Athlete’s foot is a type of fungal infection that affects the skin on the feet. It is caused when the tinea fungus grows on the foot. It is possible to catch the fungus through direct contact with someone who has it or by touching a surface that is contaminated with it. This type of fungus thrives in warm, moist environments such as showers, locker room floors, and swimming pools. Your risk of getting it may also increase by wearing tight-fitting, closed-toe shoes, or by having sweaty feet.

Symptoms of athlete’s foot include itching, stinging or burning sensations between the toes. You may also experience toenails that are discolored, thick, crumbly, or toenails that pull away from the nail bed.

Your podiatrist may diagnose athlete’s foot by detecting these symptoms or by doing a skin test to see if there is a fungal infection present. The most common exam used to detect Athlete’s foot is a skin lesion potassium hydroxide exam. To use this method, your doctor will scrape off a small area of the infected skin and place it into potassium hydroxide. The potassium hydroxide will destroy the normal cells and leave the fungal cells untouched so that they are visible under a microscope.

There are a variety of treatment options for athlete’s foot. Some medications are miconazole (Desenex), terbinafine (Lamisil AT), clotrimazole (Lotrimin AF), butenafine (Lotrimin Ultra), and tolnaftate (Tinactin). While these options may be able to treat your fungus, it is best that you consult with a podiatrist in order to see which treatment option may work best for you.

In some cases, Athlete’s foot may lead to complications. A severe complication would be a secondary bacterial infection which may cause your foot to become swollen, painful, and hot.

There are ways that you can prevent athlete’s foot. Washing your feet with soap and water each day and drying them thoroughly is an effective way to prevent infections. You also shouldn’t share socks, shoes, or towels with other people. It is crucial that you wear shower sandals in public showers, around swimming pools, and in other public places. Additionally, you should make sure you wear shoes that can breathe and change your socks when your feet become sweaty. If you suspect that you have Athlete’s foot, you should seek help from a podiatrist as soon as possible.

Flatfoot is a foot disorder that is not as straightforward as many people believe.  Various types of flatfoot exist, each with their own varying deformities and symptoms.  The partial or total collapse of the arch, however, is a characteristic common to all types of flatfoot.  Other signs of flatfoot include:

• “Toe drift,” or the pointing outward of the toes and the front part of the foot
• The tilting outward of the heel and the tilting inward of the ankle
• The lifting of the heel off the ground earlier when walking due to a tight Achilles tendon
• Hammertoes
• Bunions

One of the most common types of flatfoot is flexible flatfoot.  This variation usually starts in childhood and progresses as one ages into adulthood.  Flexible flatfoot presents as a foot that is flat when standing, or weight-bearing.  When not standing, the arch returns.  Symptoms of flexible flatfoot include:

• Pain located in the heel, arch, ankle, or along the outside of the foot
• Overpronation, or an ankle that rolls in
• Shin splint, or pain along the shin bone
• General foot aches or fatigue
• Pain located in the lower back, hip, or knee

Your podiatrist will most likely diagnose flatfoot by examining your feet when you stand and sit.  X-rays may be taken to define the severity and help determine the treatment option best for your condition.  Nonsurgical treatments can include activity modification, weight loss, orthotics, immobilization, medications, physical therapy, shoe modifications, and ankle foot orthoses (AFO) devices.  If nonsurgical methods prove ineffective, surgery may be considered.  Multiple surgical procedures can correct flatfoot; and depending on your specific condition, one may be selected alone or combined with other techniques to ensure optimal results.

A bunion is a bump that forms at the base of the big toe. Bunions form when the big toe pushes against the next toe, which forces the big toe joint to get bigger and stick out.  As a result, the skin over the bunion may start to appear red and it may feel sore.

There are risk factors that can increase your chances of developing bunions. People who wear high heels or ill-fitting shoes are more likely to develop them, in addition to those who have a genetic history of bunions or have rheumatoid arthritis.

The most obvious way to tell if you have a bunion is to look for the big toe pushing up against the toe next to it. Bunions produce a large protrusion at the base of the big toe and may or may not cause pain. Other symptoms are redness, swelling, and restricted movement of the big toe if you have arthritis. 

Nonsurgical methods are frequently used to treat bunions that aren’t severe. Some methods of nonsurgical treatment are orthotics, icing and resting the foot, taping the foot, and pain medication. Surgery is usually only required in extreme cases. However, if surgery is needed, some procedures may involve removing the swollen tissue from around the big toe joint, straightening the big toe by removing part of the bone, or joining the bones of your affected joint permanently.

Your podiatrist will diagnose your bunion by doing a thorough examination of your foot. He or she may also conduct an x-ray to determine the cause of the bunion and its severity.

An ankle sprain occurs when one or more ankle ligament gets overly stretched. Ligaments are strong bands of tissue that bind and support the bones and other structures that make up the ankle. In more severe ankle sprains, the ligament(s) tear—either partially or completely—and there may be an audible popping noise at the moment of injury.

Ankle sprains are quite common and can occur when the ankle rolls outwardly (eversion) or inwardly (inversion), causing the ligament(s) to stretch beyond normal limits, or even tear. Falls, twists, or blows to the ankle during sports or other activities can cause this injury, as well as wearing improper footwear, running on uneven surfaces, or having weak ankles.

Depending on the injury’s severity, an ankle sprain will be classified as Grade I, Grade II, or Grade III. Grade I sprains involve ligament(s) being overly stretched but not torn, with symptoms of mild pain, swelling, and ankle instability. There may also be some difficulty bearing weight. A Grade II sprain usually involves a partial tear of the ligament which brings more intensity in these symptoms, along with possible bruising. With a Grade III sprain, the ligament is completely torn, the symptoms are severe, and it may not be possible to put weight on the affected foot at all. 

To diagnose and grade an ankle sprain, a podiatrist will perform a physical examination, checking for tenderness and range of motion in the ankle. For more severe sprains, X-rays or other imaging studies may be necessary. 

It is vitally important to have an ankle sprain treated properly as improper healing often leads to future ankle sprains and possibly even chronic ankle stability. Treatment for an ankle sprain will vary, depending on its severity, and may include the RICE method (Rest/Ice/Compression/Elevation), physical therapy, bracing, medications, and possibly even surgery to repair a torn ligament. Rehabilitation is very important for the sprain to heal properly and to restore functionality.

While proper foot care is important for everybody, senior citizens have the tendency to be more susceptible to certain foot conditions. The elderly should therefore be well informed about any problems that may arise and about what they can do to properly avoid or treat them.

Some of the most common foot problems seniors are susceptible to include foot ulcers, ingrown toenails, fallen arches, and fungal nails. A foot ulcer is an open sore on the foot and can be a result of diabetes and decreased sensation in the feet. An ingrown toenail is defined as when the nail grows into the side of the toe. Fallen arches are indicated by the instep of the foot collapsing. A fungal nails is a condition that results in deformed and discolored toenails.

In order to avoid these conditions it is recommended that the feet be inspected by the patient on a regular basis. If these inspections are carried out routinely, there is a good likelihood that problems can be identified before they become severe, or can even be avoided altogether. If any abnormality is discovered, it is important that the individual consult a podiatrist for diagnosis and information on treatment options.

Proper foot hygiene is also important. Making sure that you always have clean, dry socks on can be a major deterrent to many different problems including bacterial infections, foot odor, and certain types of fungus. Wet feet are a major cause of many of these problems.  If your socks get wet, it is important to change them. Walking around in wet socks may not only lead to various infections, but can irritate the skin and result in a number of various complications. Clean, dry feet are less likely to be affected by fungal and other infections.

As people age, the fat present on your feet begins to deteriorate. The protective nature of this fat keeps the feet healthy by providing a barrier between your bones and the ground. This also aids in giving the skin on the feet a certain amount of elasticity. This is one factor that causes elderly people to develop some serious foot issues. Foot moisturizers can be helpful to avoid certain problems associated with this. However, water-based moisturizers do not work as well for elderly people as they do for the young. Instead, it is more effective to use an emollient instead. An emollient is effective because it binds the water in the foot, keeping it from becoming absorbed too readily which will result in dry skin. Emollients also have a special property called occlusion, which provides a layer of oil on the skin. This layer prevents the foot from drying up and can be very effective in treating dry skin disorders.  If you can keep the skin on your feet healthy, this will substantially reduce the number of foot problems you will encounter in old age.

Proper footwear is another way to keep feet healthy. Shoes that fit well and provide proper support help prevent ingrown toenails and fallen arches.

Certain medical conditions such as diabetes or poor blood circulation increase the risk for foot issues. For individuals with any of these conditions it is extremely important to conduct regular foot inspections to make sure that there are no sores or infections present.
