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.

Plantar warts are growths that typically appear on the heels or other weight-bearing areas of the feet. These warts are caused by the human papillomavirus (HPV). The virus enters the body through breaks in the skin, such as cuts, that are on the bottom of the feet. Plantar warts are more likely to affect children and teenagers, people with weakened immune systems, people who have a history with plantar warts, and people who walk barefoot in environments exposed to a wart-causing virus.

If you suspect you have plantar warts, you may have the following symptoms: pain or tenderness while walking, a lesion that interrupts the ridges in the skin of your foot, small fleshy lesions on the bottom of the foot, or a callus where a wart has grown inward over a well-defined spot on the skin.

HPV causes plantar warts to form and is very common. There are more than 100 kinds of the virus in existence. However, only a few of them cause warts on the feet. The other types of HPV are likely to cause warts on other parts of the body.

If you have plantar warts, your podiatrist may try different treatment methods depending on your specific case. Some treatments for plantar warts are peeling medicines (salicylic acid), freezing medicines (cryotherapy), or surgical procedures. Laser treatments and vaccines are also used to treat plantar warts.

Blisters are a common ailment of people who wear shoes that are either too tight or rub against the feet in an uncomfortable way. Knowing the basics of blisters is important for understanding how they are formed and what treatments should be used for them.

A blister on the foot, or any other part of the body, is a small pocket that is filled with fluid. It usually forms on the upper layer of the skin because these layers are loose enough to allow a blister to form. The most common fluid in a blister is just a clear, watery-like fluid that usually isn’t cause for concern. However, blisters can fill up with blood if they are deep enough and pus if they have become infected with bacteria.

Blisters almost always form on the feet due to shoes rubbing up against the foot, where the friction causes blisters. These can occur after you have walked for a long period of time or when your shoes do not fit you properly. Your feet are also more prone to blisters if they are moist, so keeping them dry and clean is one preventative step you can take.

Preventing infection should be the number one concern when treating blisters, as well as relieving the pain they can cause. Using a bandage to cover up the blister will help it heal and prevent bacteria from entering it. New skin will form under the blister and eventually cause it to pop. You can also take a sterilized pin and try to pop it yourself.

If the blister is filled with pus or blood, seeking treatment from a doctor is ideal. Antibiotics may need to be taken in order to completely eliminate the bacteria inside the blister. See a doctor to have an antibiotic prescribed.

The best way to treat blisters is to prevent them all together. Keeping your feet dry and making sure that your shoes fit properly are just two of the steps you can take to prevent blisters. Shoes that are too tight or shoes that are too loose and allow your feet to slide in them will cause blisters. Applying a bandage to an area where you think a blister is about to form is another way you can prevent them.

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.  

Toenail fungus is a frustrating problem that affects many people. It can be persistent and hard to get rid of. As many different types of fungi are present throughout the environment, it is very easy to contract toenail fungus.  

The feet are especially susceptible to toenail fungus because shoes and socks create the ideal dark and moist environment that fungal infections thrive in. While fungal infections of the nail plate are quite common, if left untreated they can spread beyond the toenail and into the skin and other parts of the body.

Signs of toenail fungus include a thickened nail that has become yellow or brown in color, a foul smell, and debris beneath the nail. The toe may become painful due to the pressure of a thicker nail or the buildup of debris.

Treatment for toenail fungus is most effective during the early stages of an infection. If there is an accumulation of debris beneath the nail plate, an ingrown nail or a more serious infection can occur. While each treatment varies between patients, your podiatrist may prescribe you oral medications, topical liquids and creams, or laser therapy. To determine the best treatment process for you, be sure to visit your podiatrist at the first signs of toenail fungus.
