Why Are My Feet Swollen? Causes You Shouldn’t Ignore

Foot swelling is something nearly everyone experiences at some point. After a long day on your feet, a long flight, or standing in warm weather, mild swelling can feel almost expected. But when swelling becomes frequent, painful, or one-sided, it may be your body’s way of signaling a deeper issue.

Knowing the difference between normal swelling and a medical concern can help you protect your foot health—and your overall health.

What Causes Foot Swelling?

Foot swelling, also known as edema, occurs when excess fluid builds up in the tissues. This can happen for many reasons, some harmless and others more serious.

Common, Often Normal Causes

• Prolonged standing or walking

• Long flights or car rides

• Warm temperatures

• Temporary fluid retention

• Pregnancy

In these cases, swelling usually:

• Affects both feet

• Improves with elevation

• Resolves overnight or within a day

When Foot Swelling Is NOT Normal

Swelling becomes concerning when it’s persistent, painful, or associated with other symptoms. These cases deserve medical evaluation.

1. Swelling With Pain or Redness

Painful swelling may indicate:

• Injury or fracture

• Tendon or ligament damage

• Infection

Redness, warmth, or tenderness should never be ignored.

2. Swelling in One Foot Only

Swelling isolated to one foot or ankle can signal:

• A localized injury

• Infection

• Inflammatory conditions

• Circulation problems

Asymmetrical swelling is a key warning sign.

3. Swelling That Doesn’t Improve With Rest

If swelling persists despite elevation and rest, it may be related to:

• Venous insufficiency

• Lymphatic issues

• Arthritis

• Chronic inflammation

Long-term swelling can damage tissues if left untreated.

4. Swelling With Numbness or Tingling

Swelling that compresses nerves can cause:

• Numbness

• Tingling

• Burning sensations

This is especially important for patients with diabetes or nerve conditions.

5. Swelling With Skin Changes or Wounds

Swelling that causes:

• Shiny or tight skin

• Skin breakdown

• Slow-healing wounds

can increase infection risk and requires prompt care.

Medical Conditions Linked to Foot Swelling

Foot swelling may be associated with:

• Plantar fasciitis

• Posterior tibial tendon dysfunction

• Arthritis

• Gout

• Diabetes-related circulation issues

• Previous injuries

A podiatric evaluation helps identify the exact cause.

How Podiatrists Evaluate Foot Swelling

A podiatrist will assess:

• Swelling pattern and location

• Foot structure and alignment

• Circulation and nerve function

• Skin and nail health

• History of injuries or systemic conditions

Imaging or additional testing may be recommended when needed.

Treatment Options for Foot Swelling

Treatment depends on the underlying cause and may include:

• Compression therapy

• Supportive footwear or orthotics

• Activity modification

• Anti-inflammatory care

• Physical therapy

• Treatment of underlying conditions

Early treatment helps prevent complications and long-term damage.

When Should You See a Podiatrist?

You should schedule an appointment if foot swelling:

• Is painful or worsening

• Occurs in one foot only

• Doesn’t improve with rest

• Comes with redness, warmth, or skin changes

• Interferes with walking or daily activities

Swelling is not something to “push through.”

The Bottom Line

Mild foot swelling can be normal—but persistent, painful, or uneven swelling is not. Your feet play a vital role in mobility, circulation, and balance. Paying attention to changes and seeking early care can prevent serious complications and keep you moving comfortably.
