Causes and Contents of Foot Blisters

Foot blisters are fluid-filled sacs that form on the skin's surface as a result of friction, heat, or pressure. They often appear on the feet when shoes rub against the skin or when the skin is exposed to excessive moisture. Activities such as walking, running, or hiking can increase the likelihood of developing blisters, especially if new or ill-fitting shoes are worn. Inside a foot blister is a clear, watery fluid called serum, which forms as the body’s natural response to protect the damaged skin underneath. The fluid helps cushion the area, allowing the skin to heal. In some cases, blisters may become filled with pus if infected. Foot blisters can be more than bothersome. If this applies to you, it is suggested that you contact a podiatrist who can treat it safely, and offer effective blister prevention techniques.
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 Carolina Foot & Ankle Specialists. 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.

Athlete's Foot and and Why It Reoccurs

Athlete’s foot is a common fungal infection that affects the skin on the feet, particularly between the toes. It is caused by fungi known as dermatophytes, which thrive in warm, moist environments like sweaty socks and shoes. The symptoms of athlete's foot include itching, redness, peeling, and sometimes blistering or cracking of the skin. There are different types of athlete’s foot, including interdigital, which affects the spaces between the toes, and moccasin-type, which leads to dry, scaly skin on the soles and sides of the feet. The infection can reoccur because the fungi are resilient and can survive on contaminated surfaces like floors, towels, and shoes. Poor foot hygiene, wearing tight shoes, and exposure to communal areas like gym floors can contribute to repeated infections. Athlete’s foot can be uncomfortable. If you have developed this condition, it is suggested that you promptly schedule an appointment with a podiatrist who can offer prescribed medication for relief.

What Is Athlete’s Foot?
Tinea pedis, more commonly known as athlete’s foot, is a non-serious and common fungal infection of the foot. Athlete’s foot is contagious and can be contracted by touching someone who has it or infected surfaces. The most common places contaminated by it are public showers, locker rooms, and swimming pools. Once contracted, it grows on feet that are left inside moist, dark, and warm shoes and socks.
Prevention
The most effective ways to prevent athlete’s foot include:
- Thoroughly washing and drying feet
- Avoid going barefoot in locker rooms and public showers
- Using shower shoes in public showers
- Wearing socks that allow the feet to breathe
- Changing socks and shoes frequently if you sweat a lot
Symptoms
Athlete’s foot initially occurs as a rash between the toes. However, if left undiagnosed, it can spread to the sides and bottom of the feet, toenails, and if touched by hand, the hands themselves. Symptoms include:
- Redness
- Burning
- Itching
- Scaly and peeling skin
Diagnosis and Treatment
Diagnosis is quick and easy. Skin samples will be taken and either viewed under a microscope or sent to a lab for testing. Sometimes, a podiatrist can diagnose it based on simply looking at it. Once confirmed, treatment options include oral and topical antifungal medications.

Types of Edema and Their Impact on the Feet

Edema refers to the accumulation of excess fluid in the body’s tissues, leading to swelling. There are several types of edema, each with distinct causes and effects. Idiopathic edema is a condition where swelling occurs without any clear underlying medical cause, often affecting the feet and ankles. Pulmonary edema occurs when fluid builds up in the lungs, but it can also cause swelling in the feet and ankles as the body struggles to manage fluid balance. Lymphoedema, on the other hand, results from a blockage in the lymphatic system, leading to fluid retention and swelling, commonly in the legs and feet. In all cases, edema can cause discomfort, restricted movement, and skin changes in the affected areas. If you have swollen feet or ankles, it is suggested that you are under the care of a podiatrist who can help you manage this condition.
Swollen feet can be a sign of an underlying condition. If you have any concerns, contact one of our podiatrists of Carolina Foot & Ankle Specialists. Our doctors can provide the care you need to keep you pain-free and on your feet.
Swollen feet are a common ailment among pregnant women and people who stand or sit for extended periods. Aging may increase the possibility of swollen feet and patients who are obese often notice when their feet are swelling too. There may be medical reasons why swollen feet occur:
- Phlebitis - A condition that causes the veins to become inflamed and can also cause leg pain.
- Liver disease - This may lead to low blood levels of albumin which is a protein. This can cause fluid in the blood to pass into the tissues and several areas of the body can become swollen.
- Heart failure - When the heart doesn’t pump properly the blood that is normally pumped back to the heart can pool in the veins of the legs causing swollen feet.
- Kidney disease - One of the main functions of the kidneys is releasing excess fluid in the body. This type of condition can make it difficult for the kidneys to function properly, and as a result the feet may become swollen.
- Deep-vein thrombosis (DVT)- This is a serious condition where blood clots form in the veins of the legs. They can block the return of blood from the legs to the heart which may cause the feet to swell. It is important to be treated by a podiatrist if this condition is present.
Swollen feet can also be caused by bone and tendon conditions, including fractures, arthritis, and tendinitis. Additionally, there may be skin and toenail conditions and an infection may cause the feet to swell. Patients who take medicine to treat high blood pressure may be prone to getting swollen feet.
Many patients elevate their feet to help relieve the swelling and this is generally a temporary remedy. When a podiatrist is consulted the reason behind the swelling can be uncovered and subsequently treated.

Managing Diabetic Foot Ulcers

A diabetic foot ulcer is an open wound or sore that develops on the feet of individuals with diabetes. High blood sugar levels can damage nerves and blood vessels, leading to reduced sensation and poor circulation, which makes it harder for wounds to heal. Symptoms include redness, swelling, pain, and sometimes drainage or foul odor. Proper treatment is essential to prevent complications, such as infections or even amputation. Early care includes cleaning the ulcer, applying topical medications, and wearing special footwear to reduce pressure. In more severe cases, debridement, which is the removal of dead tissue, or surgery, may be necessary. A podiatrist plays a critical role in treating diabetic foot ulcers by providing wound care, recommending custom footwear, and monitoring the healing process. If you have diabetes and notice any foot sores or ulcers, it is suggested that you promptly schedule an appointment with a podiatrist to prevent serious complications.
Diabetic foot care is important in preventing foot ailments such as ulcers. If you are suffering from diabetes or have any other concerns about your feet, contact one of our podiatrists from Carolina Foot & Ankle Specialists. Our doctors can provide the care you need to keep you pain-free and on your feet.

The Importance of Caring for Your Feet
