Self assessment

Is It Plantar Fasciitis?

Plantar fasciitis has a very specific and recognisable pattern. This guide uses the same diagnostic criteria NHS clinicians apply to help you understand whether your symptoms are consistent with the condition.

Important: This self-assessment is for general guidance only. It is not a medical diagnosis. If you are unsure about your symptoms or if they are severe, please see your GP or self-refer to NHS physiotherapy for a proper assessment.

The Windlass Test: A Clinical Assessment

How to try it at home

  1. Sit or stand with your foot relaxed.
  2. Extend the big toe upward — pull it gently toward you.
  3. If this reproduces or worsens your heel pain, it is a positive result.

A positive Windlass Test is a strong indicator of plantar fasciitis and is used routinely by NHS physiotherapists and podiatrists.

Note: this is a clinical test. A physiotherapist will perform it properly. The home version gives a rough guide only — it is not a formal diagnosis.

Conditions to Rule Out

Other causes of heel pain that can mimic plantar fasciitis.

01

Achilles Tendinitis

Pain at the BACK of the heel rather than the underside. Often worse going up stairs or hills.

02

Tarsal Tunnel Syndrome

Tingling or numbness alongside the pain. Can radiate into the arch and toes.

03

Heel Stress Fracture

Constant pain that does NOT ease with gentle walking. Often follows a sharp increase in running or load. See your GP.

04

Gout

Sudden severe pain, swelling, redness and warmth — often with possible fever. Needs urgent medical assessment.

Frequently Asked Questions

Do I need an X-ray to confirm plantar fasciitis?
Usually not. Plantar fasciitis is a clinical diagnosis based on symptoms and examination. NHS guidance does not recommend routine imaging. X-ray or ultrasound is typically reserved for atypical cases or when conservative treatment has failed.
Can a GP diagnose plantar fasciitis?
Yes — most cases are diagnosed by a GP, physiotherapist or podiatrist on the basis of history and examination. Many NHS Trusts also accept self-referral to musculoskeletal physiotherapy without going through a GP.
My pain is not exactly like the description — could it still be plantar fasciitis?
Possibly. Symptoms vary between people and not everyone has the textbook morning pain. If you have heel pain that is not improving after 2–3 weeks of self-care, see your GP or self-refer to physiotherapy.
Is there a blood test for plantar fasciitis?
No. There is no blood test that confirms plantar fasciitis. Bloods may occasionally be used to rule out other causes such as inflammatory arthritis or gout if the picture is atypical.
