Hard Bump on the Bottom of my Foot

Hard Bump On The Bottom Of My Foot

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 to trauma, but can occur for any reason.
  • This can feel like a hard pebble just under your skin.
  • If 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!

A lump on the bottom of your foot is usually a fibroma. This is a thickening of connective tissue at the bottom of your foot.


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.

Even though a foot bump due to cancer at the bottom of the foot is rare, it should be ruled out.

4)Ganglionic Cyst:

  • 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.

A fibroma can occur anywhere in the body, but it is most annoying as a hard bump on the bottom of the foot. Although this may be worse cosmetically!

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.

Collagen is a hard protein that makes connective tissue. The abnormal growth can produce a fibroma.



Symptoms of a Hard Bump on the Bottom of My Foot:

  • 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”.



Plantar Fibroma Treatment:

A plantar fibroma can be treated conservatively or surgically.
