Blisters are pockets of fluid that occur under the top layer of your skin. These fluid pockets are usually filled with pus, blood, or serum. Blisters may itch or hurt and can appear as a single bubble or in clusters.

The most common types of blisters are friction blisters. This type of blister may be caused by wearing shoes that are too tight. Friction blisters can also occur on the hands. A change in temperature may also cause blisters on the feet. In the freezing air, frostbite on your toes can lead to blisters, as well as sunburn from hot weather.

The best way to treat a blister is to keep it clean and dry. Most blisters will get better on their own. Once the skin absorbs the fluid within the blister, it will flatten and eventually peel off. You should avoid popping your blister unless you podiatrist does it for you. Additional treatment options include applying an ice pack to the blister or using over-the-counter blister bandages to cover the affected area.

If your blister becomes discolored, inflamed, or worsens it is advised that you speak to your podiatrist. Blisters that are yellow, green, or purple may be infected and require immediate medical attention. Blisters that are abnormally colored may be a sign of a more serious underlying health condition such as herpes.

Tarsal tunnel syndrome is a condition in which there is a compression of the posterior tibial nerve. The posterior tibial nerve runs along the inside of the ankle into the foot. Tarsal tunnel syndrome is named for the tarsal tunnel, which is a thin space along the inside of the ankle beside the ankle bones. This space contains various nerves, arteries, and tendons, and includes the posterior tibial nerve. The tibial nerve is the peripheral nerve in the leg responsible for sensation and movement of the foot and calf muscles. In tarsal tunnel syndrome the tibial nerve is compressed, causing tingling or burning, numbness, and pain.

Common causes of tarsal tunnel syndrome involve pressure or an injury. Injuries that produce inflammation and swelling in or around the tunnel may place pressure on the posterior tibial nerve. Direct pressure on the tibial nerve for an extended period of time, sometimes caused by other body structures close by or trauma to the tibial nerve, can result in tarsal tunnel syndrome. Diseases that damage nerves, such as diabetes or arthritis, may cause tarsal tunnel syndrome. Those with flat feet are at risk for developing the condition, as the extra pressure and strain placed on the foot may compress the posterior tibial nerve.

Feeling different sensations in the foot at different times is a common symptom of tarsal tunnel syndrome. An afflicted person may experience pain, tingling, burning or other unusual sensations in the foot of the affected leg. Symptoms are primarily felt on bottom of the foot and/or the inside of the ankle. Symptoms can appear suddenly and may occur due to overuse of the foot.

To diagnose tarsal tunnel syndrome, your podiatrist may examine the foot and tap the posterior tibial nerve to see if symptoms surface. He or she may also order an MRI to determine if a mass is present.

Treating tarsal tunnel syndrome will depend on the decision of your podiatrist. Multiple options are available, however, and can include rest, ice, immobilization, oral medications such as anti-inflammatory drugs (NSAIDS), physical therapy, injection therapy, orthotics, supportive shoes, braces, and surgery.

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.

The feet, being the foundation of the body, carry all of the body’s weight and are therefore prone to experiencing pain and discomfort. If you are experiencing foot pain, it is important to determine where in the foot you are experiencing this pain to help discover the cause of it. While pain can be experienced virtually anywhere in the foot, the most common sites of foot pain are in the heel and ankle.   

Heel pain can be due to a multitude of conditions including plantar fasciitis, Achilles tendinitis, and heel spurs. Pain experienced in the ankle can be a sign of an ankle sprain, arthritis, gout, ankle instability, ankle fracture, or nerve compression. In more serious cases, pain in the foot can be a sign of improper alignment or an infection.

Foot pain can be accompanied by symptoms including redness, swelling, stiffness and warmth in the affected area. Whether the pain can be described as sharp or dull depends on the foot condition behind it. It is important to visit your local podiatrist if your foot pain and its accompanying symptoms persist and do not improve over time.

Depending on the location and condition of your foot pain, your podiatrist may prescribe certain treatments. These treatments can include but are not limited to prescription or over-the-counter drugs and medications, certain therapies, cortisone injections, or surgery.

If you are experiencing persistent foot pain, it is important to consult with your foot and ankle doctor to determine the cause and location. He or she will then prescribe the best treatment for you. While milder cases of foot pain may respond well to rest and at-home treatments, more serious cases may take some time to fully recover.

Arthritis is an inflammation of the joints and it can occur at any joint in the body, especially in the foot. It generally effects those who are older, however, it can occur at any age. Although there are many different forms of arthritis, there are three main types that occur in the foot. The three types are osteoarthritis, rheumatoid arthritis, and gout.

The primary cause of osteoarthritis is aging. As you age, cartilage degenerates around the joints which causes friction and pain. Obesity can cause osteoarthritis through mechanical stress. Injuries that damage joints can increase the probability as well. Finally, a family history of osteoarthritis can also increase chances of having it.

Rheumatoid arthritis occurs when the immune system attacks the joint linings and weakens them over a long time. While there is no known cause of rheumatoid arthritis, obesity and smoking can increase your chances of getting it. Women are also more likely to get it than men.

Gout is a form of arthritis that occurs when there is too much uric acid in your blood and painful crystals form in your joints. Men are more likely to have gout than women. People who are obese or drink alcohol often are also more likely to develop gout. Furthermore, having diabetes, heart disease, high blood pressure, high cholesterol, gastric bypass surgery or a family history of gout may increase your likelihood of developing the condition.

Symptoms of arthritis include pain, stiffness, swelling in the joints. These symptoms can make it harder and more painful to walk. Physical activity can increase pain and discomfort. Furthermore, joint pain can worsen throughout the day for osteoarthritis. Gout attacks generally last several days with the first few being the worst.

Diagnosis of gout includes either a joint fluid test or a blood test. X-ray imaging can detect osteoarthritis but not gout. On the other hand, there is no blood test for osteoarthritis. Rheumatoid arthritis is difficult to diagnosis. Doctors utilize family and personal medical history, a physical examination, and antibody blood tests to determine if you have rheumatoid arthritis.

Treatment varies for the different kinds of arthritis. Anti-inflammatory medication or steroids can help reduce pain from inflammation of the joints. Changing shoe types can help with some symptoms. Wider shoes can help with discomfort from gout and osteoarthritis. High heels should be avoided. Shoes with proper arch support and that take pressure off the ball of the foot can help with rheumatoid arthritis. Drinking lots of water can also help rid uric acid from the blood. Losing weight, improving your diet, and limiting alcohol and smoking can also help prevent or lessen the symptoms of arthritis.

If you are having trouble walking or pain in your feet, see a podiatrist to check if you have arthritis.

Sesamoiditis is a condition that affects the joint that is just behind the big toe in the area known as the ball of the foot. It is most common in younger people and people who have just begun an exercise program. Since the sesamoid bones are like a pulley controlling the big toe, they can rub against each other and cause a gradual onset of pain. Pain may also be caused by the inflammation of tendons surrounding the bones. If ignored, sesamoiditis can lead to other, more serious problems such as severe irritation and fractures of the bones.

The cause of sesamoiditis is sudden increase in activity. The ball of your foot acts as a springboard to help you lift off when you are jogging or running. Sudden increase in the use of these bones or the tendon that controls them can cause irritation. The tendon then begins to develop inflammation and the joint begins to swell. People with smaller, bonier feet or those with a high arch are typically more susceptible to this condition.

Sesamoiditis is fairly simple to diagnose since the symptoms have a gradual onset rather than a sudden impact. The symptoms begin with slight irritation around the joint shortly after the increase in activity. The discomfort eventually turns to pain with light swelling and possibly redness. Although redness or bruising are rare, this may be a symptom. After each session of exercising, the aggravated joint becomes more irritated and increases into a very intense throbbing.

Treatment for sesamoiditis can vary depending on the severity of the situation. However, treatment is almost always approached in a noninvasive way. For a case that is just beginning the doctor may recommend a very strict rest period that will limit the activity allowed on the joint. If you must be active, a recommendation for as modified shoe or insole, along with bandaging and immobilizing the big toe will be made to ensure that pressure is not placed on the joint. For severe cases, it is typically recommended that the joint and the big toe be completely immobilized to allow adequate time to heal. Ice and an over the counter anti-inflammatory may can help with the pain and discomfort while you are at rest.

When you return to your regular exercise activities, it is recommended that you use an insole that will allow even distribution of impact to your entire foot, rather than just the balls of your foot. This will prevent further aggravation of the injury.
