Each foot, on average, has about 250,000 eccrine sweat glands that produce half a pint of sweat each day. Sweating is a natural and important bodily function. It regulates the body’s temperature by cooling the skin so that it does not overheat.  In individuals with hyperhidrosis, the sympathetic nervous system works in "overdrive", producing far more sweat than what is required. People with plantar hyperhidrosis experience an excess amount of sweat on their feet. It is estimated that 2% to 3% of all Americans suffer from some form of hyperhidrosis. This condition is often caused by neurologic, endocrine, infectious, and other systemic disease. Other factors that may trigger the condition are heat and emotions.

People with hyperhidrosis may notice an overabundance of sweat on their feet, along with a strong odor. The feet may also have a wet appearance coupled with infections such as athlete’s foot or toenail fungus. The sweat may even appear in low temperatures, such as during the winter months. People with plantar hyperhidrosis often need to change their socks several times throughout the day.

The specific cause of hyperhidrosis is unknown, and many believe it may be caused by over-activity. However, others believe the condition is genetic.  Caffeine and nicotine are known to cause excitement and nervousness which are two emotions that may make the condition worse.

If you are looking to treat your hyperhidrosis the most important thing you should do is wash your feet every day.  You may even need to wash your feet twice a day, if necessary.  You should also make sure you are wearing the right socks. Wool and cotton socks are both known to be good for ventilation, meaning they allow the feet to breathe. You should avoid socks made from nylon which trap moisture and lead to sogginess. Other common treatment options are over-the-counter antiperspirants that contain a low dose of metal salt.  In some cases, prescription strength antiperspirants that contain aluminum chloride hexahydrate may be necessary. In severe cases, surgery may be required.

Untreated hyperhidrosis can easily lead to complications.  Some complications that may arise from the disorder include nail infections, warts, and bacterial infections.  Consequently, it is important that you seek treatment from your podiatrist if you suspect that you may have plantar hyperhidrosis.

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.

Flatfoot is classified as having the entire sole of the foot in contact or near contact to the ground while standing. The disorder is also known as fallen arches, because those affected have no arch in their feet. Flexible flatfoot and rigid flatfoot are the two types of flatfoot.

A person has flexible flatfoot if when sitting or standing on their toes, they have an arch that disappears when they stand with the entire foot on the ground. Flexible flatfoot may also be called “pediatric flatfoot” because the condition first appears in childhood. It is common among infants because the arch does not develop until the age of 5 or 6 years. Rigid flatfoot is not as common in children as it is with adults. This type of flatfoot is developed due to the weakening of tibialis posterior muscle tendon, a major supporting structure of the foot arch. Development of this deformity is progressive and shows early signs of pain and swelling that begins at the inside arch of the foot and moves to the outside of the foot below the ankle. More severe cases can possibly lead to arthritis of the foot and ankle joints.

Although most cases of flatfoot involve people born with the condition, some less common causes are obesity, diabetes, pregnancy, and osteoporosis. In some cases, flatfoot may come with no symptoms at all and does not require any type of treatment. With other cases though, symptoms may include pain in the shin, knee, hips and lower back. If a person with flatfeet experiences such symptoms, a health care provider may suggest using orthotic devices or arch supports, which may reduce the pain. Wearing supportive shoes can also prove more comfortable with flatfeet and staying away from shoes with little support such as sandals. Other methods to relieve pain also include stretching the Achilles tendon properly and using proper form when doing any physical activity. In addition, losing weight can reduce the stress on your feet and reduce the pain.

People are constantly wearing improperly-fitting shoes. Though it isn’t hard, picking the right shoes does require keeping a few things in mind.

Shoe stores have rulers so you can get an exact measurement of your feet. Be sure to always measure your feet with your shoes on. Measuring just your foot will give you a shoe size that is 1-2 inches too small for picking the right size shoe.

To ensure that your toes won’t be cramped, make sure there is wiggle room. Approximately one inch should be between your toes and the tip of your shoe. It is easy to tell if your shoes are too tight, because you will start to experience pain, blisters, and swelling.

Additionally, do not always assume your shoe size will be the same at every store. Manufacturers sometimes run differently, and your size will vary from brand to brand. Make sure the stores you purchase from have return policies, in case there is a problem.

Rather than shoe shopping in the morning, it is advised to shop for shoes later in the day. Your feet will swell as the day passes. If shoes are purchased in the morning, they may not be as snug as they should be. Furthermore, not all two feet are the same size. Therefore, accommodations may be necessary.

An overall concern in buying shoes is making sure they are comfortable and supportive. There is no such thing as a shoe being ‘broken in’. If they are uncomfortable at the store, they likely will always be uncomfortable.

Since we do a lot of walking, it is important that we pick the right shoes. Our feet will benefit from this, and we will be happier and healthier because of it.

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.
