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.  

Diabetes is the condition in which the body does not properly process food for use as energy. People with Type 1 diabetes cannot produce insulin, which is required for glucose to feed your body’s cells. It is typically caused by the immune system mistaking healthy cells for foreign invaders and destroying the insulin-producing cells in the pancreas. On the other hand, people with Type 2 diabetes cannot respond to insulin properly, and eventually cannot produce enough.  The Centers for Disease Control and Prevention reports that over 30 million people in the United States have diabetes, with 1 in 4 having no idea they have it. Surprisingly, diabetes is the seventh leading cause of death in the US. The symptoms of diabetes include frequent urination, fatigue, hunger, and even blurry vision.

Diabetes can also affect the feet as well. Over time, diabetes can cause nerve damage to your feet, which could then lead to symptoms such as tingling, pain and numbness in the feet. Neuropathy can be very dangerous to a person with diabetes, since it prevents them from feeling injuries such as cuts or blisters in the feet, and if not detected early enough, may lead to infection. Neuropathy can also lead changes in the shape of your feet and toes. The best way for people with diabetes to prevent or delay neuropathy is keeping their blood glucose levels in their target range. This consists of eating right, having the correct amount of exercise, and taking medications.

Diabetes can also create calluses and foot ulcers as well. Calluses build up faster and occur more frequently with those affected by diabetes. If there are too many calluses, therapeutic shoes and inserts may be required. It is important to have calluses trimmed by a health professional, as doing it yourself may lead to infections. If these calluses continue to develop and thicken, they can lead to foot ulcers. Foot ulcers are open sores, that appear on the ball of the foot or on the bottom of the big toe. These ulcers can lead to future infections if not treated and may possibly result in losing a limb. It is important to report any ulcers to your podiatrist right away. Your doctor may take x-rays to examine the foot and clean out any dead and infected tissue.

Lastly, diabetes can also lead to poor circulation and peripheral arterial disease (PAD). The poor circulation in the feet and leg area is a result of diabetes narrowing and hardening, eventually slowing down the blood flow in that area. The best way to prevent this is to keep away from smoking and follow your doctor’s advice for maintaining blood pressure and cholesterol. PAD is similar to this complication. PAD is when blood vessels narrow or are blocked by fatty deposits. PAD also increases your risk of heart attacks and strokes and is a common condition to those affected by diabetes. The combination of both PAD and neuropathy may lead to infections and can result in amputation of certain limbs. PAD can be prevented with wearing the proper foot wear and regularly taking care of your feet.

If you want to take care of your feet, you should wash and dry them carefully and perform daily inspections to check for cuts, blisters, or swelling. Any physical activity you partake in should be approved by your health care provider. You should also be sure to wear special shoes if advised to do so by your doctor.

Podiatry is a branch of medicine that deals with the study, diagnosis, and treatment of foot and ankle conditions. There are various subdivisions in podiatry; biomechanics is one of them. Biomechanics is the way in which the bones, muscles, and joints of the feet and lower limb interact with each other.

Our feet play crucial roles in the way we move, and it is rare to have feet that are completely symmetrical. Common biomechanical issues include high or low arches or uneven leg heights. Excessive pronation often leads to fallen arches, or flat feet, and is a common cause of running injuries. People whose feet are over-pronated tend to have flexible and unstable feet. Pain is usually experienced during walking and running.

At times, people may be able to adapt to these abnormalities without any difficulties, but in other cases, these issues can cause a great deal of pain. This pain occurs because the joints, muscles, ligaments, and tendons are put under an excess amount of stress during movement. Common symptoms of biomechanical problems stemming from the feet include hip pain, knee pain, leg cramps, ankle pain, lower back pain, weak ankles, tripping, heel pain, Achilles pain, and shin splints.

Many biomechanical issues can be treated with orthotics. Orthotics are shoe insoles that are used to help control the way the foot operates.  They can provide relief from foot pain, heel pain, and knee pain. Depending on your specific case, you may need to purchase over-the-counter orthotics or custom orthotics to fit your feet. Your podiatrist will be able to prescribe the perfect orthotic for your feet to help you walk around with ease.

Gait is defined as the way we move our bodies from one point to another. This is usually done by either walking or running. Gait analysis is a method used to assess the way we walk or run to highlight biomechanical abnormalities. Gait analyses are a great way to take a detailed look at how you walk and how your foot moves while you walk. An examination of the feet will help your podiatrist understand why you are suffering pain in other parts of your body.

Toe pain can originate from corns, calluses, hammertoes, and bunions, as well as ingrown toenails, sprains, fractures, and dislocations. Corns develop as the toe rubs against the inside of a shoe which causes the skin to thicken as a form of protection. A corn is typically cone-shaped and has a small, hardened spot that points inward. When a corn is pressed into the skin, the toe becomes painful. Corns usually form on the top or side of the toe. A callus is also a thickened patch of skin that generally forms on the bottom of the foot. Calluses are the result of friction from the toe rubbing against the inside of a shoe. They may also occur by walking barefoot or having flat feet. A hammertoe is a bump on the knuckle of the second toe that is produced by wearing shoes that are too short for your feet. The bony protrusion rubs against the top of the shoe causing pain and irritation. A bunion is a malformation of the big toe. The base of the big toe pushes away from the smaller toes, forcing the top of the big toe to press toward the other toes. Bunions can be hereditary, or they can result from injury to the toe joint or from wearing high heels with a narrow toe box. The toe becomes inflamed, and a bump may develop at the end of the misplaced bone. Ingrown toenails typically affect the big toe and its surrounding skin. The nail will dig into the skin and become painful. Wearing tight or narrow shoes that compress the big toe causes the nail to grow into the fleshy part of the toe. Cutting toenails incorrectly can also add to the development of an ingrown toenail. A toe sprain originates from a torn or stretched ligament. Strapping the injured toe to the toe next to it for stabilization is common. A broken or fractured toe usually occurs from trauma like dropping a heavy object on it or bumping into something extremely hard and rigid. Osteoporosis, a thinning of the bones, can also bring about toe fractures. 

Any of the conditions mentioned can lead to pain and irritation. While some are more serious than others, seeking an examination and diagnosis from a podiatrist is a good idea. A podiatrist can treat each ailment and get you back on your feet again without pain.
