Foot pain is sometimes an early sign of rheumatoid arthritis, an autoimmune condition that causes inflammation in the joints. Unlike wear and tear osteoarthritis, rheumatoid arthritis often affects both feet and can involve the toes, midfoot, ankles, and surrounding soft tissues. People may notice stiffness that is worse in the morning, swelling, warmth, or pain that improves slowly with movement. Over time, inflammation can lead to joint deformities, changes in walking patterns, and increased pressure on certain areas of the foot. Early recognition is important because rheumatoid arthritis can progress and affect daily mobility. Wearing supportive footwear, custom orthotics, and activity modifications may help reduce strain on painful joints. When foot pain, swelling, or stiffness persists, it is suggested that you see a podiatrist for an evaluation, diagnosis, and appropriate treatment. Coordinated care with a rheumatologist is often part of long-term management. 

Because RA affects more than just your joints, including the joints in your feet and ankles, it is important to seek early diagnosis from your podiatrist if you feel like the pain in your feet might be caused by RA. For more information, contact one of our podiatrists of William Street Podiatry. Our doctors will assist you with all of your podiatric concerns.

What Is Rheumatoid Arthritis?

Rheumatoid Arthritis (RA) is an autoimmune disorder in which the body’s own immune system attacks the membranes surrounding the joints. Inflammation of the lining and eventually the destruction of the joint’s cartilage and bone occur, causing severe pain and immobility.

Rheumatoid Arthritis of the Feet

Although RA usually attacks multiple bones and joints throughout the entire body, almost 90 percent of cases result in pain in the foot or ankle area.

Symptoms

• Swelling and pain in the feet
• Stiffness in the feet
• Pain on the ball or sole of feet
• Joint shift and deformation

Diagnosis

Quick diagnosis of RA in the feet is important so that the podiatrist can treat the area effectively. Your doctor will ask you about your medical history, occupation, and lifestyle to determine the origin of the condition. Rheumatoid Factor tests help to determine if someone is affected by the disease.

In ballet, the bones of the foot work together to create strength, grace and precise control. Proper alignment allows dancers to move smoothly while maintaining balance and stability. In first position, the feet turn outward from the hips with the heels close together, creating a stable base that requires even weight distribution through the foot bones. In second position, the feet remain turned outward, but are spaced apart increasing the base of support and allowing greater balance, movement and freedom. These positions rely on coordinated function of the bones, joints, and muscles to manage space and control body weight. A podiatrist can help dancers by evaluating foot mechanics, addressing pain, and preventing injury through supportive care. If foot discomfort affects your dancing, it is suggested that you consult a podiatrist who can provide effective relief techniques, enabling you to dance freely again. 

If you have any concerns about your feet, contact one of our podiatrists from William Street Podiatry. Our doctors 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.

Athlete’s foot is a common fungal infection that affects the skin on the feet, usually starting between the toes. It thrives in warm and moist environments and can cause itching, redness, burning, and peeling. If not treated, the infection can spread to other parts of the body, including the toenails, hands, and groin. Risk factors include wearing damp socks, using shared showers, having sweaty feet, and walking barefoot in public places. A podiatrist can help by diagnosing the infection, providing effective treatments, and offering guidance to prevent it from returning. Professional care can also address complications such as cracked skin or nail involvement. If you notice signs of athlete’s foot, it is suggested that you consult a podiatrist who can offer effective treatment solutions, which may include prescribed medication.

Athlete’s Foot

Athlete’s foot is often an uncomfortable condition to experience. Thankfully, podiatrists specialize in treating athlete’s foot and offer the best treatment options. If you have any questions about athlete’s foot, consult with one of our podiatrists from William Street Podiatry. Our doctors will assess your condition and provide you with quality treatment.

What Is Athlete’s Foot?

Tinea pedis, more commonly known as athlete’s foot, is a non-serious and common fungal infection of the foot. Athlete’s foot is contagious and can be contracted by touching someone who has it or infected surfaces. The most common places contaminated by it are public showers, locker rooms, and swimming pools. Once contracted, it grows on feet that are left inside moist, dark, and warm shoes and socks.

Prevention

The most effective ways to prevent athlete’s foot include:

• Thoroughly washing and drying feet
• Avoid going barefoot in locker rooms and public showers
• Using shower shoes in public showers
• Wearing socks that allow the feet to breathe
• Changing socks and shoes frequently if you sweat a lot

Symptoms

Athlete’s foot initially occurs as a rash between the toes. However, if left undiagnosed, it can spread to the sides and bottom of the feet, toenails, and if touched by hand, the hands themselves. Symptoms include:

• Redness
• Burning
• Itching
• Scaly and peeling skin

Diagnosis and Treatment

Diagnosis is quick and easy. Skin samples will be taken and either viewed under a microscope or sent to a lab for testing. Sometimes, a podiatrist can diagnose it based on simply looking at it. Once confirmed, treatment options include oral and topical antifungal medications.

Measuring your foot is a simple way to ensure proper shoe fit and avoid discomfort. To measure length, place your heel against a wall and mark the tip of your longest toe, then measure the distance. To measure width, wrap a soft tape measure around the widest part of your foot, and then use a conversion chart to determine the correct shoe size. Wearing shoes that do not fit properly can lead to blisters, bunions, corns, hammertoes, and even long-term joint pain. A podiatrist can assess your foot shape, gait, and any underlying conditions while recommending supportive shoes or custom orthotics for comfort and protection. If you have foot pain from wearing the wrong shoes, it is suggested that you consult a podiatrist who can treat various foot conditions, and guide you on additional tips for finding your right shoe size.

Getting the right shoe size is an important part of proper foot health. Seek the assistance of one of our podiatrists from William Street Podiatry. Our doctors will provide the care you need to keep you pain-free and on your feet.

Getting the Right Shoe Size

There are many people who wear shoes that are the incorrect size, negatively affecting their feet and posture. Selecting the right shoes is not a difficult process, so long as you keep several things in mind when it comes to choosing the right pair.

• When visiting the shoe store, use the tools available to measure your foot.
• Be sure there is ‘wiggle room’. There should be about an inch between your toes and the tip of your shoes.
• Do not always assume you are the same size, as manufacturers run differently.
• Purchase shoes later in the day, as your feet swell as the day progresses.
• If a shoe is not comfortable, it is not suitable. Most shoes can’t be ‘broken in’, and comfort should be the ultimate goal when it comes to choosing the right pair of shoes

As our feet hold our body weight and keep us moving, it is important to treat them right. Picking the right pair of shoes can provide your feet comfort and mobility without pain.
