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.

Neuropathy is the weakness, numbness, and pain in the hands and feet due to damage to the peripheral nerves. The peripheral nerves are responsible for sending information from the brain and spinal cord to the rest of your body. Causes of Neuropathy include: traumatic injuries, infections, metabolic problems, exposure to toxins, and diabetes.

Diabetes is the most common cause, with more than half of the diabetic population developing some type of neuropathy. There are several types of neuropathy and they vary based on the damage of the nerves. Mononeuropathy is classified as only one nerve being damaged. When multiple nerves are affected, it is referred as polyneuropathy. One of the types of polyneuropathy is distal symmetric polyneuropathy. It is the most common for people with diabetes and starts when the nerves furthest away from the central nervous begin to malfunction. The symptoms begin with pain and numbness in the feet and then they travel up to the legs. A rarer form of polyneuropathy is acute symmetrical peripheral neuropathy, which is a severe type that affects nerves throughout the body and is highly associated with Guillain-Barre syndrome, an autoimmune disorder that attacks the peripheral nervous system and can be fatal. Although there are many types of neuropathy, most of them share the same symptoms such as pain, extreme sensitivity to touch, lack of coordination, muscle weakness, dizziness, and digestive problems. Since neuropathy affects the nerves, those affected should be careful of burns, infection and falling, as depleted sensations disguise such ailments.

The best way to prevent neuropathy is to manage any medical conditions such as diabetes, alcoholism, or rheumatoid arthritis. Creating and managing a healthy lifestyle can also go a long way. Having a healthy diet full of fruits, vegetables, whole grains and lean protein can keep the nerves healthy. These types of food have the nutrients to prevent neuropathy. Regularly exercising can help as well, but it is best to consult with a doctor about the right amount. In addition to diet and exercise, avoiding risk factors will also prevent neuropathy. This includes repetitive motions, cramped positions, exposure to toxic chemicals, smoking and overindulging on alcohol.

The human foot has 26 different bones, and the foot is divided into three parts: the hindfoot, the midfoot, and the forefoot. Each section of the foot is composed of a different amount of bones. For instance, the forefoot is made up of 19 bones. The midfoot is composed of five smaller bones called the navicular, cuboid, and three cuneiform bones. Lastly, the hindfoot is made up of only the talus and the calcaneus. The feet tend to be vulnerable to slipping and twisting; consequently, fractured bones within the foot are common. When a bone gets crushed, bent, twisted, or stretched it may become broken.

Many foot fractures occur through an accident or trauma. More specifically, common causes for broken feet are car accidents, falls, missteps, or overuse. If you have a broken ankle or foot, you may have one or more of the following symptoms: throbbing pain, swelling, bruising, tenderness, deformities, and difficulty walking.

There are some factors that may put you at a higher risk of developing a broken foot. People who participate in high-impact sports are more likely to develop foot fractures because of the stresses, direct blows, and twisting injuries involved in gameplay. Additionally, those who suddenly increase their activity level are more likely to suffer a stress fracture.

Unfortunately, there are different complications that may arise because of a foot fracture. For instance, arthritis may be caused by fractures that extend into the joints. Bone infections are also possible in open fractures due to the bone being exposed to bacteria. However, there are ways you can help prevent yourself from breaking your foot. One way to avoid fractures is to wear proper footwear. If you plan on going on a run, you should wear running shoes. You should also replace your shoes if you notice that they are becoming worn out. For runners, it is best to replace shoes every 300 to 400 miles.

Treatment for foot fractures usually consists of rest, ice, elevation, and compression (RICE). If you plan on wrapping your foot, try not to wrap it too tightly because doing so may cut off blood supply in the foot. You should also avoid walking on the fractured foot.

If you suspect you have a broken foot, you should see your podiatrist right away. It is important that you have someone bring you to your doctor, since driving with a broken foot can be dangerous. You should especially seek urgent care if you are experiencing numbness, pain, or deformities in your foot.

Cracked heels can make life very frustrating and embarrassing when displaying the bare feet. Aside from being unpleasing to the eye, they can also tear stockings and socks and wear out shoes at a faster rate. When severe, cracked heels may cause pain or infection.

Cracked heels are a problem for those who are athletic, those who may walk a lot, and those who have especially dry skin. Those who use medication that dry the skin, those who swim often, wearing certain types of shoes, and those who are diabetic may have trouble with cracked heels. Seniors whose skin produces less oil may also have trouble with cracked feet. There is no one way to develop cracked feet, and there is no cure.

Today, the market consists of numerous products that have a variety of ingredients to promote healing. Some of these are over-the-counter. Others are prescribed by a doctor, especially for those who have chronic dry feet and heels.

Some doctors recommend wearing socks at night for those with rough skin. This helps further healing, and helps creams stay on longer and better absorb into the skin.

One way to alleviate dryness that causes cracked heels is by using moisturizers both day and night. Another way is to make sure the skin is clean and dry at all times. Using a pumice stone to buff away dead skin before putting on moisturizer can also help. Cracked heels will not respond to the cream unless the outer layer of skin is first removed through exfoliation. After exfoliation, lotion or ointment will be absorbed by the skin more easily.

Foods that produce healing and balance can also help the skin from within. Everything that is put into the body can either help it or hurt it. Taking supplements of omega-3 fatty acids and zinc can also be very beneficial.

Nevertheless, not all products are guaranteed to help treat cracked feet. Seeing a professional is best if other treatments options were unsuccessful. A podiatrist should be able to give the best advice to help with this problem.

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.
