Podiatry is a branch of medicine that deals with the study, diagnosis, and treatment of foot and ankle conditions. There are various subdivisions in podiatry; biomechanics is one of them. Biomechanics is the way in which the bones, muscles, and joints of the feet and lower limb interact with each other.

Our feet play crucial roles in the way we move, and it is rare to have feet that are completely symmetrical. Common biomechanical issues include high or low arches or uneven leg heights. Excessive pronation often leads to fallen arches, or flat feet, and is a common cause of running injuries. People whose feet are over-pronated tend to have flexible and unstable feet. Pain is usually experienced during walking and running.

At times, people may be able to adapt to these abnormalities without any difficulties, but in other cases, these issues can cause a great deal of pain. This pain occurs because the joints, muscles, ligaments, and tendons are put under an excess amount of stress during movement. Common symptoms of biomechanical problems stemming from the feet include hip pain, knee pain, leg cramps, ankle pain, lower back pain, weak ankles, tripping, heel pain, Achilles pain, and shin splints.

Many biomechanical issues can be treated with orthotics. Orthotics are shoe insoles that are used to help control the way the foot operates.  They can provide relief from foot pain, heel pain, and knee pain. Depending on your specific case, you may need to purchase over-the-counter orthotics or custom orthotics to fit your feet. Your podiatrist will be able to prescribe the perfect orthotic for your feet to help you walk around with ease.

Gait is defined as the way we move our bodies from one point to another. This is usually done by either walking or running. Gait analysis is a method used to assess the way we walk or run to highlight biomechanical abnormalities. Gait analyses are a great way to take a detailed look at how you walk and how your foot moves while you walk. An examination of the feet will help your podiatrist understand why you are suffering pain in other parts of your body.

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.

The purpose of the body’s circulation system is to transport blood, oxygen, and nutrients throughout the body. A reduction of blood to a specific part of the body may cause one to experience symptoms of poor circulation. The most common causes of poor circulation in the feet are obesity, diabetes, and heart conditions such as peripheral artery disease (PAD). Common symptoms of poor circulation include tingling, numbness, throbbing, pain and muscle cramps.

Peripheral artery disease is a common cause of poor circulation in the legs. Symptoms of PAD are cramping, pain or tiredness in the leg or hip muscles while walking or climbing stairs. This pain tends to go away with rest and starts back up when you begin to walk.  It is a condition that causes the blood vessels and arteries to become narrow. Although PAD is more common in adults over the age of 50, it may also occur in younger people.  A similar condition called atherosclerosis causes arteries to stiffen up due to a buildup of plaque in the arteries and blood vessels.

Blood clots are also a common cause of poor circulation in the feet. Clots may obstruct blood vessels and if they occur in the legs, they may eventually lead to pain and discoloration. This occurrence is commonly known as deep vein thrombosis (DVT) and it may travel to the lungs. Varicose veins are another condition that may lead to poor circulation, and it is caused by incompetence of the valves in the veins. Women who are overweight are prone to developing this condition. Lastly, diabetes, which is correlated with poor blood sugar metabolism may lead to chronic poor circulation. Those with diabetes often suffer from cramping in the legs, calves, thighs and buttocks.

If you are looking for ways to avoid poor circulation there are some tips you can follow. One tip is to avoid sitting for too long. If you plan to sit down for a long period of time, you should try standing up occasionally, to improve your circulation. Another great way to avoid poor circulation is to exercise. Exercise is an excellent way to pump the heart and increase blood flow. Those who suffer from poor circulation should also avoid smoking, reduce their salt intake, and try to lose weight.

If you are experiencing symptoms from poor circulation in your feet, you should consult with your podiatrist to determine the best method for treatment for you. He or she may prescribe medication in addition to recommending specific lifestyle changes to improve your circulation.

Pain experienced in the ankle can be caused by a multitude of conditions. While the most common cause is an ankle sprain, other possible problems can include arthritis, gout, ankle instability, an ankle fracture, nerve compression, or tendinitis. In more serious cases, ankle pain can be a sign of improper alignment of the foot or an infection.

Ankle pain can often be accompanied by symptoms such as redness, swelling, stiffness, and warmth in the affected area. Pain can be described differently depending on the condition: short, stabbing pain and a dull ache are some examples. If such symptoms are persistent and do not improve after time, be sure to schedule an appointment with your local podiatrist.

Depending on the condition causing your ankle pain, different treatments may be prescribed by your podiatrist. For ankle sprains, the first step in treatment involves rest, ice, elevation, and compression. Be sure to avoid placing pressure on the ankle, use an ice pack several times a day, and use a compression bandage and elevation to reduce swelling. Other, more serious conditions may require the assistance of certain drugs and medications such as nonsteroidal anti-inflammatory drugs (NSAIDs), physical therapy, or even cortisone injections. 

Depending on the severity of your ankle pain and the condition behind it, recovery from ankle pain may take some time.

Consult with your foot and ankle doctor to best determine the cause of your ankle pain and the appropriate treatment.
