Tests and diagnosisBy Mayo Clinic staff
To make a diagnosis of plantar fasciitis, your doctor reviews your medical history and physically examines your foot. An imaging test might be needed, too.
During the physical exam, your doctor checks for points of tenderness in your foot. The location of your pain can help determine if it's caused by other problems.
Your doctor may also check the musculoskeletal and neurological health of your ankle joint and foot by testing your:
- Muscle strength
- Muscle tone
- Senses of touch and sight
Your doctor may suggest an X-ray or magnetic resonance imaging (MRI) to make sure your pain isn't being caused by another problem, such as a stress fracture or a pinched nerve.
Sometimes, an X-ray shows a spur of bone projecting forward from the heel bone. In the past, these bone spurs were often blamed for heel pain and removed surgically. But many people who have bone spurs on their heels have no heel pain.
