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 warts that are only found on the feet, hence the term “plantar”, which means “relating to the foot.” They are caused by the human papillomavirus, or HPV, and occur when this virus gets into open wounds on the feet. The warts themselves are hard bumps on the foot. They are easily recognizable, mostly found on the heels or ball of the foot. Plantar warts are non-malignant, but they can cause some pain, discomfort, and are often unsightly. Removing them is a common step toward treating them.

Plantar warts can cause some pain while standing, sometimes felt as tenderness on the sole of your foot. Unless the wart has grown into the foot behind a callus, you will be able to see the fleshy wart. A podiatrist should only be consulted if there is an excessive amount of pain. Plantar warts are not cancerous or dangerous, but they can affect your walking and continually reappear. Anyone who suffers from diabetes or a compromised immune system disease should seek out care immediately.

Podiatrists are easily able to diagnose plantar warts. They usually scrape off a tiny bit of the rough skin to make tiny blood clots visible and examine the inside of warts. However, a biopsy can be done if the doctor is not able to diagnose them from simply looking at them. Although plantar warts usually do not require an excessive amount of treatment, there are ways to go about removing them. A common method is to freeze them off using liquid nitrogen, removing them using an electrical tool, or burning them off via laser treatment. For a less invasive treatment option, topical creams can be used through a doctor’s prescription. This treatment method takes more time, however. Keep the wart covered for protection in between daily treatments.

The best way to avoid developing plantar warts is to avoid walking barefoot in public places. Avoid this especially if you have open sores or cuts on your feet. It is also important to avoid direct contact with warts in general, as they are highly contagious.

Diabetics must be wary of all wounds, regardless of depth or size. Diabetes, a chronic disease in which the body cannot properly use glucose the way it normally would, causes various complications that make wounds difficult to heal. Nerve damage or neuropathy will cause diabetics to have trouble feeling the pain of a blister or cut until the condition has significantly worsened or become infected. A diabetic’s weakened immune system can make even the most minor of wounds easily susceptible to infection. Diabetics are also more prone to developing narrow, clogged arteries, and are therefore more likely to develop wounds.

Wounds should be taken care of immediately after discovery, as even the smallest of wounds can become infected if enough bacteria build up within the wound.  To remove dirt, wounds should be first rinsed under running water only. Soap, hydrogen peroxide, or iodine can irritate the injury and should be avoided. To prevent infection, apply antibiotic ointment to the wound and cover it with a bandage. The bandage should be changed daily. The skin around the wound may be cleaned with soap.

To prevent further exacerbation, see a doctor—especially if you have diabetes. Minor skin conditions can become larger problems if not properly inspected. As the wound heals, make sure to avoid applying pressure to the affected area.

Foot and ankle pain can be a nuisance in a person’s life, especially if it happens frequently. The best way to prevent this type of pain, is to exercise often. Regular exercise of the foot includes stretching and strength exercises. Stretching exercises can help prevent injuries such as a sprained ankle, while strength exercises can prevent ailments such as plantar fasciitis.

Stretching exercises can help improve flexibility and the foot and ankle’s range of motion. These exercises can certainly help with those who participate in high-energy activities such as sports. Many athletes routinely perform foot and ankle exercises to prevent injuries like sprained ankles, which are common injuries where the tendons in the ankle are over stretched. Strength exercises help develop foot muscles for better support and protection.

Most exercises are simple and can be done at home, either standing or sitting. One chair exercise is called “limber up”. In this exercise, a person would start by sitting down with their feet flat on the floor. Then lift one leg up so the feet are not touching the floor, then rotate your foot clockwise 15-20 times, and 15-20 times counterclockwise. Repeat the same process with the opposite leg. Another sitting exercise helps stretch the back of your heel and requires an exercise band. It begins by looping the band around a heavy piece of furniture, or something stable that will not be moved when the band is tugged or pulled. Then sit directly in front of it, and slide one foot into the loop, so that the band curves around the forefoot. Start by pulling the forefoot back and holding it for 5-10 seconds. Doing this 10-15 times on each foot, will stretch the back of your heel, increasing your flexibility.

Foot exercises that require standing are also just as easy and simple. Referred as the “Achilles Stretch”, this exercise stretches the Achilles tendon, making it more flexible, helping prevent foot, ankle, and leg pain. It begins by first standing and facing the wall, with the arms outstretched and the palms on the wall. Then place one foot behind another keeping the back leg straight, and the forward leg bending at the knee. Make sure both heels are flat on the floor and adjust your stance accordingly. With your hips, lean forward to feel the stretch, you can also adjust the distance from your feet to feel the stretch in various parts of the calf. Make sure to hold the stretch for about 30 seconds and repeat the same process 3 times with each leg. An even easier foot exercise is simply walking on sand. Walking barefoot on sand both strengthens and stretches your feet.

Doing these exercises regularly can help prevent many foot and ankle problems. Other foot exercises can even relieve pain. For example, those affected with plantar fasciitis can simply sit down on a chair, and then place a tennis ball below their affected foot. By rolling the ball under the foot, and increasing or decreasing pressure, pain will be relieved. With any exercise, it is always important to do a small warmup such as walking a few laps around the house to get the blood flowing. If after doing an exercise to relieve pain such as the tennis ball exercise, or are unsure that your execution is correct, be sure to contact a podiatrist for further instruction.
