How to Deal with Athlete's Foot

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.

Various Causes of Ankle Pain

Ankles are joints that connect bones in the feet with bones in the lower leg. They are comprised of bones, ligaments, muscles, tendons, blood vessels, and nerves. The ankle joint allows the foot to move side-to-side, as well as up-and-down.

Ankle pain can be caused by a variety of conditions, but is most commonly due to soft tissue injuries such as ankle sprains and strains. 

An ankle sprain occurs when one or more of the strong ligaments that support and stabilize the ankle become overly stretched or even torn if the ankle rolls, turns, or twists awkwardly. Depending on the grade of sprain (mild-moderate-severe), there will be varying degrees of pain, swelling, and restricted range of motion, along with tenderness, bruising, and ankle instability. There may even be an audible popping noise at the moment of injury.

Ankle strains can sometimes produce similar symptoms of pain, swelling, and loss of motion, however, they are due to overly stretched muscles and tendons—not ligaments. Ankle strains may also cause muscle cramps in the feet, calves and shins.

Ankle fractures are another common source of ankle pain and occur one or more of the three bones in the ankle become fractured (broken). These breaks can be stress fractures (due to repetitive stress) or traumatic fractures (due to an acute injury). Depending on where and how severe the fracture is, symptoms can include pain and swelling that can sometimes spread up to the knee, bruising or discoloration, and an inability to bear weight. A visible deformity or exposed bone may occur in severe fractures.

Various forms of arthritis may also cause ankle pain. Rheumatoid arthritis (RA) causes the immune system to attack healthy joints, like the ankle joint, by mistake, causing stiffness and swelling in both ankles. Osteoarthritis occurs when cartilage covering the ends of bones wears down, causing the bones to rub against each other. This results in pain, stiffness, and reduced range of motion in the ankle. Gout is a form of arthritis where excess amounts of uric acid in the bloodstream crystallize and build up on joints, causing severe pain and swelling. Reactive arthritis causes joint pain and swelling in the ankle in response to an infection in another part of the body.

Other forms of ankle pain include bursitis (an inflammation of a cushioning bursa sac between tendons and bone), scleroderma (a thickening of connective tissues), chronic ankle instability (caused by improperly healed ankle sprains), Achilles tendon injuriesflat feet, or an infection in the ankle.

Foot and Ankle Surgery

When conservative, noninvasive methods prove ineffective, surgery may be selected as the next course of action for the treatment of your foot or ankle condition.  A wide number of foot and ankle surgical procedures exist, and it is up to your podiatrist to determine which intervention will be most appropriate and helpful for your case.  Some surgical procedures include bunion surgery, fusion, hammertoe surgery, heel spur surgery, metatarsal surgery, nail surgery, neuroma surgery, reconstructive surgery, skin surgery, and tendon surgery.  Typically, surgery is turned to as a definitive way to alleviate excessive pain or discomfort and to return your foot to full mobility.

Regardless of the location on the body, all surgical procedures require preoperative testing and examination to ensure the surgery’s success and preferred outcome.  A review of your medical history and medical conditions will take place, as will an evaluation of any current diseases, illnesses, allergies, and medications.  Tests such as blood studies, urinalyses, EKG, X-rays, and blood flow studies may be ordered.  Because the procedure involves the foot and/or ankle, the structures of your feet while walking may also be observed by your podiatrist.

Care post-surgery will depend on the type of surgical procedure performed.  Typically, all postoperative care involves rest, ice, compression, and elevation.  To improve and ensure a safe recovery, your foot and ankle surgeon may also employ the use of bandages, splints, surgical shoes, casts, crutches, or canes.  He will also determine if and when you can bear weight.  A timely and thorough recovery is a priority for both you and your podiatrist, and carefully following postoperative instructions can help achieve this.  

What is Morton's Neuroma?

Morton’s neuroma, (also referred to as Morton’s metatarsalgia, Morton’s neuralgia, plantar neuroma or intermetatarsal neuroma) is a condition that is caused when the tissue around one of the nerves between your toes begins to thicken. This thickening can result in pain in the ball of the foot. Fortunately, the condition itself is not cancerous.

Morton’s neuroma affects women more often than men with a ratio of 4:1. It tends to target women between the age of 50 and 60, but it can occur in people of all ages. There are some risk factors that may put you at a slightly higher risk of developing the condition. People who often wear narrow or high-heeled shoes are often found to be linked to Morton’s neuroma. Additionally, activities such as running or jogging can put an enormous amount of pressure on the ligament and cause the nerve to thicken.

There usually aren’t any outward symptoms of this condition. A person who has Morton’s neuroma may feel as if they are standing on a pebble in their shoe. They may also feel a tingling or numbness in the toes as well as a burning pain in the ball of their foot that may radiate to their toes.

In order to properly diagnose you, the doctor will press on your foot to feel for a mass or tender spot. He may also do a series of tests such as x-rays, an ultrasound, or an MRI. X-rays are usually done to rule out any other causes for your foot pain such as a stress fracture. Ultrasounds are used to reveal soft tissue abnormalities that may exist, such as neuromas. Your podiatrist may want to use an MRI in order to visualize your soft tissues.

There are three main options for treatment of Morton’s neuroma: Injections, decompression surgery, and removal of the nerve. Injections of steroids into the painful area have been proven to help those with Morton’s neuroma. Decompression surgery has been shown to relieve pressure on the affected nerve by cutting nearby structures such as the ligaments in the foot. Another treatment option would be to surgically remove the growth to provide pain relief.

If you suspect that you have Morton’s neuroma you should make an appointment with your podiatrist right away. You shouldn’t ignore any foot pain that lasts longer than a few days, especially if the pain does not improve.

Ingrown Toenail Care

An ingrown toenail is a nail that has curved downward and grows into the skin.  This typically occurs at the nail borders, or the sides of the nail.  As a result, pain, redness, swelling, and warmth may occur in the toe.  If a break in the skin forms due to the ingrown nail, bacteria may enter and cause an infection in the area; this is typically characterized by a foul odor and drainage.

Ingrown toenails have multiple reasons for developing.  In many instances, the condition is a result of genetics and is inherited.  The most common cause, however, is improper trimming; cutting the toenails too short forces the skin beside the nail to fold over.  An ingrown toenail can also develop due to trauma, such as stubbing the toe, having an object fall on the toe, or participating in activities that involve repeated kicking or running.  Wearing shoes that are too tight or too short can also cause ingrown toenails.

Treatment for an ingrown toenail varies between patients and the severity of the condition.  Milder cases that don’t involve infection or other medical conditions can benefit from soaking the feet in room-temperature water and gently massaging the side of the nail.  In most cases, however, it is best to see your podiatrist for thorough and proper treatment.  After examining your toe, your podiatrist may prescribe oral antibiotics to clear the infection if one is present.  Surgical removal of either a portion of the nail or the entire nail may also be considered.  In some cases, complete removal or destruction of the nail root may be required.  Most patients who undergo nail surgery experience minimal pain afterward and can return to normal activity the following day.

Ingrown toenails can be prevented with proper nail trimming and by avoiding improper-fitting shoes.  When cutting the toenails, be sure that you are cutting in a straight line and avoid cutting them too short.  Shoes should not be too short or tight in the toe box.
