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.

Diabetics must be wary of all wounds, regardless of depth or size. Diabetes, a chronic disease in which the body cannot properly use glucose the way it normally would, causes various complications that make wounds difficult to heal. Nerve damage or neuropathy will cause diabetics to have trouble feeling the pain of a blister or cut until the condition has significantly worsened or become infected. A diabetic’s weakened immune system can make even the most minor of wounds easily susceptible to infection. Diabetics are also more prone to developing narrow, clogged arteries, and are therefore more likely to develop wounds.

Wounds should be taken care of immediately after discovery, as even the smallest of wounds can become infected if enough bacteria build up within the wound.  To remove dirt, wounds should be first rinsed under running water only. Soap, hydrogen peroxide, or iodine can irritate the injury and should be avoided. To prevent infection, apply antibiotic ointment to the wound and cover it with a bandage. The bandage should be changed daily. The skin around the wound may be cleaned with soap.

To prevent further exacerbation, see a doctor—especially if you have diabetes. Minor skin conditions can become larger problems if not properly inspected. As the wound heals, make sure to avoid applying pressure to the affected area.

Fungal infection of the toenail, or onychomycosis, typically appears as a gradual change in a toenail’s texture and color that involves brittleness and darkening.  The fungal infection itself occurs beneath the surface of the nail.  Aside from discoloration, other symptoms include the collection of debris beneath the nail plate, white marks on the nail plate, and a foul odor emanating from the nail.  If ignored, the infection can spread into other nails and the skin; in severe cases, it can hinder one’s ability to work or walk. 

The toenails are particularly vulnerable to contracting infection in moist environments where people are likely to be walking barefoot, such as around swimming pools, public showers, and locker rooms.  Fungal infection may also be more likely to occur in nail beds that have been injured, and sufferers of chronic diseases such as diabetes, circulatory problems, or immunodeficiency conditions are particularly prone to developing fungal nails. 

Fungal nails can be primarily prevented by practicing proper hygiene and regularly examining the feet and toes.  Carefully washing the feet with soap and water and thoroughly drying the feet afterwards are essential.  Other tips include wearing shower shoes in public areas, changing shoes and socks daily, keeping toenails clipped at a short length, wearing breathable shoes that fit properly, wearing moisture-wicking socks, and disinfecting home pedicure tools and instruments used to cut nails.

Fungal nail treatment may vary between patients and the severity of the condition.  Your podiatrist may suggest a daily routine of cleansing that spans over a period of time to ease mild infections.  Over-the-counter or prescription antifungal agents may also be prescribed, including topical and/or oral medications.  Debridement, or the removal of diseased nail matter and debris, may also be performed.  In more severe cases, surgical treatment may be needed.  In some instances, the temporary removal of the fungal nail allows for the direct application of a topical antifungal to the nail bed.  In other cases, a chronically painful fungal nail that has not responded to other treatments may be permanently removed; this allows the infection to be cured and avoids the growth of a deformed nail.  

The ankle joint is the point at which the bones of the leg and foot join. This joint is crucial because it is responsible for the foot’s mobility. Ankle pain is typically the result of inflammation from an injury to bones, joint space, cartilage, ligaments, tendons, or muscles in the area. Commonly associated symptoms with ankle pain are bruising, redness, numbness, stiffness, weakness, and tingling.

The most common causes of ankle pain are sprains and injuries. Ankle sprains are one of the most common musculoskeletal injuries. Sprains occur when the ligaments of the ankle become partially or completely torn due to sudden stretching. Sprains can occur on either the inner or outer sides of the ankle joint. Usually, these injuries occur when the ankle is twisted in an activity by stepping off an uneven surface. More specific causes include rheumatoid arthritis, gout, osteoarthritis, and Achilles tendonitis.

If you are experiencing ankle pain, you should consult with your podiatrist to choose the best method of care. Your doctor will conduct an examination of your ankle to determine the underlying cause of the pain.

Although walking shoes and running shoes look similar, they have characteristics that make them different from each other. Runners should avoid running in walking shoes and vice versa. It is very important that you wear the proper footwear for the activity you are going to partake in, for you to avoid injury.

If you are looking to buy a new pair of running shoes, there are certain things you should look out for. One of the main components that makes up a good running shoe is flexibility. You should be able to bend and flex the forefoot of the shoe that you are purchasing. If you can bend the entire shoe in half with ease, this is a sign that the shoe does not have enough structure for your feet. Another feature you should look for is a low heel. Certain running shoes have a low heel to support runners who land on the ball of their feet. Lastly, you should look for the fit of the running shoe. You should visit the best running shoe store in your area to have your feet properly sized for the shoes in the store. Usually, the staff will be able to help recommend the best type of running shoe for your needs.

When you are walking, the body’s weight is evenly distributed on the foot. This influences the design of shoes made for walking. If you are looking to buy a pair of walking shoes, there are different features you should look for to determine which pair of shoes is best for you. Walking shoes should be flexible through the ball of the foot to allow for a greater range of motion through the roll of the forefoot. These shoes also should have greater arch support for the foot. If you plan on walking long distances or on hard surfaces, it is best that you wear shoes that have cushioning.

When trying on a new pair of shoes, the heel should fit snugly without slip. You should shop for shoes after a long walk, since your feet tend to swell throughout the day. Many people have one foot that is a different size than the other, so it is best that you have both feet measured when looking for your true size. You should also beware that sizes vary depending on the shoe brand. A certain size in one brand may be a different size in a different brand. Lastly, you should always walk around in shoes that you plan on buying. This will help you determine whether the shoes are comfortable and if they fit well on your feet.

Always look for good shoe construction when shopping for new sneakers. The upper part of the shoe should allow for adjustment through laces or straps. If you need help with shoe sizing or if you need custom orthotics for your feet, you should make an appointment with your podiatrist for assistance. He or she will be more than happy to help you with your shoe sizing needs.  

There are many reasons why patients experience swelling of the feet. It is rather common and may be a side effect of pregnancy or from sitting and standing for most of the day. Gravity could also play a role in the development of swollen feet. It is known that the weight of blood volume in our bodies is exerted on the veins in the legs and feet. The veins may not work as efficiently during the aging process, and this could make the blood flow backward causing swollen feet. Relief may be found when obese patients lose weight, and it may help to engage in compression therapy by wearing compression socks, stockings, or athletic sleeves. This method can release pressure on the feet and ankles which may help to reduce existing swelling. There are patients who have controlled their swollen feet by implementing healthy lifestyle changes. These can consist of reducing salt intake, incorporating a gentle exercise regime into the daily routine, and drinking plenty of fresh water. Swollen feet may be a temporary condition that affects people who travel via airplane or automobile, so it is beneficial to walk as frequently as possible even though it can be difficult. Swelling of the feet can also be indicative of other health issues so it is important to pay attention to any type of chest pain, mental confusion, dizziness, or fever. If you consistently have swollen feet, it is strongly suggested that you consult with a podiatrist who can help determine the cause and how to effectively treat it.
