A friction blister is a repetitive injury, usually the result of doing a motion that threatens the skin. Feet and toes are among the most common sites for friction blisters. Pressure, friction, and damp or moist skin create the prime environment for a friction blister formation. For instance, a runner or hiker wearing new or stiff shoes but no moisture-wicking socks may be at risk. These factors may result in the separation of skin layers, causing a plasma-like fluid to build up under the top layer in an effort to protect those beneath it. What you will see is a bubble-like formation on the skin. The normal reaction is to pop it and drain the fluid, but that action could lead to more pain and possible infection. The fluid bubble is considered sterile, and experts recommend leaving it alone. Blisters will usually go away on their own if you cease the harming action. A protective, donut-shaped pad, to protect the site, may help. However, if the friction blister site becomes red and swollen, and emits an odor, it may be infected. In that case, it is wise to consult a podiatrist as soon as possible for treatment. 

Blisters may appear as a single bubble or in a cluster. They can cause a lot of pain and may be filled with pus, blood, or watery serum. If your feet are hurting, contact Dr. John R. Northrup of Superior Podiatry. Our doctor can provide the care you need to keep you pain-free and on your feet.

Foot Blisters

Foot blisters are often the result of friction. This happens due to the constant rubbing from shoes, which can lead to pain.

What Are Foot Blisters?

A foot blister is a small fluid-filled pocket that forms on the upper-most layer of the skin. Blisters are filled with clear fluid and can lead to blood drainage or pus if the area becomes infected.

Symptoms

(Blister symptoms may vary depending on what is causing them)

• Bubble of skin filled with fluid
• Redness
• Moderate to severe pain
• Itching

Prevention & Treatment

In order to prevent blisters, you should be sure to wear comfortable shoes with socks that cushion your feet and absorb sweat. Breaking a blister open may increase your chances of developing an infection. However, if your blister breaks, you should wash the area with soap and water immediately and then apply a bandage to the affected area. If your blisters cause severe pain it is important that you call your podiatrist right away.

The arch contributes to making the human foot stiff. Medical research has indicated there are two arches,the MLA (medial longitudinal arch) and the TTA (transverse tarsal arch). The middle of the foot contains the TTA, and covers the width of the foot. The TTA plays a more significant role in how stiff the foot is. The MLA runs on the inside of the foot from the heel to the toes. Each foot is made up of 26-28 bones, and together they account for nearly a quarter of the bones in the body. The plantar fascia is found within the MLA, and is responsible for 25 percent of foot stiffness. There is a test that is performed on cadaveric feet, known as the three-point bending test. This involves cutting the tissue between the long bones of the feet, known as the metatarsals. When the tissue is severed, the stiffness in the foot is reduced by half. Patients who are interested in learning more about the arch and foot structure may wish to speak with a podiatrist for more information.

If you have any concerns about your feet, contact Dr. John R. Northrup from Superior Podiatry. Our doctor can provide the care you need to keep you pain-free and on your feet.

Biomechanics in Podiatry

Podiatric biomechanics is a particular sector of specialty podiatry with licensed practitioners who are trained to diagnose and treat conditions affecting the foot, ankle and lower leg. Biomechanics deals with the forces that act against the body, causing an interference with the biological structures. It focuses on the movement of the ankle, the foot and the forces that interact with them.

A History of Biomechanics

• Biomechanics dates back to the BC era in Egypt where evidence of professional foot care has been recorded.
• In 1974, biomechanics gained a higher profile from the studies of Merton Root, who claimed that by changing or controlling the forces between the ankle and the foot, corrections or conditions could be implemented to gain strength and coordination in the area.

Modern technological improvements are based on past theories and therapeutic processes that provide a better understanding of podiatric concepts for biomechanics. Computers can provide accurate information about the forces and patterns of the feet and lower legs.

Understanding biomechanics of the feet can help improve and eliminate pain, stopping further stress to the foot.

Tarsal coalition is a congenital condition where two bones of the foot are connected. The hindfoot is composed of the talus, calcaneus, cuboid, navicular and cuneiform bones. When two of these bones grow together, usually connected by a bridge of cartilage, it is known as a tarsal coalition. The two most common sites are between the calcaneus and navicular bones, or between the talus and calcaneus bones. Though a tarsal coalition usually begins in the womb, it often is not detected until early adolescence. At that point the child’s foot may become stiff and painful, and their daily activities may be more difficult to perform. Symptoms include stiff, painful feet and a rigid flat foot that makes it hard to walk. A limp can develop with higher levels of activity. Many people do not experience symptoms from a tarsal coalition until later in life, usually because another condition, like arthritis, makes it more apparent. A podiatrist can examine your child’s foot with X-rays and other imaging tests to detect the location and severity of the coalition. A number of non-surgical treatments are available, including orthotics, a boot or cast, and injections. In certain cases, surgery may be an option. If your child is complaining of heel pain or is exhibiting any of the above symptoms, please contact a podiatrist for an exam and a diagnosis. 

The health of a child’s feet is vital to their overall well-being. If you have any questions regarding foot health, contact Dr. John R. Northrup of Superior Podiatry. Our doctor can provide the care you need to keep you pain-free and on your feet.

Tips for Keeping Children's Feet Healthy

• Make sure their shoes fit properly
• Look for any signs of in-toeing or out-toeing
• Check to see if they have Clubfoot (condition that affects your child’s foot and ankle, twisting the heel and toes inward) which is one of the most common nonmajor birth defects.
• Lightly cover your baby’s feet (Tight covers may keep your baby from moving their feet freely, and could prevent normal development)
• Allow your toddler to go shoeless (Shoes can be restricting for a young child’s foot)
• Cut toenails straight across to avoid ingrown toenails
• Keep your child’s foot clean and dry
• Cover cuts and scrapes. Wash any scratches with soap and water and cover them with a bandage until they’ve healed.

Toenails protect the toes. They are made of keratin, which makes them tough and resilient for the daily wear and tear they endure. Various things, including friction from ill-fitting shoes, level of physical activity, some pre-existing health conditions, temperature, and moisture, can affect toenails. Pain, itching, and discoloration are some of the signs of toenail problems. Toenail fungus, or onychomycosis, is a common toenail problem. It is more apt to affect older people, with half of all people over 70 developing a toenail fungal infection. It can also impact those who walk barefoot in public areas, like pool areas or locker rooms (with warm, dark, and damp conditions), and those who get sweaty feet or have diabetes. As the infection makes its way deeper into the toenail, the nail becomes discolored and thickened. The nail may crumble and become jagged at the edge. The infection can spread to other toenails and surrounding skin. If it oozes a foul-smelling pus, the infection is worse. It is important to see a podiatrist if you feel you have toenail fungus or any other troubling issues with your toenails. They can properly diagnose the problem and discern how it should be treated.

If left untreated, toenail fungus may spread to other toenails, skin, or even fingernails. If you suspect you have toenail fungus it is important to seek treatment right away. For more information about treatment, contact Dr. John R. Northrup of Superior Podiatry. Our doctor can provide the care you need to keep you pain-free and on your feet.

Symptoms

• Warped or oddly shaped nails
• Yellowish nails
• Loose/separated nail
• Buildup of bits and pieces of nail fragments under the nail
• Brittle, broken, thickened nail

Treatment

If self-care strategies and over-the-counter medications does not help your fungus, your podiatrist may give you a prescription drug instead. Even if you find relief from your toenail fungus symptoms, you may experience a repeat infection in the future.

Prevention

In order to prevent getting toenail fungus in the future, you should always make sure to wash your feet with soap and water. After washing, it is important to dry your feet thoroughly especially in between the toes. When trimming your toenails, be sure to trim straight across instead of in a rounded shape. It is crucial not to cover up discolored nails with nail polish because that will prevent your nail from being able to “breathe”.

In some cases, surgical procedure may be needed to remove the toenail fungus. Consult with your podiatrist about the best treatment options for your case of toenail fungus.
