Sharp pain under the heel, worst on the first stride of the morning, easing after a few minutes of walking, then returning after you have been sitting a while. Nobody with this condition has to be asked twice whether that describes them.\n\nThe mechanism behind that pattern is simple. The plantar fascia is a thick band running from the heel bone to the base of the toes, holding up the arch. Overnight your foot rests pointed slightly downward and the band settles short. The first step stretches it abruptly, and the stretch pulls on the damaged tissue at the heel. Walking warms it and it stops complaining. Sitting lets it settle short again, and the next few steps repeat the morning.\n\n## Two things people are told that are not true\n\n**It is not inflammation.** The \"-itis\" in plantar fasciitis is a historical mistake, the same one that mislabelled tendon problems for a century. What is found in the tissue is degeneration and disorganised repair, not inflammatory cells. Some clinicians now say plantar fasciopathy for exactly this reason. It matters because it explains why anti-inflammatory tablets do less than people expect.\n\n**The heel spur is not the problem.** A bony spur on the heel turns up on a large share of X-rays in people with this pain — and on a large share in people with no pain at all. It is a consequence of long-term pull on the bone, not the thing pressing into your foot.\n\n## The scan does not track how you feel, and there is now a study saying so\n\nA 2026 study measured pain, foot function and quality of life alongside the thickness of the plantar fascia on ultrasound, before and three months after shockwave treatment. The results moved apart.\n\n[[embed:source:s1]]\n\nPeople got better while the thickness on the scan barely changed. The authors are careful — no control group, so no causal claim — but the observation stands on its own: the band's measured thickness is not a readout of how the foot feels. If you improve and the follow-up scan looks the same, that is not a treatment failure, and if the scan improves and the foot still hurts, that is not a reason to keep going.\n\n## What predicts a bad outcome is not what most people expect\n\nA 2025 study looked for the factors that predict who stays in pain with chronic plantar heel pain. What came out on top was not weight, not arch height, not how long the pain had lasted. It was what people believed about their pain, and whether the pain had nerve-like features — burning, tingling, shooting.\n\n[[embed:source:s2]]\n\nIn the full model, nothing else was significantly associated with pain.\n\nTwo practical consequences. First, if your heel pain burns or shoots rather than aching sharply, that is a signal worth naming to a clinician, because it points somewhere other than a straightforward fascia problem — a compressed nerve in the foot can imitate this closely. Second, catastrophic beliefs about the pain are a treatable target, and treating them is not a suggestion that the pain is imaginary. It is a finding about what predicts the next six months.\n\n## The treatment order that the evidence supports\n\nStart with the least invasive things that work and escalate only if they fail. That is not a platitude — it is the explicit conclusion of a 2025 framework that sorted thirty treatments into stages.\n\n[[embed:source:s3]]\n\nSurgery sits at the end of that sequence and reaches very few people.\n\nFor the injections and devices in the middle of it, a 2026 network analysis compared them against each other and produced a genuinely useful split.\n\n[[embed:source:s4]]\n\nRead that carefully, because it is a timing argument rather than a winner. Steroid gives the biggest early gain in function. Platelet-rich plasma is where the longer-term improvement is. And shockwave was the one treatment that performed across all measures and all timepoints rather than winning one and fading.\n\nIf you are choosing, the question is which of those shapes fits your pro","ranking":"safety-first (interaction_risk/limitations), then quote-gated effective_weight","claims":[{"id":"c1","text":"Ultrasound appearance dissociates from how the patient actually feels after treatment, so imaging does not track recovery.","tier":"observational","interaction_risk":false,"status":"active","source_ids":["s1"],"source_status":"sourced","why_material":"It stops people chasing a scan that will not improve on the same timeline as their symptoms, and stops a still-abnormal image being read as failed treatment.","retracted_at":null,"retraction_reason":null,"challenged_by":[],"effective_weight":0.1,"quote_gated":false},{"id":"c2","text":"Pain catastrophizing beliefs and neuropathic symptoms are associated with worse outcomes, so what predicts a bad result is not what most people expect.","tier":"observational","interaction_risk":false,"status":"active","source_ids":["s2"],"source_status":"sourced","why_material":"The modifiable predictor is psychological and neuropathic rather than structural, which points at a different and more effective intervention than the one people reach for.","retracted_at":null,"retraction_reason":null,"challenged_by":[],"effective_weight":0.1,"quote_gated":false},{"id":"c3","text":"An evidence-based treatment framework exists for plantar heel pain and supports a specific order of treatments.","tier":"expert","interaction_risk":false,"status":"active","source_ids":["s3"],"source_status":"sourced","why_material":"The order is the whole value.
