Your heel has been killing you every morning — that first step out of bed feels like stepping on broken glass. Your neighbor says it's plantar fasciitis. Your co-worker says it's a heel spur. Your internet search says both. Here's the honest answer: these two conditions are related but not the same thing, and understanding which one you have (or whether you have both) is the key to getting the right treatment.
Heel spurs and plantar fasciitis are the two most common culprits behind heel pain, and they're so often discussed together that patients — and even some online sources — use the terms interchangeably. They shouldn't be. One is a soft-tissue problem; the other is a structural change to the bone itself. The distinction matters because it shapes how the condition is diagnosed, how it should be treated, and what you can realistically expect for recovery.
The plantar fascia is a thick band of connective tissue that runs along the bottom of your foot, connecting your heel bone to the base of your toes. It acts like a bowstring, absorbing shock and supporting the arch with every step. When that tissue is overloaded — through too much time on your feet, a jump in training mileage, unsupportive footwear, or a change in activity — it can develop microscopic tears and become inflamed. That condition is plantar fasciitis.
It’s extremely common. Research published in NIH’s StatPearls estimates plantar fasciitis affects roughly 10% of the general population and accounts for about 1 million patient visits per year in the United States. It can strike at any age but peaks between 40 and 60, and it’s seen in active people and sedentary people alike — though runners tend to be at higher risk.
The hallmark symptom is sharp, stabbing pain at the inside bottom of the heel, worst with the first few steps in the morning or after sitting for a long stretch. After you’ve been moving for a few minutes, the fascia warms up and pain often eases — only to return after prolonged standing or activity.
A heel spur (medically called a calcaneal spur) is a calcium deposit that forms on the heel bone. Over months or years, repeated stress on the heel bone can trigger the body to lay down extra bone tissue at the attachment point of the plantar fascia. The result is a small, hook-like bony projection — visible on an X-ray — that points toward the arch.
Here’s the thing that surprises most patients: most heel spurs don’t cause pain on their own. The Cleveland Clinic estimates heel spurs affect about 15% of people, yet the majority of those individuals never feel a thing. Studies have found heel spurs in anywhere from 10% to 63% of people with no heel pain at all. Once formed, a heel spur is permanent — there is no non-surgical way to dissolve or shrink it.
The confusion is understandable because the two conditions share the same address. The plantar fascia attaches to the heel bone in roughly the same spot where heel spurs develop. When plantar fasciitis is present for a long time, the body’s repair response can gradually build up bone at that attachment, creating a spur. So a heel spur is often a consequence of chronic plantar fasciitis rather than a separate disease.
Research confirms this overlap: heel spurs appear in roughly 50% of patients with plantar fasciitis. But the reverse isn’t reliable — plenty of people with plantar fasciitis have no spur at all, and plenty with a spur have no pain. The bottom line is that the spur itself is rarely the pain generator; the inflamed and irritated plantar fascia is.
| Plantar Fasciitis | Heel Spur | |
|---|---|---|
| What it is | Inflammation of the plantar fascia (soft tissue) | Calcium deposit / bone growth on the heel bone |
| Pain pattern | Sharp stab at heel bottom; worst first steps AM, after rest | Often none; when present, aching with prolonged standing |
| Visible on X-ray? | No — soft tissue; may show up on ultrasound/MRI | Yes — bony projection clearly visible |
| How common? | ~10% of the population; 1M+ US visits/year | ~15% of people; majority are asymptomatic |
| Reversible? | Yes — ~75% resolve within 12 months with treatment | No — bone is permanent once formed |
| Main treatment target | Reduce fascia inflammation and load | Treat the soft-tissue cause; spur itself rarely needs surgery |
In clinic, the diagnosis starts with the story you tell: when the pain is worst, where exactly it hurts, what makes it better or worse, and how long you’ve had it. A physical exam then checks for tenderness at the medial heel (the classic plantar fasciitis spot) and assesses your foot mechanics and gait.
Imaging helps complete the picture:
The important takeaway: an X-ray showing a heel spur does not automatically explain your pain. Many patients arrive convinced the spur is the culprit, but after a thorough exam we find the fascia — not the bone — is the actual problem. Treatment plans that target the fascia tend to work; plans aimed solely at the spur usually don’t.
Our patients here in the Boise metro area tend to be active — hiking the Ridge to Rivers trails, training for Robie Creek or the Boise Marathon, gardening through the long high-desert summer. That active lifestyle is great, but it also means more load on the plantar fascia, especially when training ramps up in spring or when people switch from winter boots to flat sandals with no support. If you notice that tell-tale morning heel stab after a weekend of foothills hiking or a burst of yard work, don’t just push through it — that’s the fascia telling you something.
Because heel spurs are almost never the true source of pain, treatment for both conditions focuses on the plantar fascia. The good news is that the vast majority of cases respond to conservative care — no surgery required.
With this kind of consistent approach, research shows that roughly 75% of plantar fasciitis cases resolve within 12 months. Only a small minority (around 5–10%) ultimately need a procedure such as a plantar fascia release.

Not all heel pain is plantar fasciitis or a heel spur. See a podiatrist if:
Heel pain that arrives suddenly with a sharp pop or snap — especially during activity — and is followed by significant swelling and an inability to bear weight could indicate an Achilles tendon rupture or stress fracture, not plantar fasciitis. This warrants same-day or emergency evaluation. Similarly, heel pain accompanied by fever, skin warmth spreading up the leg, or an open wound needs immediate attention.
Yes — in fact it’s common. Research shows heel spurs appear in roughly 50% of people with plantar fasciitis, so the two often coexist. The plantar fasciitis is usually the source of the pain; the spur is a secondary finding.
A podiatrist uses your symptom history, a physical exam (checking exactly where the foot is tender), and imaging. X-rays can confirm a heel spur — it will show up as a bony projection off the heel. Ultrasound can reveal thickening or tearing of the plantar fascia. Often both findings are present together.
Usually not on its own. Because the spur itself is rarely the pain source, simply removing it without addressing the underlying soft-tissue problem does not always relieve symptoms. Surgery specifically for heel spurs is rarely performed. When heel surgery is needed, it typically focuses on releasing the tight plantar fascia.
With consistent conservative treatment — stretching, supportive footwear, activity modification, and sometimes injections or orthotics — roughly 75% of cases resolve within 12 months. Cases caught early and treated promptly often improve faster. A small percentage (5–10%) may ultimately need a procedure if conservative care doesn’t work.
Heel spurs and plantar fasciitis are related, often coexisting conditions — but they are not the same thing, and that distinction matters for treatment. Plantar fasciitis is the inflammation of soft tissue that causes your pain; a heel spur is a bony change that is usually a bystander, not the culprit. The good news is that both are very manageable: most people get lasting relief without surgery when they get an accurate diagnosis and stick with an evidence-based treatment plan.
