Key facts
Plantar fasciitis at a glance.
The essentials, in plain English — what plantar fasciitis is, why it hurts on that first morning step, and what the evidence says actually helps.
-
Definition
Plantar fasciitis is a chronic plantar fascia enthesopathy — a degenerative and inflammatory change where the fascia inserts into the heel bone.
-
Classic symptom
Sharp heel pain, worst on the first steps out of bed in the morning — easing after a few minutes of walking.
-
When to image
Ultrasound or MRI confirms the diagnosis if the presentation is uncertain or the pain is refractory to conservative care.
-
Rehab is core
Structured plantar fascia and calf stretching remain the cornerstone of treatment — dull, unglamorous and effective.
-
Shockwave works
Extracorporeal shockwave therapy (ESWT) has real evidence for refractory cases — usually 3–6 sessions over several weeks.
-
Injections — care
Cortisone injection carries a small plantar fascia rupture risk — image-guided injection is strongly preferred.
Why this guide matters
Rehab first, injections last.
Plantar fasciitis usually settles with patient, consistent rehab — this guide sets out that order clearly so nobody skips ahead too fast.
-
Stretching beats any single injection
Structured plantar fascia and calf stretching, done consistently, outperforms any single shot over the medium term.
-
Orthoses are a real intervention
Silicone heel cups and arch support cut fascia load — cheap, immediate and evidence-backed as first-line care.
-
Shockwave when things stall
For refractory cases, extracorporeal shockwave therapy has genuine evidence — well before considering surgery.
How the diagnosis is made
From painful heel to a clear plan.
The steps a UK GP will normally follow, in order — so you know what to expect and why.
Phase 1 · Recognising
Symptoms, examination and selective imaging
Phase 2 · Confirming
Ultrasound / MRI and podiatry for atypical cases
Phase 3 · Managing
Physio first, specialist if refractory
- 01
Recognising
Symptom pattern
The story does most of the work — sharp heel pain, worst on the first step in the morning, easing with walking then returning after standing.
- 02
Recognising
Foot examination
Tenderness at the medial calcaneal tubercle, tight calf, restricted ankle dorsiflexion — the classic examination triad.
- 03
Recognising
X-ray if trauma or bony concerns
Not routine for typical plantar fasciitis, but useful to exclude calcaneal stress fracture or other bony pathology.
- 04
Confirming
Ultrasound / MRI for atypical cases
Reserved for uncertain diagnosis, bilateral pain in a young man, or symptoms not responding to first-line care.
- 05
Confirming
Podiatry assessment
Biomechanical review, orthotic prescription and footwear advice — often the highest-value intervention.
- 06
Managing
Physiotherapy programme
A structured stretching and loading programme — the single most useful long-term intervention.
- 07
Managing
Consider referral
For refractory cases — shockwave, image-guided injection or, rarely, surgical release with a foot and ankle specialist.
Typical timeline: 2–4 weeks from first appointment to a settled plan.
Symptoms
What plantar fasciitis actually feels like.
The pattern is more telling than any single symptom — first-step morning pain, sharp heel discomfort and long-standing aggravation.
-
Sharp heel pain
A pinpoint, stabbing pain at the underside of the heel — classic for plantar fasciopathy.
-
Worst first-step morning
The most telling symptom — the first few steps out of bed are the worst, easing as the fascia warms.
-
Foot arch discomfort
A dull ache along the medial arch of the foot, often after prolonged activity.
-
Aggravated by long standing
Prolonged standing, walking on hard floors or a long day on your feet reliably flares symptoms.
-
Bilateral or unilateral
Usually one heel but can affect both — bilateral pain in a young man warrants an inflammatory arthritis screen.
-
Tight calf
Restricted ankle dorsiflexion and a tight gastrocnemius are commonly found and strongly linked.
-
Weight-related
Excess body weight increases fascia load — modest weight loss often improves symptoms alongside rehab.
-
Red flag
Heel pain with fever or systemic symptoms — rule out inflammatory arthritis (spondyloarthropathy) rather than assuming plantar fasciitis.
Treatment
How plantar fasciitis is treated in the UK.
A staged approach — rehab and orthoses first, then shockwave and image-guided injection, with surgery reserved for genuinely refractory disease.
-
Structured stretching
Plantar fascia and calf stretching, done daily — the single most evidence-based intervention over months, not weeks.
-
Silicone heel cups + arch support
Simple off-the-shelf orthoses cushion the heel and support the arch — a cheap, useful first step.
-
Night splints
Hold the fascia and calf on gentle stretch overnight — helpful for the classic first-step morning pain.
-
Physiotherapy programme
Tailored stretching, eccentric calf loading and progressive loading of the fascia — the backbone of long-term recovery.
-
Extracorporeal shockwave (ESWT)
A course of shockwave therapy — real evidence for refractory cases when 6+ months of rehab has not settled things.
-
Ultrasound-guided cortisone injection
Short-term relief for stubborn cases — image-guided to minimise the small but real risk of plantar fascia rupture.
-
Platelet-rich plasma (PRP)
An option in specialist hands — evolving evidence, sometimes considered when steroid has failed and surgery is being weighed.
-
Surgical release
Rare and reserved for genuinely refractory disease — a last resort after all conservative measures have been exhausted.

Red flags
When heel pain is not just plantar fasciitis.
Most heel pain is mechanical and settles with rehab. These are the situations where a different diagnosis needs to be considered.
-
Bilateral heel pain in young man
Consider an ankylosing spondylitis screen — bilateral enthesopathy in a young adult is a classic pointer.
-
Diabetic ulcer
A non-healing plantar ulcer in a person with diabetes needs urgent podiatry and diabetic foot team review.
-
Post-injection rupture
Sudden sharp pain with a palpable defect after a steroid injection — suggests plantar fascia rupture, needs review.
-
Infection at injection site
Increasing pain, redness, swelling or fever days after any injection — same-day review.
-
Neurological signs (tarsal tunnel)
Burning, tingling or numbness in the sole suggests tarsal tunnel syndrome, not plantar fasciitis.
-
Weight loss with heel pain
Unexplained systemic weight loss with heel pain — investigate for inflammatory or malignant causes.
-
Post-op complications
New pain, swelling, warmth or wound problems after plantar release surgery — contact your surgical team.
-
Chronic pain sensitisation
Pain out of proportion to findings, spreading beyond the fascia — needs a broader pain assessment, not more injections.
-
Post-fracture non-union
Persistent heel pain after a known calcaneal fracture may reflect non-union — imaging and orthopaedic review.
Living with it
A slow condition, but a very manageable one.
Four things that make the biggest difference day to day — rehab, footwear, load management and patient review.
A quiet reminder
Consistency beats intensity, every time.
Small, steady changes — kept up for months — do more than a heroic week that does not last.
- 01 Rehab
Do the stretching, daily
Plantar fascia and calf stretches done consistently over months — dull, unglamorous and the single biggest lever.
- 02 Footwear
Support your feet
Supportive, cushioned shoes indoors and out — avoid barefoot walking on hard floors, especially first thing.
- 03 Load
Manage standing time
Long days on hard floors reliably flare symptoms — break up standing time and modify high-impact activity while healing.
- 04 Reviews
Reassess in weeks, not days
Rehab and orthoses take weeks to work — reassess at 6–12 weeks, and consider shockwave if things have not settled.
Frequently asked
Everything we get asked about plantar fasciitis.
Quick answers on stretching, orthoses, shockwave, injections and when to seek help.
-
What actually causes plantar fasciitis?
It is a degenerative and low-grade inflammatory change at the point where the plantar fascia inserts into the heel bone. Repetitive load, tight calves, prolonged standing and higher body weight are the main drivers — not a single injury.
-
How long does it take to get better?
Most cases settle over 6–12 months with consistent rehab, stretching and orthoses. It is genuinely slow — reassuring people that this is normal is a big part of managing it well.
-
Do I need a scan?
Not usually. The diagnosis is clinical. Ultrasound or MRI is reserved for uncertain cases, bilateral heel pain in a young adult, or symptoms that have not responded to several months of good conservative care.
-
Does shockwave therapy actually work?
Yes — extracorporeal shockwave therapy (ESWT) has real evidence for refractory plantar fasciitis. It is typically offered after 6+ months of failed conservative care, as a course of 3–6 sessions.
-
Are cortisone injections safe?
They can give useful short-term relief but carry a small risk of plantar fascia rupture and heel-fat-pad atrophy. Where used, image-guided injection is strongly preferred to reduce that risk.
-
What is the red flag I should not ignore?
Bilateral heel pain in a young man, heel pain with fever or systemic symptoms, or new neurological signs in the foot — these need review to exclude inflammatory arthritis, infection or tarsal tunnel syndrome.
