According to the American Diabetes Association (ADA), diabetes is a condition that affects approximately 23.6 million Americans.  Around 750,000 new cases are diagnosed each year, and the disease’s most common form, Type 2 diabetes, makes up for 90 to 95 percent of these cases.  Type 2 diabetes is especially prevalent among older Americans, those who are obese, and those who lead sedentary lifestyles.

Complications of the disease may lead to several foot and ankle-related conditions.  The loss of nerve sensation, or neuropathy, can cause diabetics to lose feeling at the bottom of the feet and therefore leave them unaware of pain, pressure, and heat.  Decreased circulation is another complication of diabetes that can slow down the healing of wounds and injuries; this can lead to the development of foot ulcers.

To prevent foot ulcers from forming, diabetics should examine their feet every day for small cuts and wear shoes that curtail pressure.  Constant monitoring for the risk factors associated with ulcer formation can allow for early detection and therefore lessen the possibility of ulcers or, even worse, amputation.  The removal of calluses and ingrown toenails should be left to the podiatrist to avoid improper removal and possible infection.

Diabetic patients may also experience foot deformities due to complications in their feet, such as limited joint mobility, muscle atrophy, and decreased fat padding.  These complications can increase pressure in certain areas of the foot, which in turn can cause certain deformities, such as hammertoe, to form.  Another deformity, Charcot foot, develops due to the collapsing of microfractures in the bones of the feet.  The resulting deformity is a foot that is flattened and wider in appearance.

To help minimize pressure and prevent the development of these diabetes-related foot and ankle conditions, your podiatrist may consider using orthotics or special shoes.  Charcot foot may be treated using walkers, custom orthotic insoles, or non-weight-bearing or rigid weight-bearing casts or braces.  In more serious cases, surgery may be considered to treat more developed deformities.  Ulcers can be further cared for with the help of proper diet, medication to control glucose, intensive wound care, and infection treatment.

The ankle joint is the point at which the bones of the leg and foot join. This joint is crucial because it is responsible for the foot’s mobility. Ankle pain is typically the result of inflammation from an injury to bones, joint space, cartilage, ligaments, tendons, or muscles in the area. Commonly associated symptoms with ankle pain are bruising, redness, numbness, stiffness, weakness, and tingling.

The most common causes of ankle pain are sprains and injuries. Ankle sprains are one of the most common musculoskeletal injuries. Sprains occur when the ligaments of the ankle become partially or completely torn due to sudden stretching. Sprains can occur on either the inner or outer sides of the ankle joint. Usually, these injuries occur when the ankle is twisted in an activity by stepping off an uneven surface. More specific causes include rheumatoid arthritis, gout, osteoarthritis, and Achilles tendonitis.

If you are experiencing ankle pain, you should consult with your podiatrist to choose the best method of care. Your doctor will conduct an examination of your ankle to determine the underlying cause of the pain.

Blisters are small pockets of fluid that occur on the top layers of the skin for several reasons. Friction, burns, and diseases are all known causes of blisters.  Smaller blisters are known as vesicles, while larger blisters are referred to as bulla. The fluid inside the bubble can be blood, pus, or serum; which is a clear liquid that protects the skin. In most cases, blisters are not a major health issue, but they can be an indicator of a more serious condition.  

Causes of blisters vary. Blisters are commonly caused by wearing poorly fitted shoes that rub against the foot. However, there are many other causes besides from friction; including burns, sunburn, insect bites, frostbite, poison ivy/oak, chemical exposure, impetigo, eczema, viral infections, and more.

Most blisters heal by themselves and do not require immediate medical care. If you have a blister, do not pop it since this may cause infection; it is advised to put a bandage over the blister to protect it. If the blister is large, causes pain, or if you have a fever, it is recommended that you see a doctor who can provide proper care. Blisters are easy to diagnose, and if considered prudent by the doctor, can easily be drained of fluid with a sterile needle as well.

To prevent blisters on the feet, wear shoes that fit properly and don’t cause rubbing. Socks can help prevent friction and it is recommended that you wear them if you are wearing shoes. Hand blisters can be avoided by wearing gloves during activities that cause friction against the hand. If you have a blister that pops, do not remove the dead skin, wash the area, apply antibiotic ointment, and cover with a bandage. It is okay in most cases to not seek immediate medical care for a blister if it was just caused by friction. However, if the blister causes pain or does not go away, it is suggested that you see a doctor for a diagnosis.

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.
