What’s This Lump on My Arch?

The thick band of elastic tissue that connects your heel bone to the toes is called the plantar fascia. When a benign mass forms and becomes embedded into this plantar fascia, it’s called plantar fibroma.

Introduction

Let’s face it, the bottoms of our feet take a lot everyday from all the walking, running, climbing, and exercise we do. So even a small structural change, like a lump in your arch, can have an effect on the way you walk, and the pain or discomfort you experience. At first it may seem like a tight knot, but if it persists or gets larger, it could be a sign of plantar fibroma.

What’s plantar fibroma?

The thick band of elastic tissue that connects your heel bone to the toes is called the plantar fascia. When a benign mass forms and becomes embedded into this plantar fascia, it’s called plantar fibroma. Small lumps may be only half an inch in size and be completely painless, but if they grow, it can lead to pain, tight calves, and discomfort.

How is it different from plantar fasciitis?

You may be more familiar with plantar fasciitis, which is inflammation of the plantar fascia without a mass formation. While the most common symptom associated with plantar fasciitis is heel pain, plantar fibroma can lead to pain in the middle of the foot.

How is it treated?

The first step in treatment is to get a proper diagnosis from a podiatrist. Plantar fibromas are typically diagnosed through physical examination, biopsies, or imaging including MRIs or X-rays.

Treatments for plantar fibroma include:

  • Physical therapy – stretching and strengthening the foot can help break up the nodules and reduce pain.
  • Custom orthotics – creating custom orthotics can provide additional support around the arch.
  • Medications – Topical and/or oral medications may be used to reduce pain or size of mass.
  • Cortisone injections – injections may be used if pain is severe and persistent.
  • Surgery – If the above treatments do not help, a podiatrist can surgically remove the mass.
