The Achilles tendon is the strongest tendon in the human body. Its purpose is to connect the lower leg muscles and calf to the heel of the foot. This tendon is responsible for facilitating all types of movement, like walking and running. This tendon provides an enormous amount of mobility for the body. Any injuries inflicted to this tissue should be immediately brought up with a physician to prevent further damage. 

The most common injuries that can trouble the Achilles tendon are tendon ruptures and Achilles tendinitis. Achilles tendinitis is the milder of the two injuries. It can be recognized by the following symptoms: inflammation, dull-to-severe pain, increased blood flow to the tendon, thickening of the tendon, and slower movement time. Tendinitis can be treated via several methods and is often diagnosed by an MRI. 

An Achilles tendon rupture is trickier to heal, and is by far the most painful injury. It is caused by the tendon ripping or completely snapping. The results are immediate and absolutely devastating, and will render the patient immobile. If a rupture or tear occurs, operative and non-operative methods are available. Once the treatment begins, depending on the severity of the injury, recovery time for these types of issues can take up to a year. 

Simple preventative measures can be taken as a means to avoid both injuries. Prior to any movement, taking a few minutes to stretch out the tendon is a great way to stimulate the tissue. Calf raises, squats, leg curls, leg extensions, leg raises, lunges, and leg presses are all suggested ways to help strengthen the lower legs and promote Achilles tendon health. 

Many problems arise among athletes and people who overexert themselves while exercising. Problems can also happen among those who do not warm up properly before beginning an activity. Proper, comfortable shoes that fit correctly can also decrease tendon injuries. Some professionals also suggest that when exercising, you should make sure that the floor you are on is cushioned or has a mat. This will relieve pressure on the heels. A healthy diet will also increase tendon health. 

It is very important to seek out a podiatrist if you believe you have an injury in the Achilles region. Further damage could result in severe complications that would make being mobile difficult, if not impossible.

Tarsal tunnel syndrome is a condition in which there is a compression of the posterior tibial nerve. The posterior tibial nerve runs along the inside of the ankle into the foot. Tarsal tunnel syndrome is named for the tarsal tunnel, which is a thin space along the inside of the ankle beside the ankle bones. This space contains various nerves, arteries, and tendons, and includes the posterior tibial nerve. The tibial nerve is the peripheral nerve in the leg responsible for sensation and movement of the foot and calf muscles. In tarsal tunnel syndrome the tibial nerve is compressed, causing tingling or burning, numbness, and pain.

Common causes of tarsal tunnel syndrome involve pressure or an injury. Injuries that produce inflammation and swelling in or around the tunnel may place pressure on the posterior tibial nerve. Direct pressure on the tibial nerve for an extended period of time, sometimes caused by other body structures close by or trauma to the tibial nerve, can result in tarsal tunnel syndrome. Diseases that damage nerves, such as diabetes or arthritis, may cause tarsal tunnel syndrome. Those with flat feet are at risk for developing the condition, as the extra pressure and strain placed on the foot may compress the posterior tibial nerve.

Feeling different sensations in the foot at different times is a common symptom of tarsal tunnel syndrome. An afflicted person may experience pain, tingling, burning or other unusual sensations in the foot of the affected leg. Symptoms are primarily felt on bottom of the foot and/or the inside of the ankle. Symptoms can appear suddenly and may occur due to overuse of the foot.

To diagnose tarsal tunnel syndrome, your podiatrist may examine the foot and tap the posterior tibial nerve to see if symptoms surface. He or she may also order an MRI to determine if a mass is present.

Treating tarsal tunnel syndrome will depend on the decision of your podiatrist. Multiple options are available, however, and can include rest, ice, immobilization, oral medications such as anti-inflammatory drugs (NSAIDS), physical therapy, injection therapy, orthotics, supportive shoes, braces, and surgery.

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.  

An ingrown toenail is a nail that has curved downward and grown into the skin.  This typically occurs at either the nail borders or the sides of the nail.  As a result, pain, redness, swelling, and warmth may occur in the toe.  If a break in the skin forms due to the ingrown nail, bacteria may enter and cause an infection in the area; this is typically characterized by a foul odor and drainage.

Ingrown toenails have multiple reasons for developing.  In many instances, the condition is a result of genetics and is inherited.  The most common cause, however, is improper trimming; cutting the toenails too short forces the skin beside the nail to fold over.  An ingrown toenail can also develop due to trauma, such as stubbing the toe, having an object fall on the toe, or participating in activities that involve repeated kicking or running.  Wearing shoes that are too tight or too short can also cause ingrown toenails.

Treatment for an ingrown toenail varies between patients and the severity of the condition.  In most cases, it is best to see your podiatrist for thorough and proper treatment.  After examining your toe, your podiatrist may prescribe oral antibiotics to clear the infection if one is present.  Surgical removal of either a portion of the nail or the entire nail may also be considered.  In some cases, complete removal or destruction of the nail root may be required.  Most patients who undergo nail surgery experience minimal pain afterward and can return to normal activity the following day.

Ingrown toenails can be prevented with proper nail trimming and by avoiding improper-fitting shoes.  When cutting the toenails, be sure that you are cutting in a straight line and avoid cutting them too short.  Shoes should not be too short or tight in the toe box.

Blisters are pockets of fluid that occur under the top layer of your skin. These fluid pockets are usually filled with pus, blood, or serum. Blisters may itch or hurt and can appear as a single bubble or in clusters.

The most common types of blisters are friction blisters. This type of blister may be caused by wearing shoes that are too tight. Friction blisters can also occur on the hands. A change in temperature may also cause blisters on the feet. In the freezing air, frostbite on your toes can lead to blisters, as well as sunburn from hot weather.

The best way to treat a blister is to keep it clean and dry. Most blisters will get better on their own. Once the skin absorbs the fluid within the blister, it will flatten and eventually peel off. You should avoid popping your blister unless you podiatrist does it for you. Additional treatment options include applying an ice pack to the blister or using over-the-counter blister bandages to cover the affected area.

If your blister becomes discolored, inflamed, or worsens it is advised that you speak to your podiatrist. Blisters that are yellow, green, or purple may be infected and require immediate medical attention. Blisters that are abnormally colored may be a sign of a more serious underlying health condition such as herpes.

Flatfoot is a foot disorder that is not as straightforward as many people believe.  Various types of flatfoot exist, each with their own varying deformities and symptoms.  The partial or total collapse of the arch, however, is a characteristic common to all types of flatfoot.  Other signs of flatfoot include:

• “Toe drift,” or the pointing outward of the toes and the front part of the foot
• The tilting outward of the heel and the tilting inward of the ankle
• The lifting of the heel off the ground earlier when walking due to a tight Achilles tendon
• Hammertoes
• Bunions

One of the most common types of flatfoot is flexible flatfoot.  This variation usually starts in childhood and progresses as one ages into adulthood.  Flexible flatfoot presents as a foot that is flat when standing, or weight-bearing.  When not standing, the arch returns.  Symptoms of flexible flatfoot include:

• Pain located in the heel, arch, ankle, or along the outside of the foot
• Overpronation, or an ankle that rolls in
• Shin splint, or pain along the shin bone
• General foot aches or fatigue
• Pain located in the lower back, hip, or knee

Your podiatrist will most likely diagnose flatfoot by examining your feet when you stand and sit.  X-rays may be taken to define the severity and help determine the treatment option best for your condition.  Nonsurgical treatments can include activity modification, weight loss, orthotics, immobilization, medications, physical therapy, shoe modifications, and ankle foot orthoses (AFO) devices.  If nonsurgical methods prove ineffective, surgery may be considered.  Multiple surgical procedures can correct flatfoot; and depending on your specific condition, one may be selected alone or combined with other techniques to ensure optimal results.
