Symptoms:

• Plantar Fibromas are not tender and painful by themselves.
• But it feels like there is a pebble trapped under your skin.
• This causes pain with every step that you take.
• This condition occurs on both sides of the feet in approximately 25% of people.
• Hard, painful bump.
• “Under the skin.”

Causes:

The hard bump on the bottom of my foot is usually due to 4 common causes:

1) Plantar Fibroma:

• A fibroma is a concentration of connective tissue.
• This usually starts with trauma, but can occur for any reason.
• This can feel like a hard pebble just under your skin.
• It can range from 2mm to 5 cm!
• It could be one bump or multiple bumps.
• They are usually non-painful, but as you walk on them, they start to hurt!

2) Plantar Fasciitis:

• Which is the most common source of arch & heel pain in the world.
• Inflammation can cause your arch ligaments to swell.
• This leads to stiff & aching morning pain.
• This is not a very hard lump, but a big swollen hard area.
• This is much more common, but less of a hard lump than a plantar fibroma.

3) Foot Bump Cancer:

• This is very, very rare.
• If you have a hard discrete bump, it is likely a fibroma or plantar fasciitis.
• But even if it is very rare, MRI or X-ray should be done to rule out this very dangerous tumor.

4)Ganglionic Cyst:

This is a picture of a ganglion cyst on the ankle.

• Ganglion cysts are swellings of fluid.
• They are usually near foot joints.
• The most common are the big toe joint, the middle of the foot and the ankle.
• A cyst by definition is a sac filled with fluid and it can feel hard or soft.
• These are usually not dangerous.

What Is A Plantar Fibroma?

If you can feel a “pebble- like mass” it is most likely a plantar fibroma:

• It is a relatively non-dangerous condition that occurs at the bottom of your feet.
• They are most common y in the arch.
• A plantar fibroma is the development of what feels like a pebble of connective tissue.
• They can be small or large.
• It can be one or multiple.

Where Did It Come From?

•  The nodules are extremely slow growing taking months to years before they even begin to irritate you.
• They can occur due to trauma.
• They can occur due to abnormal stress.
• Sometimes they can be genetic.
• They are still not completely understood, but it is the abnormal function of collagen producing cells.
• They are signaled by your immune system to start working.

Plantar Fibroma Treatment:

A plantar fibroma can be treated conservatively or surgically.

Conservative bump on the bottom of the foot treatment:

• Gel cushioning.
• Accomodative orthotics.
• Shoe accomodations.
• Get cutous.
• Pads.

Surgery:

• If the mass is extremely large, surgery is likely your only option.
• You should schedule a visit with an experienced foot doctor or podiatrist immediately for an evaluation.
• Nothing else will work to remove the mass.
