That first step out of bed can tell you a lot. If you wince as soon as your heel hits the floor, or you find the pain builds after a long day on your feet, it is reasonable to ask: why does my heel hurt?
Heel pain is one of the most common foot complaints, but it is not one single condition. The heel is a busy structure that absorbs load, helps propel you forward, and connects to tendons, fascia, joints and nerves. When something in that system is irritated, overloaded, inflamed or degenerative, the pain can feel surprisingly intense. The key is not just calming the pain down, but understanding what is actually driving it.
Why does my heel hurt in the morning, after walking, or at rest?
The timing of heel pain often offers useful clues. Pain that is worst with the first few steps in the morning is commonly linked with plantar fasciitis, where the thick band of tissue under the foot becomes irritated near its heel attachment. Pain that builds during or after activity may point to mechanical overload, tendon problems, joint irritation or a stress injury. Pain at rest, night pain, or pain associated with swelling, redness or heat can suggest something more concerning and should not be ignored.
Location matters as well. Pain under the heel is different from pain at the back of the heel. A sharp, stabbing sensation can mean something different from burning, tingling or aching. Two people may both say their heel hurts, yet the underlying cause and the right treatment can be quite different.
The most common causes of heel pain
Plantar fasciitis
This is the cause many people have heard of, and for good reason. Plantar fasciitis is one of the leading reasons for pain under the heel. It usually causes soreness where the plantar fascia attaches to the heel bone, often with marked pain on the first steps after rest.
Despite the name, it is not always a purely inflammatory problem. In longer-standing cases, the tissue may become more degenerative than inflamed. That is one reason quick fixes do not always work. You may feel some relief with rest, ice or supportive footwear, but if the mechanics causing overload are still present, symptoms can keep returning.
Heel spur
People are often told they have a heel spur after an X-ray, but a spur is not always the true cause of pain. Many people have a heel spur and no symptoms at all. A heel spur is more accurately thought of as a sign that the plantar fascia has been under traction over time, rather than proof of the pain source. Treating the X-ray finding instead of the actual condition can send people down the wrong path.
Achilles tendon insertion pain
If the pain is at the back of the heel rather than underneath it, the Achilles tendon may be involved. Insertional Achilles tendinopathy causes pain where the tendon attaches to the heel bone. It can be aggravated by walking uphill, climbing stairs, running, or shoes that press on the back of the heel.
This condition can be stubborn. Stretching that helps one tendon problem may aggravate another, especially if there is compression at the insertion point. That is why a specific diagnosis matters.
Retrocalcaneal bursitis and Haglund’s deformity
A bursa is a small cushioning sac near a joint or tendon. When the bursa between the Achilles tendon and heel bone becomes irritated, the result can be pain, swelling and tenderness at the back of the heel. Some patients also have a prominent bony contour on the heel, sometimes referred to as a Haglund’s deformity, which can increase friction in footwear.
This often affects people who wear rigid shoes, have a certain heel shape, or place repeated load through the area. It can overlap with Achilles problems, which again makes assessment important.
Fat pad syndrome
Not all heel pain comes from fascia or tendon. The natural fat pad beneath the heel acts like a shock absorber. If it thins, shifts or becomes bruised, standing on hard surfaces can feel as though you are walking directly on bone. The pain is often more central under the heel and may worsen with prolonged standing.
This is more common with age, repetitive impact, increased body weight, or after direct trauma.
Stress fracture
A stress fracture of the heel bone can cause deep, persistent pain, especially after a sudden increase in activity or load. Unlike plantar fasciitis, the pain may not ease once you have warmed up. It may become progressively worse and can be associated with swelling.
This is particularly relevant for active adults, people returning to exercise quickly, and anyone with reduced bone density. Continuing to push through this sort of pain can make things significantly worse.
Nerve-related heel pain
Burning, tingling, numbness or shooting pain can suggest nerve involvement. Entrapment of nerves around the heel or ankle, including tarsal tunnel syndrome in some cases, may mimic more common heel conditions. Nerve pain is often under-recognised because people expect all heel pain to be plantar fasciitis.
If the pain feels electrical, travels, or comes with altered sensation, that changes the investigation and treatment approach.
Why heel pain happens in the first place
Heel pain usually develops because the tissues are being asked to handle more than they can tolerate. Sometimes that overload is obvious, such as starting a new exercise program, increasing walking distances, changing footwear or spending long hours on hard floors. Sometimes it is more gradual.
Foot posture can play a role, but it is rarely as simple as saying a foot is too flat or too high arched. Calf tightness, limited ankle movement, body weight, work demands, training errors, arthritis, tendon weakness and previous injury can all contribute. In some patients there is also an underlying structural issue that keeps driving the problem despite sensible conservative treatment.
That is where specialist assessment becomes valuable. Rather than treating heel pain as a generic complaint, it helps to identify whether the pain is coming from soft tissue, bone, nerve, joint or a combination of factors.
When heel pain needs proper assessment
Many mild cases settle with early care, but there are clear situations where waiting too long is not helpful. If your heel pain has persisted for weeks, keeps returning, affects your walking, or stops you exercising or working comfortably, it deserves a proper diagnosis.
You should also seek assessment sooner if there is marked swelling, bruising, pain after injury, pain at night, signs of infection, numbness, or symptoms in the context of diabetes or inflammatory arthritis. Heel pain is often mechanical, but not always.
For persistent or complex cases, imaging may be useful. X-rays can show bony alignment, spurs, arthritic change or fracture. Ultrasound and MRI can provide more detail about fascia, tendons, bursae and other soft tissues. The right scan depends on the clinical question. More imaging is not automatically better – targeted imaging is.
What may help, and when conservative care is not enough
Treatment depends on the cause. For plantar fasciitis, this may include activity modification, supportive footwear, taping, orthotic management, calf and foot-specific rehabilitation, and careful load control. For Achilles-related pain, the exercise approach is different and footwear pressure becomes a bigger issue. A stress fracture requires protection and a different timeline altogether.
This is where generic internet advice can be misleading. Rolling your foot on a ball, stretching aggressively, or buying soft shoes may help one diagnosis and irritate another. Even cortisone, while useful in selected cases, is not appropriate for every type of heel pain and should be considered carefully.
When symptoms are prolonged or recurrent, it is worth asking why the problem is not resolving. Is the diagnosis correct? Is there a structural driver? Has treatment matched the tissue involved? Has enough attention been given to load, footwear, work demands and biomechanics? These are the questions that shape better outcomes.
In a smaller group of patients, surgery may be considered, but only after the diagnosis is clear and appropriate non-surgical care has been explored. Surgical options depend entirely on the underlying cause. A patient with chronic insertional Achilles pain, for example, needs a very different discussion from a patient with recalcitrant plantar fascia-related pain or a structural heel deformity. At Sydney Foot & Ankle Surgeon, that process starts with careful assessment and a clear explanation of what is causing the pain and what treatment pathway makes sense.
Why does my heel hurt if I have already tried treatment?
This is a common and fair question. Sometimes the original diagnosis was too broad. Sometimes the treatment was reasonable but incomplete. And sometimes there is an anatomical or degenerative issue that will not settle fully with temporary measures alone.
Persistent heel pain is frustrating because it interferes with ordinary life. It changes how you walk, what shoes you wear, whether you exercise, and how long you can stay on your feet. If you have reached the point where the pain is shaping your routine, it is time to stop guessing.
A helpful closing thought is this: heel pain is common, but ongoing heel pain should never be brushed off as something you just have to live with. The sooner the source is identified, the sooner treatment can be properly matched to the problem.
