Sever's disease, also known as calcaneal apophysitis, is a medical condition that causes heel pain in children’s feet while they’re growing. Sever's disease occurs most commonly in boys and girls between the ages of 8 and 14.

Sever's disease occurs when the child’s growth plate, or the calcaneal epiphysis, an area attached to the Achilles tendon, is injured or when the muscles and tendons of the growing foot do not keep pace with bone growth. The result is constant pain experienced at the back of the heel and the inability to put any weight on the heel. This forces the child to bear weight on their toes while walking. When a toe gait develops, the child must change the way they walk to avoid placing weight on the painful heel. If this is not properly addressed, this can lead to further developmental problems.

The most common symptom of Sever's disease is acute pain felt in the heel when a child engages in physical activity such as walking, jumping or running. Children who are active athletes are among the group most susceptible to experiencing Sever's disease. This is due to the extreme stress and tension placed on their growing feet. The rolling movement of the foot during walking or running and obesity are both additional conditions linked to causing Sever's disease.

The first step in treating Sever's disease is to rest the foot and leg and avoid physical activity. Over the counter pain-relieving and anti-inflammatory medications can be helpful for reducing the amount of heel pain. A child with Sever's disease should also wear shoes that properly support the heel and the arch of the foot. Consider purchasing orthotic shoe inserts which can help support the heel and foot while it is healing. Most patients with Sever's disease symptoms report an eventual elimination of heel pain after wearing orthotic insoles that support the affected heel.

Sever's disease may affect either one heel or both. It is important for a child experiencing heel pain to be examined by a foot doctor who can apply the squeeze test. The squeeze test compresses both sides of the heel in order to determine if there is intense pain. Discourage any child diagnosed with Sever's disease from going barefoot as this can intensify the problem. Apply ice packs to the affected painful heel two or three times a day for pain relief.

Exercises that help stretch the calf muscles and hamstrings are effective at treating Sever's disease. An exercise known as foot curling has also proven to be very effective at treating Sever's disease. When foot curling, the foot is pointed away from the body, then curled toward the body to help stretch the muscles. The curling exercise should be done in sets of 10 or 20 repetitions and repeated several times throughout the day.

Treatment methods can continue for at least 2 weeks and as long as 2 months before the heel pain completely disappears. A child can continue doing daily stretching exercises for the legs and feet to prevent Sever’s disease from returning.

Peripheral artery disease (PAD), or peripheral arterial disease, is a circulatory problem in which there is a reduction of blood flow to the limbs due to narrowed arteries. When peripheral artery disease develops, the extremities do not receive enough blood flow; this may cause symptoms to develop such as claudication, or leg pain when walking. The legs are the most common site of peripheral artery disease.

Claudication, or leg pain when walking, is one of several symptoms that can develop due to peripheral artery disease. Other symptoms caused by the disease include painful cramping in the hips, thighs, or calves after certain activities; leg numbness or weakness; coldness in the lower leg or foot; sores on the lower extremities that do not heal; hair loss on the lower extremities; and a missing or weak pulse in the lower extremities. In more severe cases, pain may even occur when the body is at rest or when lying down.

Peripheral artery disease is typically caused by atherosclerosis, a condition in which fatty deposits build up in the arterial walls and reduce blood flow. Smoking, diabetes, obesity, high blood pressure, and high cholesterol are some of the risk factors for peripheral artery disease.

If you are experiencing pain, numbness, or other symptoms in the lower extremities, see your healthcare professional immediately. Diagnosed peripheral artery disease can be treated with various medications, angioplasty and surgery, exercise programs, or alternative medicine. It is important to consult a healthcare professional to determine the best treatment for you.

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.  

Neuropathy is a condition in which the nerves in the body become damaged from a number of different illnesses. Nerves from any part of the body, including the foot, can be damaged. There are several forms of neuropathy including peripheral neuropathy, cranial neuropathy, focal neuropathy, and autonomic neuropathy. Furthermore there is also mononeuropathy and polyneuropathy. Mononeuropathies affect one nerve while polyneuropathies affect several nerves. Causes of neuropathy include physical injury, diseases, cancers, infections, diabetes, toxic substances, and disorders. It is peripheral neuropathy that affects the feet.

The symptoms of neuropathy vary greatly and can be minor such as numbness, sensation loss, prickling, and tingling sensations. More painful symptoms include throbbing, burning, freezing, and sharp pains. The most severe symptoms can be muscle weakness/paralysis, problems with coordination, and falling.

Podiatrists rely upon a full medical history and a neurological examination to diagnose peripheral neuropathy in the foot. More tests that may be used include nerve function tests to test nerve damage, blood tests to detect diabetes or vitamin deficiencies. Imaging tests, such as CT or MRI scans, might be used to look for abnormalities, and finally nerve or skin biopsies could also be taken.

Treatment depends upon the causes of neuropathy. If the neuropathy was caused by vitamin deficiency, diabetes, infection, or toxic substances, addressing those conditions can lead to the nerve healing and sensation returning to the area. However if the nerve has died, then sensation may never come back to the area. Pain medication may be prescribed for less serious symptoms. Topical creams may also be tried to bring back sensation. Electrical nerve stimulation may be used for a period of time to stimulate nerves. Physical therapy can strengthen muscle and improve movement. Finally surgery might be necessary if pressure on the nerve is causing the neuropathy.

If you are experiencing sensation loss, numbness, tingling, or burning sensations in your feet, you may be experiencing neuropathy. Be sure to talk to a podiatrist to be diagnosed right away.
