Patients who notice a lump on the sole of their foot will often visit a podiatrist for a proper diagnosis. It may be a plantar fibroma, which develops in the plantar fascia along the bottom of the foot. A plantar fibroma is considered to be a rare and benign condition but it can be painful as shoes that are worn press against the offending lump. Additionally, pain and discomfort may be felt when standing for extended periods, or when walking barefoot. Research has indicated there is no cure for this condition so many patients will take steps to reduce the pain. This may be achieved by using oral or injected steroids, in addition to extracorporeal shockwave therapy, known as ESWT. If you have this condition, it is strongly urged that you are under the care of a podiatrist who can determine the best course of treatment. 

A plantar fibroma may disrupt your daily activities. If you have any concerns, contact one of our podiatrists of Fox Valley Foot and Ankle Specialists. Our doctors can provide the care you need to keep you pain-free and on your feet.

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.
