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.

Hammertoes are painful deformities that frequently form on the second, third, or fourth toe. The condition is often caused by an issue in foot mechanics. This can be caused by the person’s specific gait or the manner in which they walk, or by shoes that do not comfortably fit the deformity.  Hammertoes can be formed after wearing shoes that are too narrow or short for the foot or have excessively high heels. Shoes that are not properly sized will force the toes into a bent position for long periods of time. This can cause the muscles to shorten and toes to bend into the deformity of a hammertoe.

Hammertoe can also be caused by complications from rheumatoid arthritis, osteoarthritis, trauma to the foot, heredity, or a cerebral vascular accident. Pain and difficult mobility of the toes, deformities, calluses, and corns are all symptoms of a hammertoe.

Someone who suspects they have the symptoms of a hammertoe should consult with a physician—particularly a podiatrist. Podiatrists diagnose and treat complications of the foot and ankle. If the podiatrist discovers that the affected toes are still flexible, treatment for the hammertoe may simply involve exercise, physical therapy, and better-fitting shoes. Treatment for hammertoes typically involves controlling foot mechanics, such as walking, through the use of customized orthotics.

For more serious cases in which the toes have become inflexible and rigid, surgery may be suggested. During the operation, the toe would receive an incision to relieve pressure on the tendons. A re-alignment of the tendons may then be performed by removing small pieces of bone to straighten the toe. In some cases, the insertion of pins is needed to keep the bones in the proper position as the toe heals. The patient is usually allowed to return home on the same day as the surgery.

If surgery is performed to repair a hammertoe, following the postoperative directions of your doctor is essential. Directions may include several stretches, picking up marbles with your toes, or attempting to crumple a towel placed flat against your feet. Wear shoes that have low heels and a wide amount of toe space to maintain comfort. Closed-toe shoes and high heels should be avoided. Shoes with laces allow the wearer to adjust how fitted he or she may want the shoes to be and also allow for greater comfort. To provide adequate space for your toes, select shoes that have a minimum of one-half inch of space between the tip of your longest toe and the inside of the shoe. This will also relieve pressure on your toes and prevent future hammertoes from forming.

Other preventative measures that can be taken include going shopping for new shoes in the middle of the day. Your feet are its smallest in the morning and swell as the day progresses. Trying on and purchasing new shoes midday will give you the most reliable size. Be sure to check that the shoes you purchase are both the same size. If possible, ask the store to stretch out the shoes at its painful points to allow for optimum comfort.  

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 branch of medicine that is focused on the treatment, diagnosis, and study of disorders of the lower leg, ankle and foot is referred to as podiatry. Because people often spend a great deal of their time on their feet, many problems in this area can occur. A person seeks help from the field of podiatry when they need treatment for heel spurs, bunions, arch problems, deformities, ingrown toenails, corns, foot and ankle problems, infections, and problems with the foot that are related to diabetes and additional diseases.

To treat problems of the foot, ankle or lower leg, a podiatrist may prescribe physical therapy, drugs, perform surgery, or set fractures. Individuals may also be recommended to wear corrective shoe inserts, custom-made shoes, plaster casts and strappings in order to correct deformities.

When trying to gather information on a patient problem, a scanner or force plate may be used in order to design orthotics. During this procedure, patients are told to walk across a plate that is connected to a computer; the computer then takes a scan of the foot and indicates weight distribution and pressure points. The computer readouts will give the podiatrist information to help them determine the correct treatment plans.

Diagnosis is also provided through laboratory tests and x-rays. Through the foot, the first signs of serious problems such as heart disease, diabetes and arthritis can show up. For example, individuals that have diabetes may frequently have problems such as infections and foot ulcers because they experience poor circulation in the foot area. A podiatrist can then have consultations with patients when symptoms arise. Referrals will then be made to specialists that handle the greater health problems.

Some podiatrists have their own independent, private practices or clinics where they have a small staff and administrative personnel. Many podiatrists work within group practices. They usually spend time performing surgery in ambulatory surgical centers or hospitals, or visit patients in nursing homes. Podiatrists typically spend between 30 to 60 hours of week working. Some podiatrists specialize in public health, orthopedics, surgery, or primary care. Other fields include specialties in geriatrics, dermatology, pediatrics, diabetic foot care and sports medicine.

Some podiatrist specialists complete extra training in the area of foot and ankle reconstruction that results from the effects of physical trauma or diabetes. There are also surgeons that perform surgery of a cosmetic nature to correct bunions and hammertoes.

Heel spurs are calcium deposits that cause bone protrusions on the heel bone. Heel spurs are usually associated with plantar fasciitis, which occurs when the plantar fasciitis in the foot becomes inflamed. Typically, heel spurs don’t cause any symptoms. However, they can produce chronic or intermittent heel pain. Those who have had the condition often describe the irritation as a stabbing pain.

There are risk factors that may make you more likely to develop heel spurs. People who have abnormal walking gaits, run and jog on hard surfaces, are obese, or wear poorly fitting shoes are more likely to develop heel spurs.

Fortunately, there are precautions you can take to avoid developing heel spurs. One of the best ways to do this is by wearing well-fitting shoes with shock-absorbent soles. Another preventative technique is to choose running shoes if you plan on running, and walking shoes if you plan on walking. Shoes are made for different activities and it is important to research a shoe before you purchase a pair.

The pain associated with heel spurs often decreases the more you walk. However, a recurrence of pain after an extended period of rest or walking is likely to occur with this condition. Those with severe heel spur pain may opt to go the surgical route for treatment.  However, more than 90% of those with the condition get better without surgical treatment. If you have a heel spur and want to know if surgery is right for you, you should go to your podiatrist and he or she will be able to conduct a pre-surgical test or exam to determine if you are an optimal candidate for surgery.
