Difference Between Plantar Fasciitis and Heel Spur

How to tell what is causing your heel pain and what to do next.

Plantar fasciitis and heel spurs are two of the most common findings in people with chronic heel pain. They are closely related, but they are not the same problem.

Plantar fasciitis is irritation and inflammation of the plantar fascia, the thick band of tissue that runs from your heel to your toes. Heel spurs are bony growths that can form on the heel bone over time, often in response to long-standing stress on the plantar fascia. Many people have heel spurs and never feel pain, while others have significant heel pain without a visible spur.

This guide explains the difference between plantar fasciitis and heel spurs, how they are diagnosed, and the treatment options that may help you get back to comfortable movement.

What is plantar fasciitis?

The plantar fascia is a strong, fibrous band that supports the arch of your foot and helps absorb shock when you walk. With repeated stress, the fascia can develop small tears and irritation where it attaches to the heel bone. This condition is known as plantar fasciitis and is one of the most common sources of heel pain.

Plantar fasciitis pain is often described as a sharp, stabbing pain at the bottom of the heel, especially with the first steps in the morning or after sitting. As you move around, the pain may improve, then return after prolonged standing, walking, or activity.

To learn more about how plantar fasciitis fits into the broader picture of heel pain, see our resources on heel pain treatments and the top causes of heel pain and when to seek help.

What is a heel spur?

A heel spur is a small bony outgrowth that can develop on the underside of the heel bone. It usually forms over time where the plantar fascia attaches, as the body responds to ongoing stress or pulling on that area.

Many heel spurs are found incidentally on X-rays in people who have no symptoms at all. In other words, a heel spur is not automatically the cause of your heel pain. In many cases, the pain you feel is from inflamed soft tissue (like plantar fasciitis) rather than the spur itself.

For a deeper look at how heel spurs and plantar fasciitis are related, the American Academy of Orthopaedic Surgeons provides a useful overview here: Plantar Fasciitis and Bone Spurs.

Plantar fasciitis vs heel spur: key differences at a glance

Symptoms: plantar fasciitis vs heel spur

Common symptoms of plantar fasciitis

• Sharp, stabbing pain at the bottom of the heel with first steps in the morning
• Pain that eases as you move, then returns with prolonged standing, walking, or running
• Tenderness where the heel and arch meet
• Tightness in the calf or Achilles tendon

Common findings with heel spurs

• Many people have a heel spur and no symptoms
• When painful, discomfort is often felt directly under the heel with pressure
• Pain can worsen over the course of the day with standing and walking

Because the symptoms can overlap, it is not always possible to tell on your own whether your pain is coming from plantar fasciitis, a heel spur, or both. A foot and ankle specialist can distinguish the source of your pain with a targeted exam and imaging when needed.

The Cleveland Clinic offers a helpful explanation of heel spur symptoms and causes here: Heel Spurs: Symptoms, Causes, and Treatment.

Causes and risk factors for both conditions

Many of the same factors that irritate the plantar fascia can also contribute to heel spur formation over time. These include:

• Repetitive high-impact activities such as running or jumping
• Standing or walking on hard surfaces for long periods
• Flat feet or very high arches
• Tight calf muscles or Achilles tendon
• Inadequate or worn-out footwear
• Increased body weight that adds stress to the heel

If you have flat feet or structural issues in the foot and ankle, you may be more likely to develop chronic heel pain. Overuse injuries and sports-related strain can also contribute. Learn more about how activity and sports can affect your feet in our guide on sports injuries and ankle pain.

Tightness and overuse in the Achilles tendon can also play a role in heel pain. If you are active or experiencing tightness in the back of the leg, our article on exercises to help prevent Achilles tendonitis and our page on ankle tendonitis treatment provide additional insight.

How plantar fasciitis and heel spurs are diagnosed

Diagnosis usually begins with a careful history and physical exam. Your provider may:

• Ask where and when your heel pain is worst
• Press on specific areas of the heel and arch to identify tenderness
• Assess your gait, foot structure, and calf/Achilles flexibility

Imaging such as X-rays may be ordered to check for heel spurs or other changes in the bone. However, the presence of a heel spur on X-ray does not always mean it is the cause of your pain. In many cases, treating plantar fasciitis and other soft tissue issues is enough to relieve symptoms, even if a spur is present.

When necessary, advanced imaging may be used to evaluate other causes of heel pain, such as stress fractures, nerve problems, or complex soft tissue injuries. If your heel pain is severe, persistent, or affecting your ability to work or stay active, a focused heel pain evaluation can help identify the right treatment path. You can explore options on our heel pain treatment page.

Treatment options: addressing the cause, not just the spur

Most people improve with conservative, non-surgical measures that focus on reducing inflammation, correcting biomechanics, and protecting the heel from further stress. Treatment plans are tailored to the cause of your pain rather than the X-ray alone.

Supportive footwear and inserts

Wearing shoes with good arch support, a cushioned yet stable heel, and adequate shock absorption is one of the most important steps you can take. For more detail, see our guide on how to choose the best shoes for heel pain.

Custom or over-the-counter inserts can also help redistribute pressure away from sensitive structures. In many cases, custom orthotics are recommended to correct underlying alignment issues and provide targeted support.

Stretching, activity modification, and strength

• Gentle stretching of the calf and plantar fascia
• Activity changes to reduce high-impact stress on the heel
• Strengthening exercises for the foot and ankle to improve support

If your pain is related to sports or repetitive strain, targeted rehab and training modifications may be recommended. Our sports injuries and ankle pain resources offer additional guidance.

Advanced therapies

When conservative care is not enough, advanced options may be considered as part of a comprehensive heel pain treatment plan. Depending on your condition, your provider may discuss therapies such as laser treatment for foot and ankle pain relief. You can also read more about how laser therapy may support pain management at our laser for pain information page.

Surgery to remove a heel spur is rarely the first choice and is typically reserved for cases that have not responded to extensive conservative treatment.

Can you tell at home if it is plantar fasciitis or a heel spur?

You may suspect plantar fasciitis if:

• Your pain is sharp and worst with the first steps in the morning
• The pain improves somewhat as you move, then returns with prolonged activity
• Tenderness is located where the heel and arch meet

You might suspect a symptomatic heel spur or deeper heel issue if:

• Pain is focused directly under the heel bone
• Discomfort builds through the day with standing and walking
• You have had long-standing heel pain with changes seen on imaging

However, self-diagnosis has limits, and many people have elements of both conditions. A proper exam is the most reliable way to understand what is driving your pain and which treatment options are most likely to help.

When to see a podiatrist for heel pain

You should consider seeing a foot and ankle specialist if:

• Heel pain lasts more than two weeks despite rest and supportive shoes
• Pain is severe enough to change how you walk or limit daily activities
• You notice swelling, warmth, or redness in the heel
• You have a history of diabetes, inflammatory arthritis, or prior foot surgery

If you are looking for care close to home, our podiatrists near me page can help you find a convenient location. When you are ready, you can book an appointment to discuss your heel pain, review imaging if needed, and build a treatment plan tailored to your goals.

Understanding the difference so you can take the next step

The key difference between plantar fasciitis and a heel spur is that one affects soft tissue while the other is a bony change. Both can be present at the same time, and both can contribute to heel pain. A careful evaluation helps clarify what is causing your symptoms so treatment can focus on the real source of the problem.

If you are unsure whether plantar fasciitis, a heel spur, or another issue is behind your heel pain, a focused visit with a foot and ankle specialist can provide clarity, a clear diagnosis, and a path forward.
