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.

While proper foot care is important for everybody, senior citizens have the tendency to be more susceptible to certain foot conditions. The elderly should therefore be well informed about any problems that may arise and about what they can do to properly avoid or treat them.

Some of the most common foot problems seniors are susceptible to include foot ulcers, ingrown toenails, fallen arches, and fungal nails. A foot ulcer is an open sore on the foot and can be a result of diabetes and decreased sensation in the feet. An ingrown toenail is defined as when the nail grows into the side of the toe. Fallen arches are indicated by the instep of the foot collapsing. A fungal nails is a condition that results in deformed and discolored toenails.

In order to avoid these conditions it is recommended that the feet be inspected by the patient on a regular basis. If these inspections are carried out routinely, there is a good likelihood that problems can be identified before they become severe, or can even be avoided altogether. If any abnormality is discovered, it is important that the individual consult a podiatrist for diagnosis and information on treatment options.

Proper foot hygiene is also important. Making sure that you always have clean, dry socks on can be a major deterrent to many different problems including bacterial infections, foot odor, and certain types of fungus. Wet feet are a major cause of many of these problems.  If your socks get wet, it is important to change them. Walking around in wet socks may not only lead to various infections, but can irritate the skin and result in a number of various complications. Clean, dry feet are less likely to be affected by fungal and other infections.

As people age, the fat present on your feet begins to deteriorate. The protective nature of this fat keeps the feet healthy by providing a barrier between your bones and the ground. This also aids in giving the skin on the feet a certain amount of elasticity. This is one factor that causes elderly people to develop some serious foot issues. Foot moisturizers can be helpful to avoid certain problems associated with this. However, water-based moisturizers do not work as well for elderly people as they do for the young. Instead, it is more effective to use an emollient instead. An emollient is effective because it binds the water in the foot, keeping it from becoming absorbed too readily which will result in dry skin. Emollients also have a special property called occlusion, which provides a layer of oil on the skin. This layer prevents the foot from drying up and can be very effective in treating dry skin disorders.  If you can keep the skin on your feet healthy, this will substantially reduce the number of foot problems you will encounter in old age.

Proper footwear is another way to keep feet healthy. Shoes that fit well and provide proper support help prevent ingrown toenails and fallen arches.

Certain medical conditions such as diabetes or poor blood circulation increase the risk for foot issues. For individuals with any of these conditions it is extremely important to conduct regular foot inspections to make sure that there are no sores or infections present.

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.

Podiatry is a branch of medicine that deals with the study, diagnosis, and treatment of foot and ankle conditions. There are various subdivisions in podiatry; biomechanics is one of them. Biomechanics is the way in which the bones, muscles, and joints of the feet and lower limb interact with each other.

Our feet play crucial roles in the way we move, and it is rare to have feet that are completely symmetrical. Common biomechanical issues include high or low arches or uneven leg heights. Excessive pronation often leads to fallen arches, or flat feet, and is a common cause of running injuries. People whose feet are over-pronated tend to have flexible and unstable feet. Pain is usually experienced during walking and running.

At times, people may be able to adapt to these abnormalities without any difficulties, but in other cases, these issues can cause a great deal of pain. This pain occurs because the joints, muscles, ligaments, and tendons are put under an excess amount of stress during movement. Common symptoms of biomechanical problems stemming from the feet include hip pain, knee pain, leg cramps, ankle pain, lower back pain, weak ankles, tripping, heel pain, Achilles pain, and shin splints.

Many biomechanical issues can be treated with orthotics. Orthotics are shoe insoles that are used to help control the way the foot operates.  They can provide relief from foot pain, heel pain, and knee pain. Depending on your specific case, you may need to purchase over-the-counter orthotics or custom orthotics to fit your feet. Your podiatrist will be able to prescribe the perfect orthotic for your feet to help you walk around with ease.

Gait is defined as the way we move our bodies from one point to another. This is usually done by either walking or running. Gait analysis is a method used to assess the way we walk or run to highlight biomechanical abnormalities. Gait analyses are a great way to take a detailed look at how you walk and how your foot moves while you walk. An examination of the feet will help your podiatrist understand why you are suffering pain in other parts of your body.

Heel pain can be difficult to deal with, especially if you do not know what the underlying cause is. If you ignore your heel pain, the pain can magnify and potentially develop into a chronic condition. Depending on the location of your heel pain, you have developed a specific condition.  

One condition is plantar fasciitis.  Plantar fasciitis is caused by the inflammation of the plantar fascia, or the band of tissue that connects the heel bone to the base of the toes. The pain from this condition is initially mild but can intensify as more steps are taken when you wake up in the morning. To treat this condition, medication will likely be necessary. Plantar fasciitis is often associated with heel spurs; both require rest and special stretching exercises.

There are various options your podiatrist may suggest for heel pain.  Treatment options for heel pain typically include non-steroidal anti-inflammatory drugs (NSAIDS), which may reduce swelling and pain. Other options are physical therapy, athletic taping, and orthotics. In severe cases of heel pain, surgery may be required.

Preventing heel pain is possible.  If you are looking to prevent heel pain from developing in the future, be sure to wear shoes that fit you properly and do not have worn down heels or soles. Be sure to warm up properly before participating in strenuous activities or sports that place a lot of a stress on the heels. If you are experiencing any form of heel pain, speak with your podiatrist to determine the underlying cause and receive the treatment you need.
