Diagnosis of Plantar Fasciitis
Plantar fasciitis is diagnosed based on the history of the condition as well as the physical examination. Plantar fasciitis will have localized tenderness along the sole of the foot, most commonly at the inside arch of the heel. Usually no further testing is necessary. X-ray testing can reveal an associated heel spur if present and rule out other causes of heel pain, such as fractures or tumors. Ultrasound imaging can also be helpful in diagnosing plantar fasciitis.
