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.

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.
Other causes of heel pain that can mimic plantar fasciitis.
Pain at the BACK of the heel rather than the underside. Often worse going up stairs or hills.
Tingling or numbness alongside the pain. Can radiate into the arch and toes.
Constant pain that does NOT ease with gentle walking. Often follows a sharp increase in running or load. See your GP.
Sudden severe pain, swelling, redness and warmth — often with possible fever. Needs urgent medical assessment.
