Heel Spur on an X-Ray: Is It the Cause of Heel Pain?

A heel spur on an X-ray is a small bony growth on the underside of the heel bone, where the plantar fascia attaches. It is a common finding, and most people with a heel spur do not feel pain from it. When heel pain is present, it usually comes from plantar fasciitis rather than the spur itself.

Cleveland Clinic describes the spur as the body's response to repeated stress on the plantar fascia, the thick band of tissue that runs from the heel to the ball of the foot. Over time, extra bone can build up at the attachment point. The American Academy of Orthopaedic Surgeons (OrthoInfo) states plainly that heel spurs do not cause plantar fasciitis pain.

This guide is for adults whose X-ray report mentions a heel spur, often called a calcaneal or plantar spur. It explains the finding and helps you prepare questions. It cannot diagnose the cause of your heel pain.

Most heel pain is not an emergency. Healthdirect advises seeking medical help straight away for a sudden pain or popping feeling in the heel or calf during exercise, which can be a ruptured Achilles tendon. Heel pain with a fever, or with significant redness or swelling, also needs prompt care.

The NHS advises seeing a GP if any of the following apply. Heel pain after an injury should also be checked, because an X-ray mentioning a spur does not rule out other problems.

• Pain that is severe or stops you doing normal activities.
• Pain that is getting worse or keeps coming back.
• No improvement after 2 weeks of self-care.
• Tingling or numbness in the foot.
• Foot pain if you have diabetes, as foot problems can be more serious.

They are related but not the same thing. Plantar fasciitis is strain or irritation of the plantar fascia. A heel spur is extra bone that may form where that tissue pulls on the heel. One describes soft tissue, the other a bony change seen on an X-ray.

Cleveland Clinic notes that heel pain blamed on heel spurs is usually caused by plantar fasciitis. That is why two people with similar-looking spurs can feel very different: one has no symptoms, while the other has a painful, irritated fascia.

Plantar fasciitis has a typical pattern. The NHS describes pain on the bottom of the foot around the heel and arch that is often worst with the first steps after sleep or rest, eases once moving, then returns after long periods of standing or walking.

Yes. Cleveland Clinic estimates that heel spurs affect about 15% of people, and says most people with one do not feel pain from it. OrthoInfo also states that most people who have heel spurs do not have heel pain.

So a spur seen on an X-ray taken for another reason is often an incidental finding. If you do have heel pain, the spur may simply be a sign that the area has been under strain for a long time. Its presence does not mean the pain will last longer or need surgery.

The NHS lists factors that raise the chance of plantar fasciitis, including being aged 40 to 60, starting exercise on hard surfaces, tight calves, long periods of standing and poorly cushioned shoes. These are often more useful to discuss than the spur itself.

Heel pain is often assessed by examination and history alone. OrthoInfo explains that X-rays are mainly used to rule out other causes of heel pain, such as a fracture or arthritis. MRI and ultrasound are rarely needed, usually only when another problem is suspected.

Heel pain has other possible causes. Healthdirect lists Achilles tendon problems, heel bursitis, fat pad problems, stress fractures, nerve entrapment such as tarsal tunnel syndrome, and arthritis. Read the whole report, not only the line about the spur, and ask what else was looked for.

Treatment targets the soft tissue, not the bone. Cleveland Clinic says heel spurs are treated the same way as plantar fasciitis. OrthoInfo describes calf and plantar fascia stretching as among the most effective ways to relieve the pain.

OrthoInfo reports that more than 90% of people with plantar fasciitis improve within 10 months of starting simple treatment. Surgery is generally considered only after long periods of non-surgical care have not helped, and Cleveland Clinic notes that surgery to remove heel spurs is rarely performed. Discuss pain relief medicines or injections with a clinician or pharmacist.

• Stretching the calf muscles and the sole of the foot, as shown by a clinician or physiotherapist.
• Cushioned, supportive shoes, and heel pads or insoles where advised.
• Resting the foot, reducing long periods of standing or high-impact activity, and using ice wrapped in a towel.
• Losing weight if overweight, which the NHS notes can ease strain on the foot.
• A physiotherapist or podiatrist for exercises, insoles or night splints if self-care is not enough.

Bring the X-ray report and a short note of when the pain started, when it is worst and what you have tried.

• Is the heel spur likely to be related to my pain, or is it an incidental finding?
• Does my examination suggest plantar fasciitis, or another cause such as an Achilles problem or nerve irritation?
• Did the X-ray show anything else, such as a fracture or arthritis?
• Which stretches and footwear changes should I try, and for how long before reviewing?
• Would a physiotherapist or podiatrist referral help me?
• What symptoms should make me come back sooner?

On SameCase, patients and verified doctors share de-identified cases. Reading how others with a heel spur on their X-ray described their pain pattern, tests and treatment conversations can help you decide what details to record and which questions to bring.

Similar cases cannot show what is causing your heel pain or which treatment will work for you. Use them to prepare, and let the clinician who examines your foot guide the decisions.
