Corns are thickened areas on the skin’s surface, to the point of being irritating and sometimes painful. Commonly found on the feet, corns are circular or cone-shaped. They develop where there are areas of pressure or friction, such as on the little toe when it rubs up against shoes, or on the ball of your foot.
Corns are often confused with a callus, but there is a difference between them. Corns can be raised bumps that are painful to the touch. They consist of a rough, thick area of skin that may be dry or waxy. Corns tend to be surrounded by skin that is inflamed, and are usually much smaller than calluses.
Removing the dead skin that has built up is the key in treating corns. Salicylic acid medication is most common in accomplishing this. The acid works by dissolving keratin, which is the protein that makes up the majority of corns. You can purchase salicylic acid over-the-counter in products such as wart removers. It comes in a variety of forms such as medicated pads, drops, or creams. However, people who are diabetic should not use salicylic acid, but should instead consult their doctor immediately.
According to the product directions, applying the medication directly onto the corn will treat it. The top layer of the corn will begin to turn white after use. When that occurs, the layers of skin can then be peeled away, making the corn smaller. Shaving off corns with razors or other pedicure equipment is never a good idea. This can lead to infection. If your corn gets infected, and is not treated immediately, a visit to the doctor will be necessary.
Another way to treat corns and help prevent their return is by using orthotic inserts, fitted by a podiatrist. Inserts fit right into your shoes and adjusts the way your foot fits into your shoes. This fixes the way you walk. This will lower your chances of getting corns, and eliminate current corns by reducing rubbing from friction.
Surgery is rarely used to treat corns, but does occur on occasion. Surgery actually deals with the underlying issue that causes corns. During surgery, the bone is shaved and any abnormalities are corrected, thus reducing the amount of friction that occurs during walking.
To prevent corns, the first step is reducing friction. Always wear shoes that fit well and don’t rub your feet. Pads can be purchased if you notice rubbing developing. These pads can be purchased over-the-counter, and can be simply placed on the irritated area. Wearing cushioned insoles in your shoes can always reduce the friction, and making sure to wear well-fitting shoes. This will ensure that your foot is not being squeezed awkwardly, and prevent corns from forming in the first place.
Stress fractures are small breaks in the bone that are caused by repetitive stress. They typically occur due to overuse, forcing the bones of the foot or ankle to continually absorb the full impact of each step taken. Stress fractures can also be caused by abnormal foot structure, osteoporosis, bone deformities, or wearing improper footwear during exercise.
Stress fractures are common for individuals whose daily activities cause high levels of impact on their feet and ankles. Those who run, play tennis or basketball, or practice gymnastics tend to experience these fractures more frequently. Anyone is susceptible to this problem, though. Individuals who are normally sedentary and suddenly begin an intense, high impact workout may sustain stress fractures. This is because their muscles are not yet strong enough to handle and cushion the intensity of their activity. Osteoporosis may also cause someone to get stress fractures, because the disease weakens an afflicted person's bones and makes it easier for them to break down.
Pain from stress fractures typically occurs in the general area of the fracture. Pain can also manifest as “pinpoint pain” or pain that is felt when the site of the injury is touched, and can be accompanied by swelling. It may occur during or after activity, and it may disappear while resting and return when standing or moving. Engaging in any kind of activity, high impact or otherwise, will aggravate the pain. If the intensity of the activity increases before the stress fracture has properly healed, it can cause a full fracture.
Treatment can vary depending on the individual and the degree of injury. The primary way to treat a stress fracture is to rest the hurt foot. Some fractures will heal quickly with only a little bit of rest, while others may require a long rest period and the use of crutches, immobilization, or physical therapy. Under certain circumstances, surgery may be required to install support pins around the fracture to assist in healing.
If you are undergoing a new exercise regimen in running or some other kind of high impact activity, set incremental goals on a weekly basis so you can build up muscle strength. Make sure to wear supportive shoes to better protect you feet.
If you begin to experience any symptoms of stress fractures, you should stop exercising and rest. If the symptoms persist, consult with your podiatrist. Remembering these tips can help you prevent stress fractures to your foot and ankle, and allow you to continue living normally.
Heel spurs are calcium deposits that cause bone protrusions on the heel bone. Heel spurs are usually associated with plantar fasciitis, which occurs when the plantar fasciitis in the foot becomes inflamed. Typically, heel spurs don’t cause any symptoms. However, they can produce chronic or intermittent heel pain. Those who have had the condition often describe the irritation as a stabbing pain.
There are risk factors that may make you more likely to develop heel spurs. People who have abnormal walking gaits, run and jog on hard surfaces, are obese, or wear poorly fitting shoes are more likely to develop heel spurs.
Fortunately, there are precautions you can take to avoid developing heel spurs. One of the best ways to do this is by wearing well-fitting shoes with shock-absorbent soles. Another preventative technique is to choose running shoes if you plan on running, and walking shoes if you plan on walking. Shoes are made for different activities and it is important to research a shoe before you purchase a pair.
The pain associated with heel spurs often decreases the more you walk. However, a recurrence of pain after an extended period of rest or walking is likely to occur with this condition. Those with severe heel spur pain may opt to go the surgical route for treatment. However, more than 90% of those with the condition get better without surgical treatment. If you have a heel spur and want to know if surgery is right for you, you should go to your podiatrist and he or she will be able to conduct a pre-surgical test or exam to determine if you are an optimal candidate for surgery.
Ankle sprains occur when ligaments that support the ankle stretch beyond their limits and tear. These types of injuries are very common and can occur in people of all ages. Sprains may range from mild to severe, depending on how much damage is done to the ligaments. If a sprain goes untreated, a more severe sprain may occur which can further damage the ankle. Repeated ankle sprains can lead to chronic ankle pain.
There are some risk factors that can increase your risk of suffering a sprained ankle. Those who participate in sports, walk on uneven surfaces, have a prior ankle injury, are in poor physical condition, or wear improper shoes are more likely to get a sprained ankle.
There are a few symptoms to look out for if you suspect you are suffering from a sprained ankle. Some common symptoms are swelling, bruising, tenderness, and instability of the ankle. In cases where the tearing of the ligaments is severe, there may be a “popping” sound when the strain occurs.
The RICE method is proven to be effective in treating ankle sprains. RICE stands for Rest, Ice, Compression, and Elevation. Rest is important for treatment, especially within the first 24 to 48 hours. You should also ice your sprained ankle for the first 48 hours for 20 minutes at a time. A small piece of cloth should be placed between the ice and the affected area. For the compression step, you should wear a brace that is snug, but not too tight that it cuts off circulation. When choosing a brace, be sure to choose one that is suitable for the type of ankle sprain you have. Lastly, you should elevate your foot above the heart as often as possible.
After you treat a sprain, you should go through rehabilitation to prevent the injury from occurring again. There are three phases to the rehab process. The first phase involves resting, protecting, and reducing the swelling of the injury. The second phase consists of restoring the ankle’s flexibility, range of motion, and strength. The third phase consists of slowly returning to activity and maintenance exercises.
If you suspect you have an ankle sprain, you shouldn’t hesitate to consult with your podiatrist. Your podiatrist will be able to give you a proper diagnosis and a suitable treatment option for your condition.
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 injuries are common among athletes and those who exercise frequently. Most of these injuries are non-life-threatening and can heal in weeks with proper treatment and care. Serious injuries, however, require urgent medical treatment.
Common minor injuries include ankle sprains, ankle strains, Achilles tendonitis, plantar fasciitis, stress fractures, and turf toe. An ankle sprain is when the ligaments in the ankle have either become stretched or torn. When the muscle or tendon is stretched or torn, it is an ankle strain. When the big toe is sprained, it is known as turf toe. Achilles tendonitis is the overuse and inflammation of the Achilles tendon. Plantar fasciitis is the inflammation of the plantar fascia and generally occurs from overuse in athletics. Stress fractures are also caused from overuse and are small cracks in the bone.
Achilles tendon ruptures are common, but more serious. This injury occurs when the Achilles tendon, the largest tendon in the body, ruptures. In most cases, this causes severe pain and difficulty walking; some who have experienced this injury have reported, however, no signs or symptoms. A laceration is a deep cut that can occur anywhere on the body. Lacerations on the foot are rarer, but can occur from things like metal cleats landing on the foot.
Treatment options cover a wide range of methods based upon the injury and its severity. Conditions like plantar fasciitis, stress fractures, Achilles tendonitis, turf toe and ankle sprains/ strains can heal on their own without immediate medical care, but seeing a podiatrist to monitor the injury is always recommended. Following the RICE (Rest, Icing, Compression, and Elevation) protocol is generally enough to treat minor injuries. This means resting the foot by either keeping pressure off the foot or not walking at all. Icing the injury will help reduce swelling and pain. Compressing the wound with a wrap will immobilize and help promote healing. Finally, keeping the wound elevated will also reduce swelling and also help the healing process.
It is important to note that even minor injuries can vary in severity, with grade one being a minor injury and grade three requiring urgent care by a podiatrist. Achilles tendon ruptures and lacerations on the foot generally require urgent medical care and treatment options that need a podiatrist. These could include imaging tests, stitches for cuts, rehabilitation, and casts or braces. Every case is different, however, so it is always recommended to see a podiatrist when pain in the foot does not disappear.
Tarsal tunnel syndrome is a condition in which the tibial nerve, located in the tarsal tunnel in the foot, is compressed. The tibial nerve can become compressed from injury, such as an ankle sprain, flat feet, and lesions. Arthritis, diabetes, and varicose veins can also cause swelling and thus result in nerve compression.
Symptoms of tarsal tunnel syndrome include several different sensations in the sole of the foot, inside the ankle, and around the tibial nerve. These sensations include shooting pains, numbness or reduced sensation, pins and needles, burning, and tingling. Symptoms tend to worsen with greater activity to the area. In rare and severe occasions, this can change the muscles in the foot.
If you suspect you have tarsal tunnel syndrome, you should consult with your podiatrist. He or she will examine your medical history to see if you have a history of diabetes, arthritis, or flat feet. They will also check to see if you have suffered an injury to the area recently. An electrical test will be conducted to check if the nerve has been damaged. A simpler Tinel’s Test might also be used. This includes simply tapping the nerve to create a sensation. An MRI scan of the area may also be used.
Treatments vary greatly for tarsal tunnel syndrome. Treatments include both nonsurgical and surgical options depending upon the severity of the condition. Nonsurgical options include anti-inflammatory medication and steroid injections to the area. Orthotics, such as a splint or brace that immobilizes the foot, is another noninvasive option. For those with flat feet, custom shoes can be made to offer better foot support. Surgical options include a tunnel tarsal release, in which an incision is made behind the ankle down to the arch of the foot. This releases the ligament and relieves pressure off the nerve. Some doctors use a more minimally invasive surgery, where smaller incisions are made in the ankle and the ligament is stretched out.
If you are suffering from painful sensations in your foot, see a podiatrist who can determine if you are experiencing tarsal tunnel syndrome. Tarsal tunnel syndrome that is left unchecked can cause permanent nerve damage to the foot.
Hammertoes are painful deformities that frequently form on the second, third, or fourth toe. The condition is often caused by an issue in foot mechanics. This can be caused by the person’s specific gait or the manner in which they walk, or by shoes that do not comfortably fit the deformity. Hammertoes can be formed after wearing shoes that are too narrow or short for the foot or have excessively high heels. Shoes that are not properly sized will force the toes into a bent position for long periods of time. This can cause the muscles to shorten and toes to bend into the deformity of a hammertoe.
Hammertoe can also be caused by complications from rheumatoid arthritis, osteoarthritis, trauma to the foot, heredity, or a cerebral vascular accident. Pain and difficult mobility of the toes, deformities, calluses, and corns are all symptoms of a hammertoe.
Someone who suspects they have the symptoms of a hammertoe should consult with a physician—particularly a podiatrist. Podiatrists diagnose and treat complications of the foot and ankle. If the podiatrist discovers that the affected toes are still flexible, treatment for the hammertoe may simply involve exercise, physical therapy, and better-fitting shoes. Treatment for hammertoes typically involves controlling foot mechanics, such as walking, through the use of customized orthotics.
For more serious cases in which the toes have become inflexible and rigid, surgery may be suggested. During the operation, the toe would receive an incision to relieve pressure on the tendons. A re-alignment of the tendons may then be performed by removing small pieces of bone to straighten the toe. In some cases, the insertion of pins is needed to keep the bones in the proper position as the toe heals. The patient is usually allowed to return home on the same day as the surgery.
If surgery is performed to repair a hammertoe, following the postoperative directions of your doctor is essential. Directions may include several stretches, picking up marbles with your toes, or attempting to crumple a towel placed flat against your feet. Wear shoes that have low heels and a wide amount of toe space to maintain comfort. Closed-toe shoes and high heels should be avoided. Shoes with laces allow the wearer to adjust how fitted he or she may want the shoes to be and also allow for greater comfort. To provide adequate space for your toes, select shoes that have a minimum of one-half inch of space between the tip of your longest toe and the inside of the shoe. This will also relieve pressure on your toes and prevent future hammertoes from forming.
Other preventative measures that can be taken include going shopping for new shoes in the middle of the day. Your feet are its smallest in the morning and swell as the day progresses. Trying on and purchasing new shoes midday will give you the most reliable size. Be sure to check that the shoes you purchase are both the same size. If possible, ask the store to stretch out the shoes at its painful points to allow for optimum comfort.
The Achilles tendon is the largest tendon in the body; it is a tough band of fibrous tissue that stretches from the bones of the heel to the calf muscles. This tendon is what allows us to stand on our toes while running, walking, or jumping, it is common for this tendon to become injured. In severe cases, the Achilles tendon may become partially torn or completely ruptured. However, this tendon is susceptible to injury because of its limited blood supply and the high level of tension it endures.
The people who are more likely to suffer from Achilles tendon injuries are athletes who partake in activities that require them to speed up, slow down, or pivot. Consequently, athletes who engage in running, gymnastics, dance, football, baseball, basketball, or tennis are more likely to suffer from Achilles tendon injuries. Additionally, there are other factors that may make you more prone to this injury. People who wear high heels, have flat feet, tight leg muscles or tendons, or take medicines called glucocorticoids are more likely to have Achilles tendon injuries.
A common symptom of an Achilles tendon injury is pain above the heel that is felt when you stand on your toes. However, if the tendon is ruptured, the pain will be severe, and the area may become swollen and stiff. Other symptoms may be reduced strength in the lower ankle or leg area, and reduced range of motion in the ankle. When the Achilles tendon tears, there is usually a popping sound that occurs along with it. People who have acute tears or ruptures may find walking and standing to be difficult.
If you suspect you have injured your Achilles tendon, you should see your podiatrist to have a physical examination. Your podiatrist will likely conduct a series of tests to diagnose your injury including a “calf-squeeze” test. Calf squeeze tests are performed by first squeezing the calf muscle on the healthy leg. This will pull on the tendon and consequently cause the foot to move. Afterward, the same test will be performed on the injured leg. If the tendon is torn, the foot won’t move because the calf muscle won’t be connected to the foot.
Although ankle sprains may not be as serious as a broken ankle, they should be given immediate attention and care. An ankle sprain can lead to a significant amount of pain, as well as limited mobility. They are often characterized by the swelling and discoloration of the skin. This occurs when the ligaments are stretched beyond their limits.
The simple act of walking can sometimes cause a sprain, which makes ankle sprains a very common injury that can happen to anyone. They occur when the ankle twists in an awkward way or rolls over itself, causing a pop or snap in the tendons around the ankle. Some people are more at risk than others. These include athletes who continually push their bodies to the limits and also people who have previously suffered accidents to the feet, ankles, or lower legs.
Most of the time, an ankle sprain is not severe enough for hospital attention. There are many at-home treatment options available, including propping the leg up above your head to reduce blood flow and inflammation, applying ice packs to the affected area as needed, taking over-the-counter pain relievers and anti-inflammatory medication, using an ACE bandage to wrap and support the injured ankle, and most importantly, remaining off your feet until the ankle has fully healed.
Despite this, an ankle sprain can turn into a severe injury that might require hospitalization. If the ankle ligaments or muscles are damaged from a tear or rip, that is one sign that the sprain is severe enough for hospital attention and possibly for surgery. Even after the surgery, the recovery process can be long. You may need to have rehabilitation sessions administered by your podiatrist to get your ankle back to full health.
The severity of your sprain might become apparent if you are unable to stand or walk, consistent pain occurs over a prolonged period of time, swelling is much more severe than initially present, or if you start to experience tingling or numbness. These signs may indicate that your ankle sprain might actually be a broken ankle, an injury that requires immediate medical attention.
Although they are not completely avoidable, ankle sprains can be curbed with some preventative treatment measures. These include wearing appropriate-fitting shoes that not only provide a comfortable fit, but also ankle support. It is also recommended to stretch before doing any kind of physical activity, as this will help lower your body’s chance for an injury.
