Heel Spurs: Why the Spur Usually Isn't the Pain
The X-ray comes back and there it is: a small hook of bone under the heel, pointing forward. It looks like something that would hurt, and the natural question is whether someone can take it out.
Most of the time nobody should, because the spur is not what hurts. A large share of adults with a spur on X-ray have no heel pain at all, and in the men who do have pain, it comes from the soft tissue next to the spur, not the bone. That one fact changes the plan: you treat the tissue, the spur stays where it is, and the heel gets better anyway.
This guide covers what the spur is, why it is a marker rather than a cause, and what treatment looks like under the heel and behind it.
What a heel spur is
Where it sits. A heel spur, or calcaneal spur, is a shelf of extra bone on the heel bone. The common one sits on the underside, where the plantar fascia attaches, and points forward toward the toes. The other one sits on the back of the heel, where the Achilles tendon attaches, and often comes with a thickened tendon and a bump you can feel through the skin.
How it forms. Where a strong band of tissue pulls on bone for years, the attachment is repeatedly stressed and repaired, and the repair lays down more bone along the line of pull. Some researchers think vertical compression of the heel matters more than pull, because the spur tracks so closely with weight and age. Either way, a spur is a record of load applied over years. It takes years to form and does not go away on its own.
Who has one. Depending on the group X-rayed, roughly one adult in eight to one in three has a plantar spur, and the rate climbs with age: in one series of older adults, more than half had one. Body weight and diabetes both raise the odds.
The fact that decides the article
The X-ray. One study compared heel X-rays of people with plantar fasciitis against people with no heel complaint. Spurs showed up in about 85% of the first group and about 46% of the second, so close to half of the people with no heel pain had one. What separated the groups was not the bone but the soft tissue: a thickened fascia and a changed fat pad.
What that means. The spur is more common in men with plantar heel pain, but it is a marker of the load the heel has carried, not the source of the pain. Plenty of men have a spur and feel nothing; plenty with textbook plantar fasciitis have a clean X-ray. The American Academy of Orthopaedic Surgeons puts it plainly: most people with a heel spur do not have heel pain, and the spur does not cause plantar fasciitis pain.
Where the pain comes from. Under the heel, the pain is the fascia: irritated and micro-torn at its attachment, worst on the first steps of the morning and after sitting. That is plantar fasciitis. Behind the heel, the pain is the Achilles insertion, where the tendon fibers meet bone, and the small fluid-filled bursa between tendon and bone that gets pinched by the bump and by a stiff shoe. In both places, the tissue that hurts is the tissue you treat.
Why nobody cuts the spur out
It doesn't reliably fix the pain. If the spur were the cause, removing it would cure the problem. It doesn't. Orthopedic guidance is that plantar fasciitis can be treated without removing the spur, and that even in surgery the spur is usually left alone because removing it doesn't change the result.
It adds risk. Heel surgery means an incision, weeks of protected walking, and complications: nerve injury, a flattened arch if too much fascia is released, a heel bone fracture, and a long recovery. Taking that on for a piece of bone that wasn't hurting is a bad trade.
What surgery targets instead. When surgery does happen, it is aimed at the tissue: a partial release of the fascia at its attachment, or a lengthening of a tight calf that stretching hasn't freed. Both are reserved for men who have done a year of proper nonsurgical care without improvement, because more than nine in ten recover without an operation.
Treating the pain under the heel
The treatment for a plantar spur is the treatment for plantar fasciitis. The full protocols live in the morning heel pain guide and the plantar fasciitis exercises guide; this is the shape of it.
Stretching. Calf and fascia, daily, for weeks. First-line in every guideline and the step that does most of the work. A calf shortened by decades of sitting keeps the fascia pre-loaded.
Load management. Cut the volume that flared it, without stopping altogether.
Heel cups and shoe stiffness. A cushioned heel cup spreads impact across the heel pad. A firm midsole that doesn't fold in the middle stops the fascia being stretched with every step.
Strengthening. Once the sharp pain eases, loading the foot and calf builds tissue that tolerates work.
Weight. One of the strongest predictors of both the spur and the pain. Even modest loss reduces the load on the fascia with every step.
Night splint. Holds the foot at working length overnight so the first steps aren't stretching a cold, shortened fascia. Worth adding when the morning spike hasn't eased after a few weeks of stretching.
Time. Months, not weeks. Most men are much improved inside three months; a fair share need longer. The spur will still be on the X-ray when the pain is gone, which is the whole point.
The spur behind the heel: its own rules
A spur at the Achilles attachment, often alongside a bony bump called Haglund's deformity, follows different rules because the problem is pressure and tendon load, not fascia tension. The Achilles pain guide has the full protocol.
Avoid a hard heel counter. The stiff back of a dress shoe or work boot rubs directly on the bump and the bursa. Foot and ankle surgeons name men's dress shoes specifically. Softer or open-backed shoes come first.
Use a heel lift. A small lift inside the shoe reduces the pull of the tendon on its attachment and moves the bump away from the heel counter.
Eccentric calf work, with limits. Slow lowering exercises are standard for Achilles problems. For the insertion, though, the heel should lower only to floor level, not below the edge of a step. The deep drop used for mid-tendon pain pinches the insertion against the bone edge and can make it worse.
No steroid injection into the tendon. Injections around the Achilles raise the risk of rupture, and family medicine guidance is to avoid them.
Injections, shockwave, and surgery
Corticosteroid injection. For plantar fasciitis, one injection can buy short-term relief, but repeated shots weaken the fascia and can lead to a rupture. A podiatrist may offer it once for a reason, not as a plan.
Shockwave therapy. Sound-wave pulses applied to the attachment to provoke healing. Trial results are mixed, but the risk is low, so it is often tried in stubborn cases before anyone talks about surgery.
Surgery. A conversation when a year of proper care has failed, not a first move, and not a spur removal. For the posterior spur, surgery may remove the bump and clean up the tendon, again only after nonsurgical care has had a real chance.
What to do this week
- Stop treating the spur. Decide whether the pain is under the heel or behind it; the plans differ.
- Start the stretch protocol. The three morning moves, before the first step and after any long stretch of sitting, every day.
- Fix the shoe. Under the heel: a cushioned heel cup and a sole that doesn't fold. Behind: a soft or open heel counter and a small heel lift in both shoes.
- Cut the load that flared it, not to zero. Fewer miles, fewer hours on concrete.
- Book the visit if nothing moves in six weeks, or sooner if any red flag below applies. The doctor-prep checklist keeps the appointment on the pain, not the X-ray.
When it's not a wait-and-see
Same-week appointment, not a routine one, if any of these apply:
- Heel pain with a fever, or a heel that is hot, red, and swollen.
- Pain that started with a fall, a jump landing, or a sudden pop behind the heel.
- A heel that hurts at rest and at night, not only when you load it.
- Numbness, tingling, or burning under the heel or along the arch.
- You have diabetes and any break in the skin of the heel, however small. The diabetic foot care guide explains why.
Bottom line
A heel spur is a record of years of load on the heel, not the thing that hurts. A large share of adults with no heel pain have one, the men who do have pain hurt because of the fascia or the Achilles insertion next to it, and cutting the spur out doesn't reliably fix anything. Treat the tissue, and the spur will still be on the next X-ray when the pain is gone.
Start with the fascia side, which is by far the more common: the plantar fasciitis exercises guide has the routine.
