostbite, poison ivy/oak, chemical exposure, impetigo, eczema, viral infections, and more.
Most blisters heal by themselves and do not require immediate medical care. If you have a blister, do not pop it since this may cause infection; it is advised to put a bandage over the blister to protect it. If the blister is large, causes pain, or if you have a fever, it is recommended that you see a doctor who can provide proper care. Blisters are easy to diagnose, and if considered prudent by the doctor, can easily be drained of fluid with a sterile needle as well.
To prevent blisters on the feet, wear shoes that fit properly and don’t cause rubbing. Socks can help prevent friction and it is recommended that you wear them if you are wearing shoes. Hand blisters can be avoided by wearing gloves during activities that cause friction against the hand. If you have a blister that pops, do not remove the dead skin, wash the area, apply antibiotic ointment, and cover with a bandage. It is okay in most cases to not seek immediate medical care for a blister if it was just caused by friction. However, if the blister causes pain or does not go away, it is suggested that you see a doctor for a diagnosis.
Blisters on the Feet
Blisters on the feet are often caused by friction, pressure, or irritation. Friction blisters, the most frequent type, typically form when ill-fitting shoes rub against the skin, leading to the buildup of fluid between layers of skin. Symptoms include redness, swelling, and the formation of a small, raised bubble filled with clear fluid. Blisters can be painful, especially when walking or standing. Common causes of blisters include new shoes, prolonged walking, or activities that cause repetitive rubbing, such as running. Excessive moisture or sweaty feet can also contribute to blister formation. A podiatrist can help by assessing the severity of the blister and offering safe and sterile wound care. If a blister is infected or causing persistent pain, this type of doctor may recommend drainage, dressing techniques, or the use of specialized footwear to prevent further irritation. Custom orthotics or padding may also be suggested to reduce friction. If you are dealing with this issue, it is suggested that you schedule an appointment with 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. Stephen Petrofsky of Florida. Our doctor can provide the care you need to keep you pain-free and on your feet.

What Are Foot Blisters?

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.
