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.

There are several systemic diseases, or diseases that affect the whole body, that either display symptoms in the feet or affect the health of the feet. Common systemic diseases that affect the overall health of the feet, and the patient’s ability to walk comfortably, include gout, diabetes mellitus, neurological disorders, and arthritis, among others.

In gout, which is caused by an excessive buildup of uric acid in the body, the most common symptoms of pain, inflammation, and redness occur at the metatarsal/phalangeal joint at the base of the big toe. Any excess levels of uric acid crystallize and are deposited in tendons, joints, and surrounding bone and muscle tissue. Gout is commonly treated with NSAIDs to relieve pain and inflammation and other drugs to lower uric acid levels in the body. Gout most commonly affects those who are overweight, have low protein diets and lead a more sedentary lifestyle.

Diabetes mellitus is an increase in the level of blood sugar in which the body cannot counteract with naturally occurring insulin in the body. The three types of diabetes, Type I, Type II and Gestational Diabetes, are all signs the body is either not producing enough insulin or is not efficiently using the insulin that is produced. Gestational diabetes only affects women who are pregnant and have never, prior to pregnancy, exhibited symptoms of the disease.

There are two main issues that affect the feet that are commonly caused by diabetes. They include diabetic neuropathy and peripheral vascular disease. Diabetic neuropathy can lead to damaged nerves and affect the feet through numbness and loss of sensation. Peripheral vascular disease restricts the flow of blood to the foot and can, in extreme cases, lead to the necessity of amputating the foot. Peripheral issues that are caused by diabetes and can affect the foot include athlete’s foot, nail infections, corns, blisters, bunions, severe dry skin, plantar warts and ingrown toenails. These can all be attributed to the decrease of blood flow to the foot.

Neurological disorders and rheumatoid arthritis can also have severe impact on the health of the feet. Neurological disorders can affect the nerves in the main structure of the foot and cause loss of sensation and possible decreased muscle response. Rheumatoid arthritis can affect the bones and joint structures of the foot, making it impossible to walk normally without serious pain.

All systemic diseases that affect the foot can effectively be treated to minimize joint and muscle damage if they are diagnosed early and treated with medication and lifestyle therapy. Diabetes patients must monitor their blood sugar levels and work with their physician to keep their levels as close to normal as possible. Rheumatoid arthritis patients should work with their physician to ensure the proper medications are being taken to reduce the amount of damage to the joints of the body.

Have you ever gotten up from a chair or out of bed in the morning, and upon taking that first step, feel like your heel has stepped on a tack? Many people experience a feeling of sharp pain which radiates into their arch from their heel and which does not allow them to put their heel on the floor. Sometimes they need to sit back down, stand only on their toes and use the wall for balance. If you can take a few steps, it seems to go away and lessen, allowing you to then resume your activity. Later, throughout your day and after a period of rest, it can happen again. If this sounds familiar you may be suffering from your first attack of heel pain.

Heel pain is a debilitating condition that affects day to day activities. Running and walking both causes stress on the heel because the heel is the part of the foot that hits the ground first. This means that the heel is taking on your entire weight. Diagnosis and treatments for heel pain can be easily found through your podiatrist.

Plantar Fasciitis

One of the main causes of heel pain is a condition known as plantar fasciitis. The plantar fascia is a band of tissue that extends along the bottom of the foot, from the toe to the bottom of the heel. A rip or tear in this ligament can cause inflammation of these tissues, resulting in heel pain. People who do not wear proper fitting shoes are often at risk of developing problems such as plantar fasciitis. Unnecessary stress from ill-fitting shoes, weight change, excessive running, and wearing non-supportive shoes on hard surfaces are all causes of plantar fasciitis.

Achilles Tendonitis

Achilles tendonitis is another cause of heel pain. Similar to plantar fasciitis, inflammation of the Achilles tendon will cause heel pain due to stress fractures and muscle tearing. A lack of flexibility of the ankle and heel is an indicator of Achilles tendonitis. If left untreated, this condition can lead to plantar fasciitis and cause even more pain on your heel.

Heel Spur

A third cause of heel pain is a heel spur. A heel spur occurs when the tissues of the plantar fascia undergo a great deal of stress, leading to a separation of the ligament from the heel bone entirely. This results in a pointed fragment of bone on the ball of the foot, known as a heel spur.

Athlete’s foot, or tinea pedis, is a skin disease caused by a fungal infection.  The infection typically occurs between the toes, and the feet are most subject to this disease because shoes best create the warm, dark, and moist environment in which fungus thrives.  Other areas that create a similar environment, such as swimming pools, public showers, and locker rooms; can also promote fungi growth. 

Symptoms of athlete’s foot include dry skin, itching, scaling, inflammation, and blistering.  Sometimes, blisters can evolve into the cracks or breaks in the skin.  The exposed tissue can then create pain, swelling, and discharge.  The spread of infection can cause itching and burning as well.

While athlete’s foot commonly occurs between the toes, it may also spread to the toenails or soles of the feet.  Other parts of the body, such as the groin or underarms, can also become infected if they are touched after the original area of infection is scratched.  Aside from physical contact, athlete’s foot can also spread through the contamination of footwear, clothing or bedsheets.

Proper foot hygiene is essential in preventing athlete’s foot.  You can prevent the fungus from spreading by frequently washing your feet using soap and water, thoroughly drying the feet between the toes, changing shoes and socks every day to reduce moisture, and ensuring that bathroom and shower floors are disinfected.  Other tips include using shower shoes, avoiding walking barefoot in public environments, wearing light and airy shoes, and wearing socks that keep the feet dry.

While treatment for athlete’s foot can involve topical or oral antifungal drugs, mild cases of the infection can be treated by dusting foot powder in shoes and socks.  Any treatment used can be supplemented by frequently bathing the feet and drying the toes.  If proper foot hygiene and self-care do not ease your case of athlete’s foot, contact your podiatrist.  He will determine if the underlying cause of your condition is truly a fungus.  If that is the case, a comprehensive treatment plan may be suggested with the inclusion of prescription antifungal medications.

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.
