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.

Ankles are joints that connect bones in the feet with bones in the lower leg. They are comprised of bones, ligaments, muscles, tendons, blood vessels, and nerves. The ankle joint allows the foot to move side-to-side, as well as up-and-down.

Ankle pain can be caused by a variety of conditions, but is most commonly due to soft tissue injuries such as ankle sprains and strains. 

An ankle sprain occurs when one or more of the strong ligaments that support and stabilize the ankle become overly stretched or even torn if the ankle rolls, turns, or twists awkwardly. Depending on the grade of sprain (mild-moderate-severe), there will be varying degrees of pain, swelling, and restricted range of motion, along with tenderness, bruising, and ankle instability. There may even be an audible popping noise at the moment of injury.

Ankle strains can sometimes produce similar symptoms of pain, swelling, and loss of motion, however, they are due to overly stretched muscles and tendons—not ligaments. Ankle strains may also cause muscle cramps in the feet, calves and shins.

Ankle fractures are another common source of ankle pain and occur one or more of the three bones in the ankle become fractured (broken). These breaks can be stress fractures (due to repetitive stress) or traumatic fractures (due to an acute injury). Depending on where and how severe the fracture is, symptoms can include pain and swelling that can sometimes spread up to the knee, bruising or discoloration, and an inability to bear weight. A visible deformity or exposed bone may occur in severe fractures.

Various forms of arthritis may also cause ankle pain. Rheumatoid arthritis (RA) causes the immune system to attack healthy joints, like the ankle joint, by mistake, causing stiffness and swelling in both ankles. Osteoarthritis occurs when cartilage covering the ends of bones wears down, causing the bones to rub against each other. This results in pain, stiffness, and reduced range of motion in the ankle. Gout is a form of arthritis where excess amounts of uric acid in the bloodstream crystallize and build up on joints, causing severe pain and swelling. Reactive arthritis causes joint pain and swelling in the ankle in response to an infection in another part of the body.

Other forms of ankle pain include bursitis (an inflammation of a cushioning bursa sac between tendons and bone), scleroderma (a thickening of connective tissues), chronic ankle instability (caused by improperly healed ankle sprains), Achilles tendon injuries, flat feet, or an infection in the ankle.

The feet, being the foundation of the body, carry all of the body’s weight and are therefore prone to experiencing pain and discomfort. If you are experiencing foot pain, it is important to determine where in the foot you are experiencing this pain to help discover the cause of it. While pain can be experienced virtually anywhere in the foot, the most common sites of foot pain are in the heel and ankle.   

Heel pain can be due to a multitude of conditions including plantar fasciitis, Achilles tendinitis, and heel spurs. Pain experienced in the ankle can be a sign of an ankle sprain, arthritis, gout, ankle instability, ankle fracture, or nerve compression. In more serious cases, pain in the foot can be a sign of improper alignment or an infection.

Foot pain can be accompanied by symptoms including redness, swelling, stiffness and warmth in the affected area. Whether the pain can be described as sharp or dull depends on the foot condition behind it. It is important to visit your local podiatrist if your foot pain and its accompanying symptoms persist and do not improve over time.

Depending on the location and condition of your foot pain, your podiatrist may prescribe certain treatments. These treatments can include but are not limited to prescription or over-the-counter drugs and medications, certain therapies, cortisone injections, or surgery.

If you are experiencing persistent foot pain, it is important to consult with your foot and ankle doctor to determine the cause and location. He or she will then prescribe the best treatment for you. While milder cases of foot pain may respond well to rest and at-home treatments, more serious cases may take some time to fully recover.

An ingrown toenail is a nail that has curved downward and grows into the skin.  This typically occurs at 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.  Milder cases that don’t involve infection or other medical conditions can benefit from soaking the feet in room-temperature water and gently massaging the side of the nail.  In most cases, however, 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.

Foot and ankle injuries are common among athletes and those who exercise frequently. Most of these injuries are non-life-threatening and can heal in weeks with proper treatment and care. Serious injuries, however, require urgent medical treatment.

Common minor injuries include ankle sprains, ankle strains, Achilles tendonitis, plantar fasciitis, stress fractures, and turf toe. An ankle sprain is when the ligaments in the ankle have either become stretched or torn. When the muscle or tendon is stretched or torn, it is an ankle strain. When the big toe is sprained, it is known as turf toe. Achilles tendonitis is the overuse and inflammation of the Achilles tendon. Plantar fasciitis is the inflammation of the plantar fascia and generally occurs from overuse in athletics. Stress fractures are also caused from overuse and are small cracks in the bone.

Achilles tendon ruptures are common, but more serious. This injury occurs when the Achilles tendon, the largest tendon in the body, ruptures. In most cases, this causes severe pain and difficulty walking; some who have experienced this injury have reported, however, no signs or symptoms. A laceration is a deep cut that can occur anywhere on the body. Lacerations on the foot are rarer, but can occur from things like metal cleats landing on the foot.   

Treatment options cover a wide range of methods based upon the injury and its severity. Conditions like plantar fasciitis, stress fractures, Achilles tendonitis, turf toe and ankle sprains/ strains can heal on their own without immediate medical care, but seeing a podiatrist to monitor the injury is always recommended. Following the RICE (Rest, Icing, Compression, and Elevation) protocol is generally enough to treat minor injuries. This means resting the foot by either keeping pressure off the foot or not walking at all. Icing the injury will help reduce swelling and pain. Compressing the wound with a wrap will immobilize and help promote healing. Finally, keeping the wound elevated will also reduce swelling and also help the healing process.

It is important to note that even minor injuries can vary in severity, with grade one being a minor injury and grade three requiring urgent care by a podiatrist. Achilles tendon ruptures and lacerations on the foot generally require urgent medical care and treatment options that need a podiatrist. These could include imaging tests, stitches for cuts, rehabilitation, and casts or braces. Every case is different, however, so it is always recommended to see a podiatrist when pain in the foot does not disappear.
