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.

Morton's Neuroma, also called Intermetatarsal Neuroma or Plantar Neuroma, is a condition that affects the nerves of the feet, usually the area between the third and fourth toe. Neuroma refers to a benign growth that can occur in different parts of the body. Morton's Neuroma strictly affects the feet. This condition causes the tissue around the nerves that lead to the toes becoming thick, causing pain in the ball of the foot.

This condition can be caused by injury, pressure or irritation. Normally no lump will be felt, but instead burning pain in the ball of the foot will be experienced. Numbness and tingling may also occur. With the onset of this condition, a person may feel pain when tight or narrow shoes are worn. As the condition worsens, the pain may persist for days, or even weeks.

Persistent foot pain should always be a concern. The foot should be examined by a podiatrist if pain persists longer than a few days with no relief from changing shoes. The earlier the foot is examined and treated, the less chance there will be for surgical treatment.

There are some factors that can play a role in the development of Morton's Neuroma. These include wearing ill-fitting shoes that cause pressure to the toes, such as high heels. Also, high impact exercise may contribute to the cause of this condition. Morton’s Neuroma may also develop if the foot sustains an injury. Another cause includes walking abnormally due to bunions or flat feet. This causes excessive pressure and irritates the tissue. At times, people are affected for no determinable reason.

Podiatrists can alleviate the effects of this condition using a treatment plan to help decrease the pain and heal the foot tissue. Depending upon the severity of the Morton's Neuroma, the treatment plan can vary. For cases that are mild to moderate, treatments may include applying padding to the arch to relieve pressure from the nerve and reduce compression while walking. Ice packs can also help reduce swelling. The podiatrist may also create a custom orthotic device to support the foot and reduce compression and pressure on the affected nerve. The doctor will probably advise against partaking in activities that cause constant pressure on the affected area. They may provide wider shoes to ease the pressure from the toes. If these treatments do not relieve the symptoms of this condition, the doctor may use injection therapy.

Surgical treatment may be recommended by the podiatrist if all other treatments fail to provide relief. Normally, the podiatric surgeon will decide on either a surgical procedure that involves removal of the affected nerve or will choose surgery to release the nerve. After examination, the surgeon will decide on the best approach to treat the problem.

Recovery varies according to the type of surgical procedure. The patient will also be instructed on the best shoe wear to prevent the return of this condition, along with changes to workout routines, if this was a cause. Preventative measures are important in ensuring the condition does not return.

Fungal infection of the toenail, or onychomycosis, typically appears as a gradual change in a toenail’s texture and color that involves brittleness and darkening.  The fungal infection itself occurs beneath the surface of the nail.  Aside from discoloration, other symptoms include the collection of debris beneath the nail plate, white marks on the nail plate, and a foul odor emanating from the nail.  If ignored, the infection can spread into other nails and the skin; in severe cases, it can hinder one’s ability to work or walk. 

The toenails are particularly vulnerable to contracting infection in moist environments where people are likely to be walking barefoot, such as around swimming pools, public showers, and locker rooms.  Fungal infection may also be more likely to occur in nail beds that have been injured, and sufferers of chronic diseases such as diabetes, circulatory problems, or immunodeficiency conditions are particularly prone to developing fungal nails. 

Fungal nails can be primarily prevented by practicing proper hygiene and regularly examining the feet and toes.  Carefully washing the feet with soap and water and thoroughly drying the feet afterwards are essential.  Other tips include wearing shower shoes in public areas, changing shoes and socks daily, keeping toenails clipped at a short length, wearing breathable shoes that fit properly, wearing moisture-wicking socks, and disinfecting home pedicure tools and instruments used to cut nails.

Fungal nail treatment may vary between patients and the severity of the condition.  Your podiatrist may suggest a daily routine of cleansing that spans over a period of time to ease mild infections.  Over-the-counter or prescription antifungal agents may also be prescribed, including topical and/or oral medications.  Debridement, or the removal of diseased nail matter and debris, may also be performed.  In more severe cases, surgical treatment may be needed.  In some instances, the temporary removal of the fungal nail allows for the direct application of a topical antifungal to the nail bed.  In other cases, a chronically painful fungal nail that has not responded to other treatments may be permanently removed; this allows the infection to be cured and avoids the growth of a deformed nail.  

Many people suffer from foot problems because their shoes are poorly fitted. When shopping for a new pair of shoes, fashion usually triumphs over comfortability. A pair of well fitted shoes is essential in preventing foot problems and potential injuries.

Poorly fitted shoes can cause foot issues such as plantar fasciitis, bunions, hammertoes, ingrown toenails, and foot pain. Shoes such as high heels and sandals may cause problems for your feet. These shoes put the foot in an unnatural position for long periods and fail to provide good foot support. It is recommended to not wear either one for an extended period.

When you are trying on shoes, make sure they have enough space for your toes to move around. Shoes shouldn’t be cramped but also shouldn’t have too much room that your foot moves around in them. A snug shoe is a good choice. They should also provide good arch support and cushioning. Athletic shoes tend to offer both good support and cushioning. A degree of flexibility is necessary so they aren’t too stiff or too unsupportive.

If you can wear your shoes for a long period of time without experiencing any discomfort, this is a sign that your shoes fit properly. Do not be too dismayed if the shoe isn’t a perfect fit at first; many shoes take a few days to weeks to properly break in. However don’t expect an uncomfortable shoe to become fitted to your foot.

For those with foot conditions such as flat feet or pronation, orthotics may be helpful or even necessary to prevent foot pain. Orthotics are inserts that are placed in the shoe and provide support and cushioning for the foot. While there are many types of orthotics out there, custom-made orthotics may be necessary depending upon your foot and foot conditions.

Feet change in size over time. It is important to check your foot size over time so that you can make sure you have the perfect fit for your feet. A podiatrist can provide more information on proper shoe fitting and foot orthotics.

Plantar warts are growths that typically appear on the heels or other weight-bearing areas of the feet. These warts are caused by the human papillomavirus (HPV). The virus enters the body through breaks in the skin, such as cuts, that are on the bottom of the feet. Plantar warts are more likely to affect children and teenagers, people with weakened immune systems, people who have a history with plantar warts, and people who walk barefoot in environments exposed to a wart-causing virus.

If you suspect you have plantar warts, you may have the following symptoms: pain or tenderness while walking, a lesion that interrupts the ridges in the skin of your foot, small fleshy lesions on the bottom of the foot, or a callus where a wart has grown inward over a well-defined spot on the skin.

HPV causes plantar warts to form and is very common. There are more than 100 kinds of the virus in existence. However, only a few of them cause warts on the feet. The other types of HPV are likely to cause warts on other parts of the body.

If you have plantar warts, your podiatrist may try different treatment methods depending on your specific case. Some treatments for plantar warts are peeling medicines (salicylic acid), freezing medicines (cryotherapy), or surgical procedures. Laser treatments and vaccines are also used to treat plantar warts.
