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.

Diabetes can cause two problems that can potentially affect the feet: Diabetic neuropathy and Peripheral Vascular Disease. Diabetic neuropathy occurs when nerves in your legs and feet become damaged, which prevents you from feeling heat, cold, or pain. The problem with diabetic neuropathy is that a cut or sore on the foot may go unnoticed and the cut may eventually become infected. This condition is also a main cause of foot ulcers. Additionally, Peripheral vascular disease also affects blood flow in the body. Poor blood flow will cause sores and cuts to take longer to heal. Infections that don’t heal do to poor blood flow can potentially cause ulcers or gangrene.

There are certain foot problems that are more commonly found in people with diabetes such as Athlete’s foot, calluses, corns, blisters, bunions, foot ulcers, ingrown toenails, and plantar warts. These conditions can lead to infection and serious complications such as amputation. Fortunately, proper foot care can help prevent these foot problems before they progress into more serious complications.       

Each day you should wash your feet in warm water with a mild soap. When you finish washing your feet, dry them carefully especially between your toes. You should also perform daily foot inspections to ensure you don’t have any redness, blisters, or calluses. Furthermore, if you are diabetic, you should always wear closed-toed shoes or slippers to protect your feet. Practicing these tips will help ensure that your feet are kept healthy and away from infection.

If you have diabetes, contact your podiatrist if you have any of the following symptoms on your feet: changes in skin color, corns or calluses, open sores that are slow to heal, unusual and persistent odor, or changes in skin temperature. Your podiatrist will do a thorough examination of your feet to help treat these problematic conditions.

The Achilles tendon is the strongest tendon in the human body. Its purpose is to connect the lower leg muscles and calf to the heel of the foot. This tendon is responsible for facilitating all types of movement, like walking and running. This tendon provides an enormous amount of mobility for the body. Any injuries inflicted to this tissue should be immediately brought up with a physician to prevent further damage. 

The most common injuries that can trouble the Achilles tendon are tendon ruptures and Achilles tendinitis. Achilles tendinitis is the milder of the two injuries. It can be recognized by the following symptoms: inflammation, dull-to-severe pain, increased blood flow to the tendon, thickening of the tendon, and slower movement time. Tendinitis can be treated via several methods and is often diagnosed by an MRI. 

An Achilles tendon rupture is trickier to heal, and is by far the most painful injury. It is caused by the tendon ripping or completely snapping. The results are immediate and absolutely devastating, and will render the patient immobile. If a rupture or tear occurs, operative and non-operative methods are available. Once the treatment begins, depending on the severity of the injury, recovery time for these types of issues can take up to a year. 

Simple preventative measures can be taken as a means to avoid both injuries. Prior to any movement, taking a few minutes to stretch out the tendon is a great way to stimulate the tissue. Calf raises, squats, leg curls, leg extensions, leg raises, lunges, and leg presses are all suggested ways to help strengthen the lower legs and promote Achilles tendon health. 

Many problems arise among athletes and people who overexert themselves while exercising. Problems can also happen among those who do not warm up properly before beginning an activity. Proper, comfortable shoes that fit correctly can also decrease tendon injuries. Some professionals also suggest that when exercising, you should make sure that the floor you are on is cushioned or has a mat. This will relieve pressure on the heels. A healthy diet will also increase tendon health. 

It is very important to seek out a podiatrist if you believe you have an injury in the Achilles region. Further damage could result in severe complications that would make being mobile difficult, if not impossible.

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.

Flatfoot is a condition that occurs when the arches on the foot are flattened, which allows the soles of the feet to touch the floor. Flatfoot is a common condition and it is usually painless.

Throughout childhood, most people begin to develop arches in their feet, however, some do not. Those who do not develop arches are left with flatfoot. The pain associated with flat feet is usually at its worse when engaging in activity. Another symptom that may occur with those who have this condition is swelling along the inside of the ankle.

It is also possible to have flexible flatfoot. Flexible flatfoot occurs when the arch is visible while sitting or standing on the tiptoes, but it disappears when standing. People who have flexible flatfoot are often children and most outgrow it without any problems.

There are some risk factors that may make you more likely to develop flatfoot. Those who have diabetes and rheumatoid arthritis have an increased risk of flatfoot development. Other factors include aging and obesity.

Diagnosis for flat feet is usually done by a series of tests by your podiatrist. Your podiatrist will typically try an x-ray, CT scan, ultrasound, or MRI on the feet. Treatment is usually not necessary for flat foot unless it causes pain. However, therapy is often used for those who experience pain in their flat feet. Some other suggested treatment options are arch supports, stretching exercises, and supportive shoes.
