Hyperhidrosis of the Feet
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.
Plantar Fasciitis
Plantar fasciitis is one of the most common causes of heel pain. The plantar fascia is the thick band of tissue that connects the heel bone to the toes. When this band of connective tissue becomes inflamed, plantar fasciitis occurs. Fortunately, this condition is treatable.
There are several factors that may put you at a greater risk for developing plantar fasciitis. One of the biggest factors is age; plantar fasciitis is common in those between the ages of 40 to 60. People who have jobs that require them to be on their feet are also likely to develop plantar fasciitis. This includes factory workers, teachers, and others who spend a large portion of their day walking around on hard surfaces. Another risk factor is obesity because excess weight can result in extra stress being placed on the plantar fascia.
People with plantar fasciitis often experience a stabbing pain in the heel area. This pain is usually at its worst in the morning, but can also be triggered by periods of standing or sitting. Plantar fasciitis may make it hard to run and walk. It may also make the foot feel stiff and sensitive, which consequently makes walking barefoot difficult.
Treatment for plantar fasciitis depends on the severity of the specific case of the condition. Ice massage applications may be used to reduce pain and inflammation. Physical therapy is often used to treat plantar fasciitis, and this may include stretching exercises. Another treatment option is anti-inflammatory medication, such as ibuprofen.
If you suspect that you have plantar fasciitis, meet with your podiatrist immediately. If left untreated, symptoms may lead to tearing and overstretching of the plantar fascia. The solution is early detection and treatment. Be sure to speak with your podiatrist if you are experiencing heel pain.
Getting the Right Shoe Size
If you want to ensure the long-term health of your feet, you should choose the right pair of shoes to wear on an everyday basis. Poorly fitting shoes will not only be uncomfortable, but they may also cause foot pain and unwanted foot conditions. When looking for a new pair of shoes, there are certain factors you should look for.
One of the most crucial tips you can follow is to always try shoes on in the afternoon. It is normal for feet to swell throughout the day, which means your shoe size may be different in the morning compared to what it is at night. To be safe, you should go with the slightly bigger size to ensure that your feet have enough room within your shoes.
Another rule is to never buy shoes that are too tight (Many people buy shoes that are too tight for their feet and expect the shoes to stretch out). If you are looking for a pair of running sneakers, you can go to a specialty running shoe store to have your feet properly sized. When you purchase shoes in-store, walk around in them to make sure the shoes you are going to buy fit you properly. Take some time to make sure the shoes are comfortable for your feet
The upper section of your shoe should be made from a softer, more flexible material. The material that makes up the shoe should not be slippery. Arch support should be a key factor in the decision-making process for shoes. Arch support is crucial because it will prevent the arches in your feet from collapsing. If your arches collapse, the plantar fascia may begin to stretch out which could lead to plantar fasciitis.
Many problematic foot conditions may be prevented by wearing properly fitting shoes. Some of these unwanted conditions are bunions, corns, calluses, pain, stress fractures, and plantar fasciitis. If you are suffering from any of these ailments you may want to speak with your podiatrist.
Tarsal Tunnel Syndrome
Tarsal tunnel syndrome is a condition in which there is a compression of the posterior tibial nerve. The posterior tibial nerve runs along the inside of the ankle into the foot. Tarsal tunnel syndrome is named for the tarsal tunnel, which is a thin space along the inside of the ankle beside the ankle bones. This space contains various nerves, arteries, and tendons, and includes the posterior tibial nerve. The tibial nerve is the peripheral nerve in the leg responsible for sensation and movement of the foot and calf muscles. In tarsal tunnel syndrome the tibial nerve is compressed, causing tingling or burning, numbness, and pain.
Common causes of tarsal tunnel syndrome involve pressure or an injury. Injuries that produce inflammation and swelling in or around the tunnel may place pressure on the posterior tibial nerve. Direct pressure on the tibial nerve for an extended period of time, sometimes caused by other body structures close by or trauma to the tibial nerve, can result in tarsal tunnel syndrome. Diseases that damage nerves, such as diabetes or arthritis, may cause tarsal tunnel syndrome. Those with flat feet are at risk for developing the condition, as the extra pressure and strain placed on the foot may compress the posterior tibial nerve.
Feeling different sensations in the foot at different times is a common symptom of tarsal tunnel syndrome. An afflicted person may experience pain, tingling, burning or other unusual sensations in the foot of the affected leg. Symptoms are primarily felt on bottom of the foot and/or the inside of the ankle. Symptoms can appear suddenly and may occur due to overuse of the foot.
To diagnose tarsal tunnel syndrome, your podiatrist may examine the foot and tap the posterior tibial nerve to see if symptoms surface. He or she may also order an MRI to determine if a mass is present.
Treating tarsal tunnel syndrome will depend on the decision of your podiatrist. Multiple options are available, however, and can include rest, ice, immobilization, oral medications such as anti-inflammatory drugs (NSAIDS), physical therapy, injection therapy, orthotics, supportive shoes, braces, and surgery.
