Plantar fibromatosis is a non-cancerous condition that causes firm lumps to develop within the plantar fascia. This thick band of tissue runs along the bottom of the foot and supports the arch. The lumps are called plantar fibromas. They may develop in one foot or both feet, and can slowly increase in size. Although plantar fibromatosis is usually not dangerous, it can make walking and standing uncomfortable. Understanding the condition can help you recognize changes early and seek appropriate care.
A plantar fibroma often feels like a small, firm knot beneath the skin. Symptoms may include tenderness, pressure, or aching in the arch. Some people have no pain until the lump is pressed by shoes or while walking. The exact cause of plantar fibromatosis is not fully understood. Repeated stress on the plantar fascia may contribute to tissue changes. Genetics may also play a role. Other possible factors include foot trauma and certain medical conditions.
Risk factors can include a family history of plantar fibromatosis and repeated strain on the feet. A podiatrist will examine the lump and ask about symptoms, activities, and medical history. Imaging, such as an ultrasound or MRI scan, may be recommended when the diagnosis needs confirmation. A podiatrist may recommend supportive footwear, custom orthotics, or padding to reduce pressure on the lump.
When symptoms are persistent, a podiatrist may discuss additional treatment options. These can include injections or other approaches designed to reduce pain and irritation. Surgery may be considered when a fibroma is large or causes significant problems with daily activities. Because plantar fibromas can return after removal, careful evaluation is important before choosing surgery. Paying attention to changes in the arch can help you get treatment before discomfort becomes more limiting. If you have developed a plantar fibroma, it is suggested that you consult a podiatrist for an accurate diagnosis and appropriate treatment.

Plantar Fibroma
A plantar fibroma is a fibrous knot in the arch of the foot. It is embedded in the plantar fascia which is a band of tissue that extends from the heel to the toes along the bottom of the foot. There can be multiple plantar fibromas in the feet at the same time. There are no known causes for this condition. If you have a plantar fibroma, there will be a bump in the arch of your foot that cannot be missed. Any associated pain is most often due to a shoe rubbing against the nodule. Non-surgical options, such as steroid injections, physical therapy, and orthotics should be tried first. Surgery is a last resort and is the only thing that will remove a plantar fibroma entirely. Consult with a podiatrist for a proper diagnosis and to determine the treatment regimen that is right for you.
What Causes a Plantar Fibroma?
While there are no specific causes identified, a plantar fibroma can possibly come from genetic predisposition or the formation of scar tissue that forms from healing the tears in the plantar fascia.
What Are the Symptoms of a Plantar Fibroma?
There will be a noticeable lump in the arch of the foot that may or may not cause pain. If pain is felt, it is typically because a shoe is rubbing up against the lump or when walking or standing barefoot.
Treatment and Prevention
A plantar fibroma will not disappear without treatment, but it can get smaller and be a non-issue. If pain persists, a podiatrist examines the foot and when the arch of the foot is pressed, pain can be felt down to the toes. An MRI or biopsy might be performed to help diagnose or evaluate the plantar fibroma. The following non-surgical options are generally enough to reduce the size and pain of these nodules:
Surgery is considered if the mass increases in size and the patient continues to feel pain after non-surgical methods are tried.

A bunion is a bony bump that forms along the inside of the foot at the base of the big toe. It develops as the big toe begins to lean toward the smaller toes, causing the joint at its base to shift outward. Bunions often develop gradually and may become more noticeable over time. Common symptoms include pain, swelling, and redness around the affected joint. The big toe may also become stiff or difficult to move. Although some bunions cause little discomfort, others can make walking or wearing certain shoes painful. Changes in foot structure and family history can increase the likelihood of developing bunions.
As a bunion progresses, the changing position of the big toe can affect how pressure is distributed across the foot. This may lead to discomfort while walking and make the joint more sensitive to pressure from footwear. Some people develop hardened skin over the bunion or experience pain in nearby toes. Arthritis can also affect the big-toe joint and contribute to stiffness. Because bunions can worsen over time, persistent symptoms should be professionally evaluated. An examination can determine the severity of the deformity and identify other foot problems that may be contributing to pain or difficulty walking.
A podiatrist can evaluate a bunion by examining the foot, big-toe position, and joint movement. X-rays may be recommended to measure changes in alignment and assess the condition of the joint. Podiatric treatment depends on the severity of the bunion and how much it affects daily activities. Care may focus on reducing pressure, improving foot function, and managing discomfort. For severe bunions that continue to cause significant problems, surgery may be considered to correct the position of the toe. If bunion pain, swelling, or stiffness is making walking or wearing shoes uncomfortable, it is suggested that you consult a podiatrist for an evaluation and appropriate treatment options.

What Is a Bunion?
A bunion is formed of swollen tissue or an enlargement of boney growth, usually located at the base joint of the toe that connects to the foot. The swelling occurs due to the bones in the big toe shifting inward, which impacts the other toes of the foot. This causes the area around the base of the big toe to become inflamed and painful.
Why Do Bunions Form?
Genetics – Susceptibility to bunions are often hereditary
Stress on the feet – Poorly fitted and uncomfortable footwear that places stress on feet, such as heels, can worsen existing bunions
How Are Bunions Diagnosed?
Podiatrists often perform two tests – blood tests and x-rays – when trying to diagnose bunions, especially in the early stages of development. Blood tests help determine if the foot pain is being caused by something else, such as arthritis, while x-rays provide a clear picture of your bone structure to your provider.
