Why Is There a Bump on My Foot? Common Causes and When to Get It Checked

You are getting dressed one morning and notice something new. Maybe it is a bump on the side of your foot. Maybe it feels like a lump on the top of your foot that was not there before.

Your first thought is usually the same:

“Should I be worried about this?”

The answer depends on what is causing it.

Some foot growths are harmless and simply need monitoring. Others can become painful, affect the way you walk, or signal an underlying condition that should be evaluated by a podiatrist.

At Advanced Foot & Ankle Specialists in Sugar Land, TX, one of the most common questions we hear is, “What is this growth on my foot?” Fortunately, most causes can be diagnosed quickly and treated effectively once we understand what is going on.

Symptoms That May Accompany a Foot Growth

Not every bump causes pain right away.

Some patients notice only a visible change while others experience symptoms such as:

• Pain when walking
• Tenderness when touched
• Swelling
• Redness
• Difficulty wearing shoes
• Burning sensations
• Tingling or numbness
• Joint stiffness
• A growth that seems to be getting larger

The location of the growth often provides important clues about the underlying cause.

Common Causes of a Bump on the Foot

Several different conditions can create a noticeable bump on the foot.

Bunions

One of the most common causes is a bunion.

A bunion develops when the big toe gradually shifts toward the smaller toes, causing the joint to stick outward.

Many patients first notice a small bump near the big toe that slowly becomes more prominent over time.

Common symptoms include:

• Pain around the joint
• Swelling
• Difficulty wearing certain shoes
• Redness around the bump

Bunions rarely improve without treatment and often worsen gradually over the years.

Ganglion Cysts

A ganglion cyst is a fluid-filled sac that forms near a joint or tendon.

Patients often describe finding a soft lump on the top of the foot that seems to appear suddenly.

These cysts may:

• Change in size
• Cause pressure from shoes
• Create discomfort during activity
• Irritate nearby nerves

While usually benign, they can become bothersome depending on their location.

Bone Spurs

Bone spurs are extra growths of bone that develop due to arthritis, repetitive stress, or chronic inflammation.

Many people notice a hard bump on the top of the foot or near a joint.

Bone spurs may become painful when they rub against shoes or surrounding soft tissue.

Arthritis

Arthritis can cause joints to enlarge and become more noticeable over time.

Patients frequently describe discovering a lump near a joint that feels hard and gradually increases in size.

Arthritis-related changes commonly affect:

• The big toe joint
• Midfoot joints
• Ankle joints

Morning stiffness and pain are often present as well.

Plantar Fibromas

A plantar fibroma is a firm growth that develops within the plantar fascia, the thick tissue along the bottom of the foot.

Unlike many other foot conditions, this type of lump usually develops in the arch.

Patients often report:

• A firm lump beneath the foot
• Pain when standing
• Discomfort while walking barefoot

Neuromas

A neuroma is a thickening of nerve tissue, most commonly found between the toes.

Patients frequently describe it as feeling like they are walking on a pebble or standing on a small lump inside the foot.

Symptoms often include:

• Burning pain
• Tingling
• Numbness
• A sensation that something is stuck in the shoe

Gout

Gout can sometimes create hard deposits around joints called tophi.

These growths often appear near the big toe joint and may feel like firm lumps beneath the skin.

Gout is typically accompanied by episodes of severe pain, redness, swelling, and warmth.

When Should You Get a Foot Lump Checked?

Many people wait months or even years before having a growth evaluated.

The reality is that you do not need to wait until it becomes severe.

You should schedule an evaluation if:

• The lump is getting larger
• It causes pain
• Walking becomes uncomfortable
• You notice redness or swelling
• It interferes with footwear
• You experience numbness or tingling
• You do not know what is causing it

A professional diagnosis can provide peace of mind and help prevent the problem from worsening.

What Happens If You Ignore It?

Not every foot bump is dangerous, but some conditions become more difficult to treat when left alone.

Depending on the cause, delaying treatment can lead to:

• Increased pain
• Joint damage
• Nerve irritation
• Difficulty walking
• Progressive deformity
• Reduced mobility

This is particularly true for bunions, arthritis, and certain nerve-related conditions.

Early treatment often means more conservative options and better outcomes.

How a Podiatrist Diagnoses Foot Bumps

Many foot conditions look similar from the outside.

A bump caused by a bunion can appear very different from a ganglion cyst, arthritis-related enlargement, or a soft tissue mass.

At our Sugar Land office, diagnosis may include:

• Physical examination
• Review of symptoms
• Digital X-rays
• Diagnostic imaging when necessary
• Gait and biomechanics evaluation

The goal is to determine exactly what is causing the growth before recommending treatment.

Treatment Options

Treatment depends entirely on the diagnosis.

Custom Orthotics

Orthotics can help relieve pressure and improve foot mechanics when structural issues contribute to pain.

Footwear Changes

In many cases, supportive footwear can reduce irritation and prevent symptoms from worsening.

Anti-Inflammatory Treatment

Reducing inflammation can improve comfort for patients with arthritis, bunions, and other joint-related conditions.

Cyst Treatment

Ganglion cysts may be monitored, drained, or removed depending on symptoms and recurrence.

Surgical Treatment

When conservative options no longer provide relief, surgery may be recommended to correct the underlying problem and restore function.

FAQs

What causes a lump on the side of the foot?

A lump on the side of the foot may be caused by a bunion, ganglion cyst, arthritis-related joint changes, soft tissue growth, or other structural conditions.

Should I worry about a bump on my foot?

Not every bump is serious, but any growth that becomes painful, enlarges, or affects your ability to walk should be evaluated by a podiatrist.

Why does it feel like I am walking on a lump?

This sensation is commonly associated with neuromas, plantar fibromas, or other soft tissue conditions affecting the bottom of the foot.

Can arthritis cause bumps on the foot?

Yes. Arthritis can enlarge joints and contribute to bone spur formation, both of which may appear as noticeable bumps.

Will a foot lump go away on its own?

Some cysts may fluctuate in size, but many causes of foot lumps do not resolve without treatment. A professional evaluation can determine the best course of action.
