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.
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.
