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.
Fungal infection of the toenail, or onychomycosis, typically appears as a gradual change in a toenail’s texture and color that involves brittleness and darkening. The fungal infection itself occurs beneath the surface of the nail. Aside from discoloration, other symptoms include the collection of debris beneath the nail plate, white marks on the nail plate, and a foul odor emanating from the nail. If ignored, the infection can spread into other nails and the skin; in severe cases, it can hinder one’s ability to work or walk.
The toenails are particularly vulnerable to contracting infection in moist environments where people are likely to be walking barefoot, such as around swimming pools, public showers, and locker rooms. Fungal infection may also be more likely to occur in nail beds that have been injured, and sufferers of chronic diseases such as diabetes, circulatory problems, or immunodeficiency conditions are particularly prone to developing fungal nails.
Fungal nails can be primarily prevented by practicing proper hygiene and regularly examining the feet and toes. Carefully washing the feet with soap and water and thoroughly drying the feet afterwards are essential. Other tips include wearing shower shoes in public areas, changing shoes and socks daily, keeping toenails clipped at a short length, wearing breathable shoes that fit properly, wearing moisture-wicking socks, and disinfecting home pedicure tools and instruments used to cut nails.
Fungal nail treatment may vary between patients and the severity of the condition. Your podiatrist may suggest a daily routine of cleansing that spans over a period of time to ease mild infections. Over-the-counter or prescription antifungal agents may also be prescribed, including topical and/or oral medications. Debridement, or the removal of diseased nail matter and debris, may also be performed. In more severe cases, surgical treatment may be needed. In some instances, the temporary removal of the fungal nail allows for the direct application of a topical antifungal to the nail bed. In other cases, a chronically painful fungal nail that has not responded to other treatments may be permanently removed; this allows the infection to be cured and avoids the growth of a deformed nail.
Diabetics must be wary of all wounds, regardless of depth or size. Diabetes, a chronic disease in which the body cannot properly use glucose the way it normally would, causes various complications that make wounds difficult to heal. Nerve damage or neuropathy will cause diabetics to have trouble feeling the pain of a blister or cut until the condition has significantly worsened or become infected. A diabetic’s weakened immune system can make even the most minor of wounds easily susceptible to infection. Diabetics are also more prone to developing narrow, clogged arteries, and are therefore more likely to develop wounds.
Wounds should be taken care of immediately after discovery, as even the smallest of wounds can become infected if enough bacteria build up within the wound. To remove dirt, wounds should be first rinsed under running water only. Soap, hydrogen peroxide, or iodine can irritate the injury and should be avoided. To prevent infection, apply antibiotic ointment to the wound and cover it with a bandage. The bandage should be changed daily. The skin around the wound may be cleaned with soap.
To prevent further exacerbation, see a doctor—especially if you have diabetes. Minor skin conditions can become larger problems if not properly inspected. As the wound heals, make sure to avoid applying pressure to the affected area.
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.
Toe pain can originate from corns, calluses, hammertoes, and bunions, as well as ingrown toenails, sprains, fractures, and dislocations. Corns develop as the toe rubs against the inside of a shoe which causes the skin to thicken as a form of protection. A corn is typically cone-shaped and has a small, hardened spot that points inward. When a corn is pressed into the skin, the toe becomes painful. Corns usually form on the top or side of the toe. A callus is also a thickened patch of skin that generally forms on the bottom of the foot. Calluses are the result of friction from the toe rubbing against the inside of a shoe. They may also occur by walking barefoot or having flat feet. A hammertoe is a bump on the knuckle of the second toe that is produced by wearing shoes that are too short for your feet. The bony protrusion rubs against the top of the shoe causing pain and irritation. A bunion is a malformation of the big toe. The base of the big toe pushes away from the smaller toes, forcing the top of the big toe to press toward the other toes. Bunions can be hereditary, or they can result from injury to the toe joint or from wearing high heels with a narrow toe box. The toe becomes inflamed, and a bump may develop at the end of the misplaced bone. Ingrown toenails typically affect the big toe and its surrounding skin. The nail will dig into the skin and become painful. Wearing tight or narrow shoes that compress the big toe causes the nail to grow into the fleshy part of the toe. Cutting toenails incorrectly can also add to the development of an ingrown toenail. A toe sprain originates from a torn or stretched ligament. Strapping the injured toe to the toe next to it for stabilization is common. A broken or fractured toe usually occurs from trauma like dropping a heavy object on it or bumping into something extremely hard and rigid. Osteoporosis, a thinning of the bones, can also bring about toe fractures.
Any of the conditions mentioned can lead to pain and irritation. While some are more serious than others, seeking an examination and diagnosis from a podiatrist is a good idea. A podiatrist can treat each ailment and get you back on your feet again without pain.
Neuropathy is the weakness, numbness, and pain in the hands and feet due to damage to the peripheral nerves. The peripheral nerves are responsible for sending information from the brain and spinal cord to the rest of your body. Causes of Neuropathy include: traumatic injuries, infections, metabolic problems, exposure to toxins, and diabetes.
Diabetes is the most common cause, with more than half of the diabetic population developing some type of neuropathy. There are several types of neuropathy and they vary based on the damage of the nerves. Mononeuropathy is classified as only one nerve being damaged. When multiple nerves are affected, it is referred as polyneuropathy. One of the types of polyneuropathy is distal symmetric polyneuropathy. It is the most common for people with diabetes and starts when the nerves furthest away from the central nervous begin to malfunction. The symptoms begin with pain and numbness in the feet and then they travel up to the legs. A rarer form of polyneuropathy is acute symmetrical peripheral neuropathy, which is a severe type that affects nerves throughout the body and is highly associated with Guillain-Barre syndrome, an autoimmune disorder that attacks the peripheral nervous system and can be fatal. Although there are many types of neuropathy, most of them share the same symptoms such as pain, extreme sensitivity to touch, lack of coordination, muscle weakness, dizziness, and digestive problems. Since neuropathy affects the nerves, those affected should be careful of burns, infection and falling, as depleted sensations disguise such ailments.
The best way to prevent neuropathy is to manage any medical conditions such as diabetes, alcoholism, or rheumatoid arthritis. Creating and managing a healthy lifestyle can also go a long way. Having a healthy diet full of fruits, vegetables, whole grains and lean protein can keep the nerves healthy. These types of food have the nutrients to prevent neuropathy. Regularly exercising can help as well, but it is best to consult with a doctor about the right amount. In addition to diet and exercise, avoiding risk factors will also prevent neuropathy. This includes repetitive motions, cramped positions, exposure to toxic chemicals, smoking and overindulging on alcohol.
In most cases, foot surgery is often chosen as the last available option for conditions that have otherwise been unsuccessfully treated. Surgery may be necessary for several reasons, including the removal of foot deformities (e.g. bone spurs or bunions), arthritis problems, reconstruction due to injury, and congenital malformations (e.g. club foot or flat feet). Regardless of one’s age, foot surgery may be the only successful option for treatment for certain conditions.
The type of surgery one undergoes depends on the type of foot condition the patient has. For the removal of a bunion growth, a bunionectomy is necessary. If the bones in the feet need to be realigned or fused together, a surgical fusion of the foot is needed. For pain or nerve issues, a patient may require surgery in which the tissues surrounding the painful nerve are removed. Initially, less invasive treatments are generally attempted; surgery is often the last measure taken if other treatments are unsuccessful.
While in many cases surgery is often deemed as the final resort, choosing surgery comes with certain benefits. The associated pain experienced in relation to the particular condition is often relieved with surgery, allowing patients to quickly resume daily activities. The greatest benefit, however, is that surgery generally eliminates the problem immediately.
Podiatry history has shown that foot treatments continue to evolve over time. In the field of foot surgery, endoscopic surgery is just one of the many advanced forms of surgery. As technology vastly improves so too will the various techniques in foot surgery, which already require smaller and smaller incisions with the use of better and more efficient tools. Thanks to such innovations, surgery is no longer as invasive as it was in the past, allowing for faster and easier recoveries.
Diabetes is the condition in which the body does not properly process food for use as energy. People with Type 1 diabetes cannot produce insulin, which is required for glucose to feed your body’s cells. It is typically caused by the immune system mistaking healthy cells for foreign invaders and destroying the insulin-producing cells in the pancreas. On the other hand, people with Type 2 diabetes cannot respond to insulin properly, and eventually cannot produce enough. The Centers for Disease Control and Prevention reports that over 30 million people in the United States have diabetes, with 1 in 4 having no idea they have it. Surprisingly, diabetes is the seventh leading cause of death in the US. The symptoms of diabetes include frequent urination, fatigue, hunger, and even blurry vision.
Diabetes can also affect the feet as well. Over time, diabetes can cause nerve damage to your feet, which could then lead to symptoms such as tingling, pain and numbness in the feet. Neuropathy can be very dangerous to a person with diabetes, since it prevents them from feeling injuries such as cuts or blisters in the feet, and if not detected early enough, may lead to infection. Neuropathy can also lead changes in the shape of your feet and toes. The best way for people with diabetes to prevent or delay neuropathy is keeping their blood glucose levels in their target range. This consists of eating right, having the correct amount of exercise, and taking medications.
Diabetes can also create calluses and foot ulcers as well. Calluses build up faster and occur more frequently with those affected by diabetes. If there are too many calluses, therapeutic shoes and inserts may be required. It is important to have calluses trimmed by a health professional, as doing it yourself may lead to infections. If these calluses continue to develop and thicken, they can lead to foot ulcers. Foot ulcers are open sores, that appear on the ball of the foot or on the bottom of the big toe. These ulcers can lead to future infections if not treated and may possibly result in losing a limb. It is important to report any ulcers to your podiatrist right away. Your doctor may take x-rays to examine the foot and clean out any dead and infected tissue.
Lastly, diabetes can also lead to poor circulation and peripheral arterial disease (PAD). The poor circulation in the feet and leg area is a result of diabetes narrowing and hardening, eventually slowing down the blood flow in that area. The best way to prevent this is to keep away from smoking and follow your doctor’s advice for maintaining blood pressure and cholesterol. PAD is similar to this complication. PAD is when blood vessels narrow or are blocked by fatty deposits. PAD also increases your risk of heart attacks and strokes and is a common condition to those affected by diabetes. The combination of both PAD and neuropathy may lead to infections and can result in amputation of certain limbs. PAD can be prevented with wearing the proper foot wear and regularly taking care of your feet.
If you want to take care of your feet, you should wash and dry them carefully and perform daily inspections to check for cuts, blisters, or swelling. Any physical activity you partake in should be approved by your health care provider. You should also be sure to wear special shoes if advised to do so by your doctor.
Our feet are arguably the most important parts of our bodies because they are responsible for getting us from place to place. However, we often don’t think about our feet until they begin to hurt. If you have pain in your feet, you need to first determine where on the foot you are experiencing it to get to the root of the problem. The most common areas to feel pain on the foot are the heel and the ankle.
Heel pain is most commonly attributed to a condition called plantar fasciitis. Plantar fasciitis occurs when the plantar fascia, which is the band of tough tissue connecting the heel bone to the toes becomes inflamed. Plantar fasciitis pain is usually worse in the morning, and it tends to go away throughout the day. If you have plantar fasciitis, you should rest your foot and do heel and foot muscles stretches. Wearing shoes with proper arch support and a cushioned sole has also been proven to be beneficial.
Some common symptoms of foot pain are redness, swelling, and stiffness. Foot pain can be dull or sharp depending on its underlying cause. Toe pain can also occur, and it is usually caused by gout, bunions, hammertoes, ingrown toenails, sprains, fractures, and corns.
If you have severe pain in your feet, you should immediately seek assistance from your podiatrist for treatment. Depending on the cause of your pain, your podiatrist may give you a variety of treatment options.
Toenail fungus is a frustrating problem that affects many people. It can be persistent and hard to get rid of. As many different types of fungi are present throughout the environment, it is very easy to contract toenail fungus.
The feet are especially susceptible to toenail fungus because shoes and socks create the ideal dark and moist environment that fungal infections thrive in. While fungal infections of the nail plate are quite common, if left untreated they can spread beyond the toenail and into the skin and other parts of the body.
Signs of toenail fungus include a thickened nail that has become yellow or brown in color, a foul smell, and debris beneath the nail. The toe may become painful due to the pressure of a thicker nail or the buildup of debris.
Treatment for toenail fungus is most effective during the early stages of an infection. If there is an accumulation of debris beneath the nail plate, an ingrown nail or a more serious infection can occur. While each treatment varies between patients, your podiatrist may prescribe you oral medications, topical liquids and creams, or laser therapy. To determine the best treatment process for you, be sure to visit your podiatrist at the first signs of toenail fungus.
