Plantar fibromas occur when benign tumors develop deep inside the plantar fascia, the dense fibrous ligaments that run along the bottom of the foot. The lumps or growths forming along the foot’s arch result in pain that is often felt in various areas of the foot. Plantar fibromas can lead to a multitude of other foot problems as they cause pressure throughout the foot.
Usually, plantar fibromas are diagnosed through a doctor’s examination and x-rays. Sometimes, MRIs are also necessary for proper diagnoses. Nonsurgical treatment options such as orthotics generally do not alleviate the pain caused by plantar fibromas; however, surgery can lead to nerve damage.
