A plantar fibroma is a benign growth that develops within the plantar fascia, the thick band of tissue along the bottom of the foot. This condition is part of a group of disorders known as plantar fibromatosis and is characterized by the formation of firm nodules. These growths are non-cancerous, but can cause discomfort, depending on their size and location. Plantar fibromas often develop slowly and may go unnoticed at first, but they can become more noticeable as pressure is applied while walking or standing.
Symptoms of a plantar fibroma include a small, firm lump in the arch of the foot that can be felt through the skin. The growth may be painless in the early stages but can lead to discomfort as it enlarges. Some individuals experience aching or pressure when walking, especially while wearing shoes that press against the arch. The appearance of the fibroma is typically a raised nodule under the skin, and it may feel fixed in place rather than movable. In certain cases, multiple nodules may develop, which can increase discomfort.
The exact cause of a plantar fibromas is not fully understood, but several factors are believed to contribute. Repetitive stress on the foot, minor injuries, and strain on the plantar fascia may play a role in its development. Genetics may also influence the likelihood of developing this condition. Risk factors include high levels of physical activity, prolonged standing, and underlying health conditions that affect connective tissue. Men are more commonly affected than women, and the condition is often seen in middle-aged adults.
Managing plantar fibroma focuses on reducing discomfort and preventing progression. Wearing supportive footwear and custom orthotics can help relieve pressure on the affected area. Monitoring changes in size or pain can help guide treatment decisions. If you have developed a plantar fibroma, it is suggested that you consult a podiatrist for effective management solutions.

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:
- Steroid injections
- Orthotics
- Physical therapy to help apply anti-inflammatory creams on the bump
Surgery is considered if the mass increases in size and the patient continues to feel pain after non-surgical methods are tried.
