Mueller-Weiss Disease and Midfoot Pain

Mueller-Weiss disease is a rare foot condition that affects the navicular bone in the midfoot. It can lead to ongoing pain and changes in foot structure. The navicular bone helps in shock absorption and stability during movement. It is believed to develop when the bone does not receive enough blood flow and is placed under uneven pressure, which may cause it to weaken. People with this condition often notice aching or stiffness in the middle of the foot, especially while walking or during activity. Risk factors include unusual foot mechanics, repetitive stress, or developmental factors affecting the bone. Without proper care, symptoms can gradually worsen and impact daily mobility. A podiatrist can carefully evaluate the foot, confirm the diagnosis with imaging, and create a treatment plan that may include supportive devices or activity changes. If midfoot pain continues, it is suggested that you consult a podiatrist who can offer effective relief and management tips.
Some foot conditions may require additional professional care. If you have any concerns, contact John Mccain, DPM of Advanced Foot & Ankle Specialists, PA. Our doctor can provide the care you need to keep you pain-free and on your feet.
Rare Foot Conditions
The majority of foot conditions are common and can be treated by a podiatrist. Standard diagnostic procedures are generally used to identify specific conditions and treatment can be rendered. A podiatrist also treats rare foot conditions which can be difficult to diagnose and may need extra attention and care.
There are many rare foot conditions that can affect children. Some of these can include:
- Freiberg’s disease
- Kohler’s disease
- Maffucci syndrome
Freiberg’s disease - This can be seen as a deterioration and flattening of a metatarsal bone that exists in the ball of the foot. It typically affects pre-teen and teenage girls, but can affect anyone at any age. Symptoms that can accompany this can be swelling, stiffness, and the patient may limp.
Kohler’s disease - This often targets the bone in the arch of the foot and affects younger boys. It can lead to an interruption of the blood supply which ultimately can lead to bone deterioration. The patient may limp or experience tenderness, swelling, and redness.
Maffucci syndrome - This affects the long bones in a child’s foot leading to the development of abnormal bone lesions. They are benign growths and typically develop in early childhood and the bones may be susceptible to breaking.
A podiatrist can properly diagnose and treat all types of rare foot conditions. If your child is affected by any of these symptoms or conditions, please don’t hesitate to call our office so the correct treatment method can begin.

Rare Foot Conditions
A podiatrist will be able to address a variety of rare foot conditions, particularly the ones that affect children. The most common are Kohler’s disease, Maffucci syndrome, and Freiberg’s disease. They can be properly diagnosed by having an X-ray taken, but in more serious cases an MRI may be needed. Kohler’s disease generally affects younger boys and bone deterioration may result from an interruption of blood supply. Children who have Kohler’s disease may find relief when the affected foot is rested, and a special boot is worn. Benign growths in the long bones of a child’s foot may lead to the development of bone lesions, and this is known as Maffucci syndrome. People who have this condition find mild relief when custom-made orthotics are worn. Freiberg’s disease targets the ball of the foot and can typically affect pre-teen and teenage girls. The metatarsal bone becomes deteriorated and flattened, and common symptoms include swelling and stiffness. A cast is often necessary to wear with this disease as it can help to reduce existing pain. Erythromelalgia is a rare foot condition, and its cause is unknown. Symptoms of this disease can include intense burning pain and the feet may appear red or feel warm. Relief may be found when the affected foot is immersed in ice water. It can also be beneficial to elevate the foot frequently. If your child complains of foot pain, it is strongly suggested that you consult with a podiatrist who can diagnose and treat rare foot conditions.
Wound Care
Diabetics must be wary of all wounds, regardless of depth or size. Diabetes, a chronic disease in which the body cannot properly use glucose the way it normally would, causes various complications that make wounds difficult to heal. Nerve damage or neuropathy will cause diabetics to have trouble feeling the pain of a blister or cut until the condition has significantly worsened or become infected. A diabetic’s weakened immune system can make even the most minor of wounds easily susceptible to infection. Diabetics are also more prone to developing narrow, clogged arteries, and are therefore more likely to develop wounds.
Wounds should be taken care of immediately after discovery, as even the smallest of wounds can become infected if enough bacteria build up within the wound. To remove dirt, wounds should be first rinsed under running water only. Soap, hydrogen peroxide, or iodine can irritate the injury and should be avoided. To prevent infection, apply antibiotic ointment to the wound and cover it with a bandage. The bandage should be changed daily. The skin around the wound may be cleaned with soap.
To prevent further exacerbation, see a doctor—especially if you have diabetes. Minor skin conditions can become larger problems if not properly inspected. As the wound heals, make sure to avoid applying pressure to the affected area.
Total Contact Casting for Diabetic Foot Ulcers

Total contact casting is a specialized treatment used to manage diabetic foot ulcers by distributing pressure evenly across the foot and reducing stress on the wound area. It works by enclosing the foot and lower leg in a carefully molded cast that limits movement and promotes healing through constant contact and offloading pressure. This method is highly effective in encouraging ulcer closure while protecting the affected tissue. Risk factors for poor healing include uncontrolled blood sugar, poor circulation, and prolonged pressure on the foot. A podiatrist plays a key role by applying the cast, monitoring healing progress, and adjusting treatment, as needed. If you have diabetes and have developed a foot ulcer, it is suggested that you are under the care of a podiatrist who can discuss the benefits of this treatment method with you.
Wound care is an important part in dealing with diabetes. If you have diabetes and a foot wound or would like more information about wound care for diabetics, consult with John Mccain, DPM from Advanced Foot & Ankle Specialists, PA. Our doctor will assess your condition and provide you with quality foot and ankle treatment.
What Is Wound Care?
Wound care is the practice of taking proper care of a wound. This can range from the smallest to the largest of wounds. While everyone can benefit from proper wound care, it is much more important for diabetics. Diabetics often suffer from poor blood circulation which causes wounds to heal much slower than they would in a non-diabetic.
What Is the Importance of Wound Care?
While it may not seem apparent with small ulcers on the foot, for diabetics, any size ulcer can become infected. Diabetics often also suffer from neuropathy, or nerve loss. This means they might not even feel when they have an ulcer on their foot. If the wound becomes severely infected, amputation may be necessary. Therefore, it is of the upmost importance to properly care for any and all foot wounds.
How to Care for Wounds
The best way to care for foot wounds is to prevent them. For diabetics, this means daily inspections of the feet for any signs of abnormalities or ulcers. It is also recommended to see a podiatrist several times a year for a foot inspection. If you do have an ulcer, run the wound under water to clear dirt from the wound; then apply antibiotic ointment to the wound and cover with a bandage. Bandages should be changed daily and keeping pressure off the wound is smart. It is advised to see a podiatrist, who can keep an eye on it.

Swollen Feet and Ankles and Their Causes

Swollen feet and ankles, also known as edema, occur when fluid builds up in the tissues of the lower extremities. Common causes include standing for long periods of time, high salt intake, and pregnancy, which can increase pressure on blood vessels and lead to fluid retention. Other contributing factors may involve poor circulation, injury, or underlying medical conditions. Risk factors include obesity, a sedentary lifestyle, aging, and certain heart or kidney issues that affect fluid balance. A podiatrist can evaluate the cause of swelling, assess circulation and foot structure, and recommend supportive footwear, compression therapy, and lifestyle modifications to reduce discomfort. Early evaluation is important to rule out serious conditions and improve mobility. If your feet or ankles are consistently swollen, it is suggested that you consult a podiatrist who can offer effective relief solutions.
Swollen feet can be a sign of an underlying condition. If you have any concerns, contact John Mccain, DPM of Advanced Foot & Ankle Specialists, PA. Our doctor can provide the care you need to keep you pain-free and on your feet.
Swollen feet are a common ailment among pregnant women and people who stand or sit for extended periods. Aging may increase the possibility of swollen feet and patients who are obese often notice when their feet are swelling too. There may be medical reasons why swollen feet occur:
- Phlebitis - A condition that causes the veins to become inflamed and can also cause leg pain.
- Liver disease - This may lead to low blood levels of albumin which is a protein. This can cause fluid in the blood to pass into the tissues and several areas of the body can become swollen.
- Heart failure - When the heart doesn’t pump properly the blood that is normally pumped back to the heart can pool in the veins of the legs causing swollen feet.
- Kidney disease - One of the main functions of the kidneys is releasing excess fluid in the body. This type of condition can make it difficult for the kidneys to function properly, and as a result the feet may become swollen.
- Deep-vein thrombosis (DVT)- This is a serious condition where blood clots form in the veins of the legs. They can block the return of blood from the legs to the heart which may cause the feet to swell. It is important to be treated by a podiatrist if this condition is present.
Swollen feet can also be caused by bone and tendon conditions, including fractures, arthritis, and tendinitis. Additionally, there may be skin and toenail conditions and an infection may cause the feet to swell. Patients who take medicine to treat high blood pressure may be prone to getting swollen feet.
Many patients elevate their feet to help relieve the swelling and this is generally a temporary remedy. When a podiatrist is consulted the reason behind the swelling can be uncovered and subsequently treated.

Swelling of the Feet
There are many reasons why patients experience swelling of the feet. It is rather common and may be a side effect of pregnancy or from sitting and standing for most of the day. Gravity could also play a role in the development of swollen feet. It is known that the weight of blood volume in our bodies is exerted on the veins in the legs and feet. The veins may not work as efficiently during the aging process, and this could make the blood flow backward causing swollen feet. Relief may be found when obese patients lose weight, and it may help to engage in compression therapy by wearing compression socks, stockings, or athletic sleeves. This method can release pressure on the feet and ankles which may help to reduce existing swelling. There are patients who have controlled their swollen feet by implementing healthy lifestyle changes. These can consist of reducing salt intake, incorporating a gentle exercise regime into the daily routine, and drinking plenty of fresh water. Swollen feet may be a temporary condition that affects people who travel via airplane or automobile, so it is beneficial to walk as frequently as possible even though it can be difficult. Swelling of the feet can also be indicative of other health issues so it is important to pay attention to any type of chest pain, mental confusion, dizziness, or fever. If you consistently have swollen feet, it is strongly suggested that you consult with a podiatrist who can help determine the cause and how to effectively treat it.
Ankle Fracture? Don’t Wait for Treatment
Everything You Need to Know About Gout
Gout, typically found in diabetic patients, is an unusually painful form of arthritis caused by elevated levels of uric acid in the bloodstream. The condition typically strikes the big joint on the big toe. It has also been known to strike the knees, elbows, fingers, ankles and wrists—generally anywhere that has a functioning, moving joint.
The high level of uric acid in a person’s bloodstream creates the condition known as hyperuricema—the main cause of gout. Genetic predisposition occurs in nine out of ten sufferers. The children of parents who suffer gout will have a two in ten chance of developing the condition as well.
This form of arthritis, being particularly painful, is the leftover uric acid crystallizing in the blood stream. The crystallized uric acid then travels to the space between joints where they rub, causing friction when the patient moves. Symptoms include: pain, redness, swelling, and inflammation. Additional side effects may include fatigue and fever, although reports of these effects are very rare. Some patients have reported that pain may intensify when the temperature drops, such as when you sleep.
Most cases of gout are easily diagnosed by a podiatrist’s assessment of the various symptoms. Defined tests can also be performed. A blood test to detect elevated levels of uric acid is often used as well as an x-ray to diagnose visible and chronic gout.
Treatment for gout simply means eliminating symptoms. Non-steroid anti-inflammatory drugs or NSAIDs (Colchicine and other corticosteroid drugs, etc.) will quell the redness, the swelling, and the inflammation. However, managing your diet, lifestyle changes, and using preventative drugs are all helpful toward fully combating the most severe cases.
Those that lead an inactive lifestyle are at a higher risk for gout. Any amount of exercise decreases the probability of repeat encounters with the condition. Reducing your consumption of red meat, sea food, and fructose-sweetened drinks also reduces the likelihood of chronic gout as well.
Ingesting Vitamin C, coffee, and particular dairy products can help with maintaining a healthy lifestyle. There are new drugs out on the market that inhibit the body’s production of uric acid-producing enzymes. However, reducing or eliminating your overall levels of uric acid is the best remedy to ensuring you lead a gout-free life.
The Difference Between Gout and Pseudogout

Gout and pseudogout are forms of inflammatory arthritis caused by crystal buildup in the joints, leading to pain and swelling. Gout develops from uric acid crystals, often affecting the big toe and causing sudden, intense pain, redness, and warmth. Pseudogout is caused by calcium pyrophosphate crystals and more commonly affects larger joints, such as the ankle or knee, with symptoms that include stiffness, swelling, and discomfort. While both conditions share similar signs, they differ in the type of crystals and underlying causes. Risk factors include aging, joint damage, dehydration, and certain medical conditions. A podiatrist can help by identifying the condition, managing symptoms, and recommending treatment. If you have pain or swelling in your big toe joint or surrounding areas, it is suggested that you seek podiatric care to find relief and prevent future flare-ups.
Gout is a foot condition that requires certain treatment and care. If you are seeking treatment, contact John Mccain, DPM from Advanced Foot & Ankle Specialists, PA. Our doctor will treat your foot and ankle needs.
What Is Gout?
Gout is a type of arthritis caused by a buildup of uric acid in the bloodstream. It often develops in the foot, especially the big toe area, although it can manifest in other parts of the body as well. Gout can make walking and standing very painful and is especially common in diabetics and the obese.
People typically get gout because of a poor diet. Genetic predisposition is also a factor. The children of parents who have had gout frequently have a chance of developing it themselves.
Gout can easily be identified by redness and inflammation of the big toe and the surrounding areas of the foot. Other symptoms include extreme fatigue, joint pain, and running high fevers. Sometimes corticosteroid drugs can be prescribed to treat gout, but the best way to combat this disease is to get more exercise and eat a better diet.

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 injuries, flat feet, or an infection in the ankle.
