Heel Spur vs Plantar Fasciitis: Understanding the Key Differences

Heel pain is one of the most common foot problems we see in our offices—and two of the most frequent causes are heel spurs and plantar fasciitis. Because these conditions often occur together and produce similar symptoms, many patients assume they’re the same thing.

In reality, heel spurs and plantar fasciitis are two different conditions, even though they’re closely related. Understanding this distinction can help you recognize symptoms early and seek the right treatment before heel pain starts affecting your daily life.

Let’s take a closer look at what sets them apart.

What Are Heel Spurs and Plantar Fasciitis?

Although the terms are often used interchangeably, heel spurs and plantar fasciitis are not the same condition.

Heel Spurs

A heel spur is a small calcium deposit that forms on the underside of the heel bone (calcaneus). Over time, repeated stress and pulling on the foot’s connective tissues can lead to the development of this bony growth.

Heel spurs themselves rarely cause pain. In fact, many people have heel spurs and never know it until they appear on an X-ray.

Pain usually develops when the surrounding tissues—especially the plantar fascia—become irritated or inflamed.

Plantar Fasciitis

Plantar fasciitis, on the other hand, is inflammation of the plantar fascia, a thick band of connective tissue that runs along the bottom of your foot and supports the arch.

This condition occurs when the plantar fascia experiences repeated strain or tiny tears, leading to irritation and inflammation near its attachment at the heel.

Plantar fasciitis is one of the most common causes of heel pain. This is especially true among runners, as it accounts for almost 10% of all runner-related injuries and up to 15% of injuries amongst non-runners who spend long hours on their feet.

Why They’re Often Confused

Heel spurs frequently develop as a result of long-term plantar fascia strain, which means the two conditions often appear together. However, many people with plantar fasciitis do not have a heel spur, and many heel spurs don’t cause symptoms at all.

That’s why proper diagnosis by a foot and ankle specialist is so important.

How to Tell: Heel Spur vs Plantar Fasciitis

While symptoms may overlap, there are a few key differences in how these conditions typically present.

Pain Patterns

Plantar Fasciitis Symptoms

  • Sharp pain with the first steps in the morning
  • Pain improves after walking for a few minutes
  • Pain may return after long periods of standing or activity

Heel Spur Symptoms

  • More persistent or localized heel pain
  • Discomfort may continue even after the foot warms up
  • Pain may worsen with prolonged standing

Location of Pain

  • Plantar fasciitis: Usually felt along the bottom of the heel and arch
  • Heel spur: Pain is often concentrated at a specific point under the heel

What Are Common Heel Pain Causes?

Both heel spurs and plantar fasciitis usually develop from repeated strain on the foot, particularly where the plantar fascia attaches to the heel bone.

Common factors that contribute to these conditions include:

  • Flat feet or high arches
  • Tight calf muscles or Achilles tendon
  • Running or high-impact sports
  • Standing or walking for long periods
  • Wearing unsupportive footwear
  • Excess weight or sudden weight gain

Because many of these risk factors overlap, plantar fasciitis and heel spurs often develop together or influence one another over time.

What Are the Treatment Options for Each Condition?

The good news is that most heel pain improves with conservative treatment when addressed early.

Conservative Treatments

Many patients experience relief with non-surgical therapies such as:

  • Custom orthotics or arch supports
  • Stretching exercises for the plantar fascia and calf muscles
  • Physical therapy
  • Supportive footwear
  • Anti-inflammatory treatments
  • Night splints
  • Activity modification

Advanced Non-Surgical Treatments

If symptoms persist, advanced therapies may help stimulate healing, including:

  • Regenerative medicine treatments
  • Shockwave therapy
  • Image-guided injections

These options can often accelerate healing without surgery.

When Surgery Is Considered

Surgery is rarely needed but may be recommended when:

  • Pain persists after several months of treatment
  • Structural problems are contributing to the condition
  • Conservative care fails to provide relief

Our board-certified foot and ankle specialists can determine whether surgical treatment is appropriate.

When Should You See a Podiatrist for Heel Pain Relief?

Heel pain can be frustrating, especially when it starts interfering with your daily routine. While heel spurs and plantar fasciitis are often confused, they’re distinct conditions that require an accurate diagnosis to be treated effectively.

If your heel pain isn’t improving with rest or basic at-home care, it may be time to request an appointment with one of our specialists. At the Foot & Ankle Center of Arizona, our team focuses on identifying the underlying cause of heel pain and creating a personalized treatment plan designed to help you move comfortably again.
