Heel pain has at least five common causes, each with its own pattern. The pain that hits first thing in the morning is not the same condition as the pain that builds during the day, or the burning at the back of the heel after a long run. This decision tree walks you from your pattern to the most likely cause.
The aim is not to replace a clinical diagnosis. The aim is to give you a working hypothesis so the conversation with your podiatrist starts further down the road.
Pick the pattern that fits you best. If two patterns fit, read both. Heel pain in real life is sometimes more than one thing at once.
First-Step-In-The-Morning Pain (Likely Plantar Fasciitis)
The signature pattern:
- Sharp, stabbing pain in the first few steps when you get out of bed.
- Pain eases after a few minutes of walking, then often returns later in the day after sitting for a while.
- Tenderness localises to the underside of the heel bone, slightly toward the inside of the foot.
- The pain is reproducible if you press firmly on that spot.
This is the classic presentation for plantar fasciitis. The mechanism: the plantar fascia (the connective tissue band running along the underside of the foot) tightens up overnight and the first few steps load it before it has rewarmed. Pain at first step, easing with movement, then worsening with cumulative load is the fingerprint.
What pushes the case stronger: a recent jump in walking volume, long days standing, footwear that has lost its support, or a history of tight calves.
What it is not: pain at the back of the heel (that is Achilles), deep bruised pain (that is fat pad), or burning sensation (that is nerve).
Pain at the Back of the Heel (Likely Achilles Tendonitis or Haglund's)
The signature pattern:
- Pain located at the back of the heel, where the Achilles tendon attaches to the heel bone, or slightly above.
- Stiff and sore on first steps in the morning, but the pain stays at the back of the ankle rather than under the foot.
- Aggravated by uphill walking, stairs, or pushing off the foot during running.
- Sometimes a visible bump at the back of the heel bone that rubs against shoe counters.
Two conditions sit in this pattern. Achilles tendonitis is irritation of the tendon itself, usually from a load that exceeded its tolerance (sudden running volume, hill work, returning to sport after a break). Haglund's deformity is a bony prominence at the back of the heel that becomes painful when it rubs against rigid shoe counters.
Both can coexist. The key disambiguation: if you press on the tendon itself and reproduce the pain, the tendon is involved. If the pain is on the bone behind the tendon and is worse in stiff shoes, the bony prominence is in the mix.
Deep Bruised Ache Under the Heel (Likely Fat Pad Syndrome or Stress Fracture)
The signature pattern:
- A deep, bruised feeling under the heel rather than a sharp pain.
- Worse walking barefoot or in thin-soled shoes, particularly on hard surfaces.
- Pain that builds with longer periods of walking or standing rather than easing.
- Sometimes radiates to the sides of the heel.
Two conditions to disambiguate here:
Heel fat pad syndrome is contusion or thinning of the fatty cushion that normally absorbs heel-strike load. Common in patients who have had repeated heavy heel strikes, who stand long hours on hard floors, or who have lost some of the natural fat pad density over time.
A calcaneal stress fracture is a bony stress injury within the heel bone itself, typically triggered by a recent ramp in load (new running programme, sudden increase in walking, military-style training). The pain is more focal, often reproducible by squeezing the heel from the sides, and does not settle with rest in the way a soft-tissue irritation would.
Stress fracture is the higher-stakes diagnosis here. If your pain has a clear "I increased my training and then this started" story and is not settling with normal load reduction, this pattern needs a clinical assessment rather than continued self-management.
Burning or Tingling Around the Heel (Likely Baxter's Nerve Entrapment)
The signature pattern:
- Burning, tingling, or electric quality to the pain, rather than a sharp or aching pain.
- Often felt on the inside of the heel, sometimes radiating into the arch.
- Can be present at rest or at night, not just under load.
- May coexist with or be mistaken for plantar fasciitis.
This is the pattern of Baxter's nerve entrapment, where a small branch of the tibial nerve becomes compressed as it passes through the soft tissue under the heel. The reason it gets missed: it lives in the same neighbourhood as plantar fasciitis and is sometimes carried alongside it.
The disambiguating feature: the quality of the pain. Sharp and stabbing on first steps is fascia. Burning, tingling, or "different" sensation is nerve. If a patient has been treated for plantar fasciitis without improvement, and the pain has a nerve quality to it, this diagnosis becomes more likely.
Pain in Active Children Aged 8-14 (Likely Sever's Disease)
The signature pattern:
- Pain at the back of the heel in a child who is active in sports.
- Worse during and after training, eases with rest.
- Often bilateral (both heels) although one side is usually worse.
- Child may walk on toes after a game to avoid heel-strike.
- Squeeze test (pinching the sides of the heel bone) reproduces the pain.
This is paediatric heel pain, commonly called Sever's disease, and it is a load-related irritation at the growth plate at the back of the heel bone. It is common in active children during growth spurts and resolves once the growth plate closes, although the management in the meantime matters because pain can sideline a child from sport for months if it is not addressed.
The diagnostic confidence is high in this age group with this pattern. The plan involves load modification, heel-cushioning footwear changes, and a targeted exercise programme to manage symptoms while growth continues.
When the Pattern Doesn't Fit
Real-world heel pain sometimes fits more than one box, or doesn't fit any of them cleanly. Patterns that warrant a clinical assessment rather than self-management:
- Pain that started suddenly during exercise with a pop or snap, followed by inability to push off.
- Pain that is present at rest, at night, or wakes you up.
- Pain accompanied by swelling, redness, warmth, or feeling generally unwell.
- Pain that has not responded to two to three weeks of sensible self-management.
- Pain that does not localise to a single region (it moves, or feels diffuse).
- Pain on a diabetic foot, regardless of pattern.
In any of these scenarios, the question stops being "which pattern is this" and starts being "what is going on here", which is the diagnostic question a podiatry consultation is built to answer.
