Diagnosis of plantar fasciitis is made based on the patient's symptoms and a physical examination by a clinician. Tenderness experienced by the patient may be reproduced by the clinician with flexion of the toes and ankle as well as upward and palpating the length of the fascia.
Plain X-rays may be taken to rule out the presence of heel spurs and other causes of inferior heel pain — like a stress fracture or a bone malformation. Magnetic Resonance Imaging should be taken to rule out soft tissue disease in cases of intractable plantar fasciitis that doesn't get better after conservative management.
