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.

A bunion is an enlargement of the base joint of the toe that connects to the foot, often formed from a bony growth or a patch of swollen tissues. It is caused by the inward shifting of the bones in the big toe, toward the other toes of the foot. This shift can cause a serious amount of pain and discomfort. The area around the big toe can become inflamed, red, and painful.

Bunions are most commonly formed in people who are already genetically predisposed to them or other kinds of bone displacements. Existing bunions can be worsened by wearing improperly fitting shoes. Trying to cram your feet into high heels or running or walking in a way that causes too much stress on the feet can exacerbate bunion development. High heels not only push the big toe inward, but shift one's body weight and center of gravity towards the edge of the feet and toes, expediting bone displacement.

A podiatrist knowledgeable in foot structure and biomechanics will be able to quickly diagnose bunions. Bunions must be distinguished from gout or arthritic conditions, so blood tests may be necessary. The podiatrist may order a radiological exam to provide an image of the bone structure. If the x-ray demonstrates an enlargement of the joint near the base of the toe and a shifting toward the smaller toes, this is indicative of a bunion.

Wearing wider shoes can reduce pressure on the bunion and minimize pain, and high heeled shoes should be eliminated for a period of time. This may be enough to eliminate the pain associated with bunions; however, if pain persists, anti-inflammatory drugs may be prescribed. Severe pain may require an injection of steroids near the bunion. Orthotics for shoes may be prescribed which, by altering the pressure on the foot, can be helpful in reducing pain. These do not correct the problem; but by eliminating the pain, they can provide relief.

For cases that do not respond to these methods of treatment, surgery can be done to reposition the toe. A surgeon may do this by taking out a section of bone or by rearranging the ligaments and tendons in the toe to help keep it properly aligned. It may be necessary even after surgery to wear more comfortable shoes that avoid placing pressure on the toe, as the big toe may move back to its former orientation toward the smaller toes.

An ingrown toenail is a toenail that grows sideways into the nail bed, causing pain and swelling. Ingrown toenails can worsen and cause drainage, turning into a serious infection.

Several factors affect whether a person is at risk from an ingrown toenail. The many causes include being overweight, diabetes, participating in sports, having a fungal infection of the toe, and cutting your nails too short. Ingrown toenails also have a genetic predisposition, causing some people to be more prone to receive the condition than others. Other causes include improperly fitting shoes and shoes that keep the feet damp.

Ingrown toenails can be preventable with certain measures. For starters, allowing your toe nails to grow slightly longer in length will help prevent them from becoming ingrown. If you have already developed an ingrown toenail, soak the affected toe in warm water. This will alleviate the pain and help prevent an infection from forming. Antibiotic soap or Epsom salts may be added to further help the relieving process and avoid infection. Placing cotton beneath the affected area is also suggested, as this may help the toenail grow upwards and not into the nail bed. Swelling and redness can be reduced by resting with your feet elevated.

A podiatrist should be seen if the pain becomes so serious that it prevents you from doing your everyday activities. If a red streak running up your leg appears or if you suspect your infection has spread, contact a podiatrist immediately. Fast treatments can be undertaken to lessen your pain and have you walking comfortably.

An ingrown toenail can be easily treated with a Band-Aid. Simply wrap the affected toe with a Band-Aid to prevent infection and keep the nail from growing out at a painful angle.

In more serious cases, your podiatrist may decide to make a small incision to remove a portion of your toenail. To prevent the nail from growing back, medication will be placed directly into the nail bed. This procedure would be performed under local anesthesia and is a faster method to alleviate discomfort from an ingrown toenail. Post-procedure directions will have you stay off the affected foot for a day. Afterwards, normal activities can be resumed.
