What plantar heel pain is

The plantar fascia is a thick band of connective tissue running from the heel bone to the base of the toes, forming the arch of the foot and storing and returning energy with every step. Plantar fasciopathy, still widely called plantar fasciitis, is a degenerative and pain-related change where it attaches to the heel.

The pattern is distinctive: sharp, localised pain under the inside of the heel, worst on the first few steps after sleeping or after any long sit, easing over five to ten minutes of walking, and often returning with a dull ache by the end of a long day.

Heel spurs are frequently blamed and rarely the cause. They appear on x-ray in a substantial proportion of people with no heel pain at all, and removing them does not reliably relieve symptoms.

What causes it

The tissue is responding to accumulated load. That load can arrive through running volume, through a job spent standing on hard floors, or through a sudden increase in daily walking, which is why a week of city sightseeing is such a common trigger.

Bodyweight matters mechanically here more than in most tendon problems, and reduced ankle dorsiflexion is a well-established risk factor, since a stiff ankle shifts more load onto the forefoot and fascia.

Common contributors

  • A rapid increase in walking or running volume
  • Long hours standing on hard surfaces, particularly in flat unsupportive shoes
  • Reduced ankle dorsiflexion or a tight calf complex
  • Weakness in the small muscles of the foot and in the calf
  • A change of footwear, especially to something much flatter than usual
  • Raised body weight, which increases load through the fascia with every step
💡 Clinical insight

Morning pain on the first steps is the marker worth tracking, because it reflects how the tissue responded to yesterday's total load rather than how it feels right now. Ask someone to rate those first steps out of ten each morning for a fortnight and the pattern usually shows exactly which days were too much. That log is often more useful than anything found on examination.

What the evidence says

High-load plantar fascia specific strength training, performed as a slow heel raise with the toes extended over a rolled towel, has good trial evidence, with a randomised study showing superior outcomes at three months compared with stretching alone.

Calf and plantar fascia stretching gives useful short-term relief, particularly for the morning symptoms, and works best combined with strength work rather than used on its own.

Orthoses and supportive footwear produce modest short-term improvements. Prefabricated insoles perform about as well as custom ones in most trials, which is worth knowing before paying for bespoke.

Extracorporeal shockwave therapy has reasonably strong evidence for chronic plantar heel pain that has not responded to several months of conservative treatment, with multiple trials showing reduced pain and improved function.

Corticosteroid injection gives short-term relief with a recognised risk of fascial rupture and fat pad atrophy, which keeps it as a limited option rather than a routine one.

Recovery timeline

This is a slow condition and setting expectations honestly matters. Around 80 per cent resolve within a year, and typical recovery with active treatment runs three to six months. Cases that have already been going a year commonly take six to twelve months more.

Progress shows up as a shorter morning episode before it shows up as less pain overall. Fifteen minutes of morning discomfort dropping to five is real progress.

Stage ✓ Do this ✗ Avoid this
Weeks 1–3 Morning calf and fascia stretch before the first steps. Supportive shoes indoors. Reduce standing and walking volume slightly. Barefoot on hard floors, or rolling aggressively on a frozen bottle as the only treatment
Weeks 2–12 High-load heel raises with toes extended, every other day, progressing weight steadily. Stretching alone for three months
Weeks 8–16 Graded return to walking and running volume, roughly 10 per cent a week, with a down week every fourth. Returning to full mileage as soon as the morning pain goes
If stuck at 3–4 months Reassess. Shockwave is a well-supported next step at this point. Repeating the same programme unchanged for another three months

How we treat it at Kingsway

Treating persistent heel pain

The assessment confirms the diagnosis, checks ankle range and calf capacity, and rules out the conditions that mimic it, including nerve entrapment and a calcaneal stress fracture.

  • Palpation and load testing to confirm the source, with a screen for stress fracture and nerve involvement
  • Ankle dorsiflexion measurement and calf strength testing
  • Soft tissue release and IASTM through the calf, soleus and plantar fascia
  • Dry needling into the calf and intrinsic foot muscles where trigger points refer into the heel
  • Radial shockwave therapy for cases past three months, which is where the evidence is strongest
  • A high-load strength programme plus footwear and load advice

Where shockwave is used, a course of three to five weekly sessions is standard, alongside the loading programme. Most people need treatment spread over three to four months, which is what the five or ten session packages are for.

When to get it checked

Book an assessment if heel pain has lasted more than four weeks or is changing how you walk. Get seen sooner if the pain is spreading across the whole heel rather than staying at one point, if there is numbness or burning in the foot, or if it hurts when you squeeze the heel bone from both sides.

See a doctor or go to A&E if

  • Pain on squeezing the heel bone from both sides, which can indicate a calcaneal stress fracture
  • Numbness, burning or pins and needles in the sole of the foot
  • Heel pain in both feet at once in a younger adult, alongside back or joint stiffness
  • Marked swelling, redness or heat around the heel
  • Sudden severe pain during activity with immediate inability to weight-bear

Common questions

Is it really plantar fasciitis?

The morning-first-steps pattern with a single tender point on the inside of the heel is characteristic, and most cases are straightforward.

Pain spread across the whole heel, night pain, burning or numbness, or tenderness when squeezing the heel from both sides all point elsewhere and are worth getting assessed.

Do I need custom orthotics?

Probably not. Trials comparing prefabricated insoles with custom-made ones generally find similar results, and both give modest short-term relief.

A supportive shoe worn indoors, where most people are barefoot on hard floors, often does more than an expensive insole worn only outdoors.

Should I roll it on a ball?

Gentle rolling can ease symptoms and is fine as comfort work. Aggressive rolling on a frozen bottle sometimes aggravates an already irritable attachment.

It does not build capacity, so it works as an adjunct to the strength programme rather than as a substitute for it.

How long until I can run again?

Many people keep running at reduced volume throughout, using the same pain rule as for the Achilles: up to about 5 out of 10 during the run, settled by the next morning.

A return to full volume usually comes at around three to four months, built back at roughly 10 per cent a week.

Get this assessed properly

This page describes the pattern. An assessment tells you which part of it is yours, what stage you are at, and how hard you can push this week.
