8 Causes of Heel Pain and How to Tell Them Apart by Location

Understanding Heel Pain Causes

Every step you take sends 1.2 to 1.5 times your body weight straight into the heel. Run, and that load jumps to two or three times body weight on each strike. At an average of 6,000 to 10,000 steps a day, the heel absorbs thousands of these impacts before you even get to the evening. Because the plantar fascia, the Achilles tendon, the heel's fat pad, and the calcaneus itself all have to withstand this repeated pounding, a breakdown in any single one of them shows up almost immediately as pain.

The plantar fascia works like a bowstring under the arch. As you push off, the toes extend and the fascia tightens through what is known as the windlass mechanism, converting the foot into a rigid lever for propulsion. That tightening concentrates enormous tensile force right where the fascia inserts into the heel bone. That insertion point also happens to sit in a watershed zone with comparatively poor blood supply, which is a large part of why microtears there heal more slowly than similar injuries elsewhere in the body, and why heel pain has a habit of turning chronic if it is not addressed early.

Foot and ankle specialty groups estimate that roughly one in ten adults will experience some form of heel pain, plantar fasciitis included, at least once in their lifetime. The rate climbs noticeably in people in their 40s through 60s, in long-distance runners, and in anyone whose job keeps them on their feet all day. Because the location and pattern of the pain differ depending on which structure is involved, figuring out the specific cause is the real first step toward getting better, not just resting and hoping it fades.

What this guide covers

Below, we walk through eight distinct causes of heel pain grouped by where the pain shows up, how to use the pattern of your symptoms to narrow things down, the red flags that mean you should stop self-treating and see a specialist, and a phase-by-phase protocol for managing the pain once you have a reasonable idea what is driving it.

Eight Causes of Heel Pain, Sorted by Location

Where the pain sits, sole of the foot versus the back of the heel, and which tissue is involved, soft tissue versus bone, split these eight causes into fairly distinct groups. See also: Morning Plantar Fasciitis Pain: Causes and Management

Pain under the sole

• Plantar fasciitis: the single most common cause of heel pain. Repeated microdamage and degenerative change accumulate where the plantar fascia attaches to the calcaneus. A case-control study by Riddle and colleagues, published in the Journal of Bone and Joint Surgery, identified a higher body mass index, limited ankle dorsiflexion (a smaller angle when you lift the top of your foot toward the shin), and prolonged standing at work as independent risk factors. In practice, the combination of stiff calves and a desk-to-standing-job schedule is the pattern we see most often.
• Fat pad atrophy: a cushioning pad of fibrous fat sits directly under the heel bone to absorb impact. With age, or after years of accumulated pounding, that pad thins out. It becomes more noticeable after 40, especially in people who spend a lot of time barefoot on hard floors, since the pad simply has less material left to spread the load.
• Nerve entrapment (including Baxter's nerve): the first branch of the lateral plantar nerve runs along the inside of the heel, and compression there produces pain with tingling or a burning quality layered on top. It gets misdiagnosed as plantar fasciitis often enough that it is worth mentioning on its own; the giveaway is usually that burning, electrical quality rather than a dull ache.
• Calcaneal stress fracture: shows up characteristically in runners who ramped up mileage too quickly, or in military recruits during basic training. Squeezing the heel from both sides (a side-to-side compression test) reproduces the pain, a useful way to distinguish it from soft-tissue causes before imaging confirms it.

Pain at the back or top of the heel

• Achilles tendinopathy: cumulative overuse damage to the tendon connecting the calf muscles to the heel bone. It splits into a mid-portion form and an insertional form near the heel attachment, and the two respond somewhat differently to rehab; mid-portion tendinopathy tolerates loaded stretching better, while insertional cases often need the ankle kept closer to neutral during exercises.
• Haglund's deformity: a bony prominence at the back of the heel rubs against the heel counter of a shoe, triggering bursitis and pain. Stiff, structured heel counters make it worse; this is the classic pump-bump seen with certain dress shoes and ice skates.
• Sever's disease (calcaneal apophysitis): repetitive traction stress on the growth plate of the heel bone in growing children and adolescents. It shows up disproportionately in young athletes doing a lot of running and jumping, soccer and basketball players especially, and tends to resolve once growth is complete.

Bone and systemic causes

• Heel spurs: a bony outgrowth that forms from chronic traction on the plantar fascia. Multiple studies agree that spurs found on X-ray do not correlate well with how much pain a person actually has; plenty of pain-free people have them, and plenty of people with severe pain do not.
• Systemic inflammatory disease: conditions like ankylosing spondylitis or reactive arthritis can cause enthesitis, inflammation where a tendon attaches to bone, in both heels at once. When that is the pattern, it is worth looking at the whole picture rather than treating it as a purely local mechanical problem.

A common mistake worth naming

The most frequent error we see is treating every case of sole pain as plantar fasciitis and applying the same stretching routine regardless of what is actually going on. If pain does not ease at all after two to three weeks of a plantar-fascia-specific routine, that is a signal to reconsider the diagnosis rather than simply stretching harder.

Reading Your Symptoms to Narrow Down the Cause

An accurate diagnosis is a job for a specialist, but paying attention to when and how the pain shows up can narrow the list considerably before you ever get to a clinic.

First-step pain in the morning

• A sharp jab with the very first steps out of bed that eases after a few dozen steps is the classic presentation of plantar fasciitis.
• The mechanism is straightforward: the fascia shortens slightly while you sleep, and putting weight on it suddenly re-stretches those partially healed microtears, hence the jolt.

Pain that builds with activity

• If pain is worst after exercise or toward the end of a long day on your feet, fat pad atrophy or a calcaneal stress fracture become more likely candidates.
• A pulling sensation at the back of the heel when climbing stairs or rising onto your toes points more toward Achilles tendinopathy.

Tingling or burning alongside the pain

• Pain accompanied by tingling or a burning sensation along the inside of the sole suggests nerve entrapment.
• Pain that continues at night and does not ease much with rest raises the likelihood of either a neurological or an inflammatory cause.

A quick self-check

If three or more of the following apply to you, it is worth booking a consult. Further reading: Achilles Tendon Care: Causes of Heel Pain and Rehab Exercises

1. Heel pain that has lasted more than two weeks
2. Repeated sharp pain with the first steps after waking
3. Pain that clearly worsens after running or jumping
4. Swelling or warmth around the heel
5. Tingling or a burning sensation radiating through the sole
6. Both heels hurting at the same time
7. Reaching for pain medication three or more times a week

When to See an Orthopedic or Foot Specialist

Most heel pain improves with conservative care, but certain signals mean it is time to stop self-managing and get it looked at.

Go in right away if

• Severe pain right after trauma: a fall from height or a hard impact that leaves you unable to bear weight at all.
• Rapid swelling or visible deformity: the shape of the heel noticeably changes or swells dramatically.
• High fever alongside redness: a temperature above 38.5°C (101.3°F) with a red, swollen heel needs to rule out a joint infection or cellulitis.

Book an appointment within two to four weeks if

• Four or more weeks of stretching and rest at home have not moved the needle.
• The whole heel hurts after a jump in running volume, and side compression reproduces the pain, raising suspicion of a stress fracture.
• Tingling or burning is new, or is getting worse over time.
• Both heels hurt at once along with morning joint stiffness, a pattern that points toward an inflammatory cause rather than a purely mechanical one.

A few additional signals are worth flagging even though they are easy to overlook: unexplained weight loss alongside the heel pain, pain that specifically wakes you at night rather than simply being present, and any numbness spreading beyond the sole into the toes or ankle. None of these are common, but any one of them changes the urgency of getting evaluated.

How the diagnosis actually gets made

A clinic will typically use some combination of the following to sort out the cause. See also: Ankle Pain After Walking Long Distances

• Physical exam: tenderness on palpation of the plantar fascia, ankle dorsiflexion angle, the side-compression test, and a basic neurological check.
• Ultrasound: shows in real time whether the plantar fascia or Achilles tendon has thickened or partially torn.
• X-ray: picks up bone spurs, stress fractures, and alignment problems.
• MRI: reserved for cases ultrasound and X-ray cannot sort out; it gives a detailed look at soft tissue and any bone marrow edema.
• Blood tests: ordered when pain is bilateral or accompanied by systemic symptoms, checking inflammatory markers (CRP, ESR) and sometimes HLA-B27.

A Phase-by-Phase Management Protocol

The specifics shift depending on the underlying cause, but a shared staged approach works across most of them.

Acute phase (onset to about 1 week)

• Activity modification: pause running, jumping, or anything that clearly triggers the pain, but do not go to full bed rest; keep walking within a pain-free range.
• Ice: 15 minutes, two to three times a day, to calm the inflammatory response.
• Taping or an insole: fascia-support taping or a heel-cup insole redistributes load away from the injured tissue.

Subacute phase (roughly weeks 1 through 6)

• Progressive stretching: plantar fascia and calf (gastrocnemius and soleus) stretches, two to three sessions a day.
• Night splints: for plantar fasciitis specifically, a splint that keeps the ankle at a neutral angle overnight has been reported to ease that first-step pain in the morning.
• Near-infrared wellness care: a warming sensation paired with support for local circulation makes this a reasonable addition before and after stretching sessions.

A rough benchmark for moving from subacute care into the chronic-phase program below: morning first-step pain has dropped to a mild twinge rather than a sharp jab, and you can walk 20 to 30 minutes without the pain climbing above a 3 out of 10. If pain is still sharp and unchanged after four full weeks of consistent subacute care, that is the point to loop back to a specialist rather than pushing further on your own.

Chronic phase (beyond 6 weeks)

• Eccentric loading: for Achilles tendinopathy, eccentric calf work off a step or stair is the standard rehab exercise.
• Shockwave therapy (ESWT): a physiotherapy option a specialist may consider for chronic plantar fasciitis or Achilles tendinopathy that has persisted beyond six months.
• Reassess weight and footwear: shedding excess weight and switching to shoes with adequate cushioning helps prevent the whole cycle from restarting.

Mistakes that stall recovery

Two mistakes show up again and again. The first is stopping the stretching routine the moment the sharp pain fades; the underlying stiffness and the tissue's reduced tolerance for load are still there, and the pain simply comes back within a few weeks. The second is jumping straight back to full running volume once walking feels fine, skipping the gradual return that the tissue actually needs. A better rule of thumb: once you are pain-free during daily walking, add running back at no more than 10% of your previous weekly distance, and hold that level for a full week before increasing again.

Signals to stop and dial back

Stop the current phase of exercise and ice again if pain climbs above 5 out of 10 during activity, if swelling returns after a day that had been swelling-free, or if a new burning or tingling sensation appears that was not there before; these usually mean you progressed a stage too early.

Calf and Plantar Fascia Stretching Routine

Stretching and strengthening make up the best-supported piece of heel pain management, by a wide margin.

Plantar fascia stretches (3 to 4 times daily)

1. Towel stretch: sitting down, loop a towel around the ball of the foot and pull toward you until you feel a pull along the sole. Hold 20 to 30 seconds, repeat three times.
2. Big toe stretch: grab the big toe and pull it back gently until the plantar fascia feels stretched. Hold 15 to 20 seconds.
3. Golf ball rolling: roll a golf ball or a water bottle under the sole, back and forth, with gentle pressure for one to two minutes.

Calf (Achilles) stretches

1. Wall stretch, straight knee: hands on a wall, one leg extended behind you with the heel flat on the floor. Hold 30 seconds, three sets each side.
2. Wall stretch, bent knee: same position with the back knee slightly bent, shifting the stretch onto the soleus rather than the gastrocnemius.

Eccentric calf strengthening (for Achilles rehab)

1. Stand with the balls of your feet on a stair edge, rise up on both heels (concentric), then shift weight to the unaffected side and lower slowly on the affected side alone (eccentric).
2. 15 reps by 3 sets, twice a day, done once with the knee straight and once with it slightly bent.
3. This protocol has been studied for 12 weeks or longer, with meaningful pain reduction reported over that timeframe. It is not a routine that pays off in a week or two, and expecting a fast result is the most common reason people abandon it early.

How to know you are doing too much

• Keep pain at or below 3 out of 10 during the exercise itself.
• If pain is still elevated the morning after, that is the signal to scale back, not push through.
• If a stress fracture is suspected, rest and a specialist visit take priority over any stretching program.

Using Near-Infrared Wellness Care

Near-infrared light, roughly in the 800 to 880nm range, penetrates the skin and underlying tissue and is used as a supportive tool in sports recovery and general wellness. A review of photobiomodulation by Hamblin (2018, AIMS Biophysics) describes near-infrared light being absorbed by cytochrome C oxidase in mitochondria, with downstream effects on the ATP production pathway, and involvement in local blood flow and tissue metabolism. It is worth being direct about the limits of that evidence: most of it comes from cellular and animal studies, and none of it amounts to a claim that the light treats or cures any specific condition.

Tips for the heel and calf

• Used for 5 to 10 minutes before stretching, it works reasonably well as a warm-up to loosen calf and heel tissue before the routine above.
• After activity, a 10 to 15 minute session held 5 to 10cm from the skin fits naturally into a conditioning routine.
• During a period of acute swelling and heat, ice comes first; once that subsides in the subacute phase, warming-based care like this can be layered in alongside it.
• If pain or tingling is severe or persistent, seeing a specialist should take priority over continuing self-care at home.

A note on what this is, and is not

A near-infrared LED device like CIRIUS is a wellness product, not a drug or a regulated medical device. It is best used alongside management approaches with an established evidence base, stretching, strength work, footwear and insole adjustments, rather than as a substitute for diagnosing or treating a specific condition.

Footwear and Daily Habit Checkpoints

Heel pain is closely tied to how load gets distributed through your shoes and your feet, so adjusting daily habits alone can produce a meaningful improvement.

Choosing footwear

• Cushioning: look for enough padding at the heel, and replace shoes once the midsole has compressed and flattened, typically every three to six months for anything worn daily.
• Arch support: flat feet or a high arch benefit from an insole or a custom orthotic that supports the arch properly.
• Indoor footwear: walking barefoot or in thin slippers on hard flooring for long stretches adds strain to the fat pad; a cushioned pair of house shoes is worth the small investment.

Weight and activity load

• Every extra kilogram adds to the load your heel absorbs with every single step. Keeping weight in a healthy range has a direct, cumulative effect on how much stress the heel is under.
• When increasing running distance or intensity, capping the weekly increase at around 10% helps prevent overuse injury.

Floor surfaces and posture

• If your job has you standing on concrete for long hours, a cushioned mat and periodically shifting your weight or position both help.
• Tight, short calves increase the pull on the plantar fascia, so even small habits, like gently moving your ankles while sitting at a desk, make a difference over time.

Everyday situations worth adjusting

A few specific situations come up often enough to call out directly. Office workers who sit most of the day but then walk long distances at lunch tend to do best stretching calves before that walk, not after. Drivers with a long commute benefit from a brief ankle-circling routine at red lights or before getting out of the car, since a cold, stiff ankle straight out of a seated position loads the fascia harder than a warmed-up one. Parents carrying young children on one hip for extended periods often shift their gait in a way that overloads one heel more than the other; alternating sides deliberately, rather than always favoring the stronger arm, spreads that load back out. And for sleep, a soft mattress that lets the foot sit in a slightly plantarflexed position overnight can leave the fascia shortened by morning, which is part of why some people notice their first-step pain is worse after certain nights than others.

Prevention Strategies to Avoid Recurrence

Heel pain that improves once tends to come back if the habits that caused it in the first place do not change. A few strategies, kept up consistently, make the biggest difference.

Exercise habits

• Before getting out of bed each morning, rotate the ankles a few times and give the sole a light stretch before that first step.
• Add calf and intrinsic foot strengthening (towel scrunches, calf raises) two to three times a week.
• Increase training volume gradually, and give your feet time to adapt when introducing new shoes or a new running surface.

Footwear and insole upkeep

• Consider replacing dedicated running shoes after roughly 250 to 500km of use, or every six months to a year.
• Keep using insoles matched to your foot shape, flat, high-arched, or neutral, consistently rather than only when pain flares.

Periodic check-ins

• Even without pain, runners and anyone who stands for a living benefit from checking foot and calf flexibility every six months.
• Re-evaluate your footwear and insoles whenever your weight or activity level changes meaningfully.
• Keep stretching and wellness care as a standing part of your routine, not just something you reach for once pain shows up; tissue recovery capacity holds up better with that kind of consistency.

Common Myths About Heel Pain

Myth: A heel spur on X-ray means you need surgery

Reality: heel spurs show up often on X-ray, including in plenty of people who have no pain at all. Study after study has found no strong correlation between the presence of a spur and how much pain someone reports; most of the actual pain traces back to the surrounding plantar fascia or soft tissue. Surgery is reserved for the small minority of cases that do not respond to conservative care at all.

Myth: If it hurts, you need to rest completely

Reality: outside the acute inflammatory window, staying active within a pain-free range actually helps tissue recover faster. Complete rest lets calf strength and flexibility deteriorate, which can slow recovery rather than speed it up.

Myth: Young, active people do not get plantar fasciitis

Reality: it is actually runners who ramp up mileage too fast, or anyone who jumps into high-intensity training too suddenly, who show up with this most often. How quickly load increases matters more than age.

Myth: Any pain in the sole of the foot is plantar fasciitis

Reality: fat pad atrophy, nerve entrapment, and stress fractures all live in that same general area. Because the location, pattern, and triggers differ, it is safer to get a professional opinion for anything that persists rather than assuming and self-treating the wrong thing.

Myth: New insoles or shoes alone will fix it

Reality: footwear and insoles reduce load, which helps, but without stretching and strengthening alongside them, the underlying flexibility and strength imbalance stays exactly where it was, which is why pain so often returns a few months after a new pair of shoes seemed to solve everything.
