Hyperhidrosis of the feet, also termed plantar hyperhidrosis, is characterized by excessive sweating of the feet that can be onset by any cause, such as exercise, fever, or anxiety. Most people suffering from hyperhidrosis of the feet also experience hyperhidrosis of the hands, or palmar hyperhidrosis. Approximately 1-2% of Americans suffer from this disorder.
Sweating is a healthy process utilized by the body in order to cool itself and maintain a proper internal temperature, which is controlled by the sympathetic nervous system. In individuals with hyperhidrosis, the sympathetic nervous system works in "overdrive", producing far more sweat than is actually needed.
Plantar hyperhidrosis is considered primary hyperhidrosis. Secondary hyperhidrosis refers to excessive sweating that occurs in an area other than the feet, hands, or armpits, and this indicates that is related to another medical condition, such as menopause, hyperthyroidism, or Parkinson's disease.
Symptoms of hyperhidrosis of the feet can include foot odor, athlete's foot, infections, and blisters. Because of the continual moisture, shoes and socks can rot which creates an additional foul odor and can ruin the material, requiring shoes and socks to be replaced frequently. In addition to the physical symptoms, emotional health is often affected as this disorder can be very embarrassing.
If left untreated, hyperhidrosis will usually persist throughout an individual's life. However, there are several treatment options available. A common first approach to treating hyperhidrosis of the feet is a topical ointment. Aluminum chloride, an ingredient found in antiperspirants, can be effective at treating hyperhidrosis if used in high concentration and applied to the foot daily. Some individuals can experience relief this way, while others encounter extreme irritation and are unable to use the product. Another procedure is the use of Botulinum Toxin A, commonly referred to as Botox. This is injected directly into the foot, and is effective at minimizing the sweat glands in the injected area. These injections must be repeated every 4 to 9 months.
If these treatments are ineffective, oral prescription medications may be taken in an effort to alleviate the symptoms. Again, some will experience relief while others do not. Going barefoot reportedly provides relief for most sufferers.
A final approach to combating hyperhidrosis of the feet is through surgery. Surgery has been less successful on patients with plantar hyperhidrosis than on those with palmar hyperhidrosis. It is only recommended when sweating is severe and other treatments have failed to work. This kind of surgery usually involves going into the central nervous system, and cutting nerves to stop the transmission of signals telling the foot to sweat.
While not a serious issue, toenail fungus, or onychomycosis, can be an embarrassing and uncomfortable condition to experience. Toenail fungus is often caused from public areas that harbor fungi and improper cleaning/drying of the foot. Once infected, the fungus grows deeper into the nail and can be very hard to get rid of.
There are different types of fungus that cause toenail fungus. Dermatophytes, yeasts, and molds are the most frequent forms of fungus to infect the toenail. Dermatophytes are the most common among the three. Symptoms associated with fungal nails include the discoloration of the toenail, brittleness, and in some circumstances, a smell. Pain is rarely a symptom caused by toenail fungus.
Diagnosis of fungal nails is generally a rather quick process. However podiatrists will make sure that the cause is not another condition such as lichen planus, psoriasis, onychogryphosis, or nail damage. Podiatrists will make use of fungal cultures and microscopy to verify that it is fungus.
While over-the-counter ointments are readily available, most are ineffective. This is due to the fact that the nail is very protective and that the fungus slips in between the nail plate and bed. Podiatrists can offer oral medication which currently provides the best results.
Ultimately, prevention is the best line of defense against toenail fungus. Avoid unsanitary public showers. If you do use a public shower, use shower shoes to provide your foot with protection. Once you are finished showering, make sure to thoroughly dry your feet. Fungi thrive in warm, dark, and moist places like sweaty, warm feet that are left dark in shoes all day.
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.
Many pregnant women complain about foot pain while they are expecting. Foot pain can primarily be caused by weight gain and hormonal changes taking place in the body. By understanding how pregnancy impacts the health of a woman's feet, a pregnant woman can take action to keep her feet as healthy and comfortable as possible.
Because a woman's weight changes during pregnancy, more pressure is brought to bear on both the legs and the feet. This weight shift can cause two major foot problems: over-pronation, also known as flat feet, as well as edema, which is swelling of the feet. Over-pronation occurs when the arch of the foot flattens, causing the foot to roll inwards when the individual is walking, and can aggravate the plantar fascia tissues located along the bottom of the feet. If these tissues become inflamed, a pregnant woman can experience pain in the heel of the foot as well as severe foot pain while walking or standing. Swelling of the feet, or edema, often occurs in the later stages of pregnancy. It is caused by slow circulation and water retention, and may turn the feet a light purple color.
To keep feet in good health and prevent over-pronation, pregnant women should avoid walking barefoot and be sure they are wearing shoes that offer good arch support. A device known as an orthotic can be added to regular footwear in order to provide additional support for the feet during pregnancy. Any expectant mother whose feet hurt should first check to see if the shoes she is wearing are old, worn out and not offering the proper support necessary for distributing the weight of her body during pregnancy.
To treat edema of the feet, a good start is to wear quality footwear which offers support and good circulation. Keep feet elevated whenever possible by using a foot stool while seated. Stay well hydrated by drinking plenty of water to prevent water retention in the feet. Any swelling that occurs in only one foot should be examined as soon as possible by a doctor.
Good foot health during pregnancy can help expectant mothers avoid foot pain that leads to other health problems. Massaging the feet and doing regular gentle exercise like walking aids foot health by contributing to good circulation. Supportive shoes are also a good investment that will support foot health during pregnancy.
