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.

Each foot, on average, has about 250,000 eccrine sweat glands that produce half a pint of sweat each day. Sweating is a natural and important bodily function. It regulates the body’s temperature by cooling the skin so that it does not overheat.  In individuals with hyperhidrosis, the sympathetic nervous system works in "overdrive", producing far more sweat than what is required. People with plantar hyperhidrosis experience an excess amount of sweat on their feet. It is estimated that 2% to 3% of all Americans suffer from some form of hyperhidrosis. This condition is often caused by neurologic, endocrine, infectious, and other systemic disease. Other factors that may trigger the condition are heat and emotions.

People with hyperhidrosis may notice an overabundance of sweat on their feet, along with a strong odor. The feet may also have a wet appearance coupled with infections such as athlete’s foot or toenail fungus. The sweat may even appear in low temperatures, such as during the winter months. People with plantar hyperhidrosis often need to change their socks several times throughout the day.

The specific cause of hyperhidrosis is unknown, and many believe it may be caused by over-activity. However, others believe the condition is genetic.  Caffeine and nicotine are known to cause excitement and nervousness which are two emotions that may make the condition worse.

If you are looking to treat your hyperhidrosis the most important thing you should do is wash your feet every day.  You may even need to wash your feet twice a day, if necessary.  You should also make sure you are wearing the right socks. Wool and cotton socks are both known to be good for ventilation, meaning they allow the feet to breathe. You should avoid socks made from nylon which trap moisture and lead to sogginess. Other common treatment options are over-the-counter antiperspirants that contain a low dose of metal salt.  In some cases, prescription strength antiperspirants that contain aluminum chloride hexahydrate may be necessary. In severe cases, surgery may be required.

Untreated hyperhidrosis can easily lead to complications.  Some complications that may arise from the disorder include nail infections, warts, and bacterial infections.  Consequently, it is important that you seek treatment from your podiatrist if you suspect that you may have plantar hyperhidrosis.

It is never normal for a child to experience pain in his or her feet. Foot pain that lasts more than a few days and limits a child’s ability to walk should be examined by a podiatrist. Many adult foot ailments originate in childhood and may be present at birth. Common foot issues that are experienced by children are pediatric flat foot, Sever’s disease, ingrown toenails, and plantar warts.

A child’s foot grows rapidly during the first year, allowing it to reach almost half of their adult foot size. Consequently, foot specialists consider the first year to be the most crucial point in the foot development process. There are ways you can help ensure that your child’s foot develops properly. One way is to carefully look at your baby’s feet. If you notice any deformities, you should immediately seek professional care. You should also loosely cover your child’s foot, since tight coverings may prevent movement and inhibit normal development. Another tip is to change the baby’s positioning throughout the day. If your baby lies down in one spot for too long, it may put an excess amount of strain on the feet and legs.

It is best that you try not to force a child to start walking. Children will begin to walk when they are both physically and emotionally capable to do so. You should also avoid comparing your child’s walking progress with other children because the age range for independent walking may range. When your child’s feet begin to develop, you may need to change both their shoe and sock size every few months to allow room for their feet to grow.

Kids are sometimes prone to splinters, cuts, and severe injuries because they tend to walk around barefoot. This also makes them more susceptible to developing plantar warts which is a condition caused by a virus that invades the sole of the foot through breaks in the skin. These ailments can be avoided by making sure your child wears shoes in unsanitary environments. You should also wash any minor cuts or scrapes on your child’s feet. It is a myth that exposure to fresh air will heal injuries; fresh air will only expose your child’s cuts to germs.

As a parent, you should ensure that your child’s feet are developing properly and are being properly maintained. Consequently, it is important that you perform routine inspections on his or her feet to detect any injuries or deformities in their early stages. Early detection and treatment will help to ensure that your child does not develop any serious foot conditions.

A podiatrist will be able to address a variety of rare foot conditions, particularly the ones that affect children. The most common are Kohler’s disease, Maffucci syndrome, and Freiberg’s disease. They can be properly diagnosed by having an X-ray taken, but in more serious cases an MRI may be needed. Kohler’s disease generally affects younger boys and bone deterioration may result from an interruption of blood supply. Children who have Kohler’s disease may find relief when the affected foot is rested, and a special boot is worn. Benign growths in the long bones of a child’s foot may lead to the development of bone lesions, and this is known as Maffucci syndrome. People who have this condition find mild relief when custom-made orthotics are worn. Freiberg’s disease targets the ball of the foot and can typically affect pre-teen and teenage girls. The metatarsal bone becomes deteriorated and flattened, and common symptoms include swelling and stiffness. A cast is often necessary to wear with this disease as it can help to reduce existing pain. Erythromelalgia is a rare foot condition, and its cause is unknown. Symptoms of this disease can include intense burning pain and the feet may appear red or feel warm. Relief may be found when the affected foot is immersed in ice water. It can also be beneficial to elevate the foot frequently. If your child complains of foot pain, it is strongly suggested that you consult with a podiatrist who can diagnose and treat rare foot conditions.
