Exams and Tests
To diagnose
plantar fasciitis, your doctor will ask questions
about your symptoms and your past health. He or she will also do a
physical exam of your feet that includes watching you
stand and walk.
X-rays are not helpful in diagnosing plantar
fasciitis, because they do not show ligaments clearly. But your doctor might
take X-rays if he or she suspects a
stress fracture, bone cyst, or other foot or ankle
bone problems. X-rays may show whether a
heel spur is present, although a bone spur does not
necessarily mean that a person has plantar fasciitis.
If the
diagnosis is not clear, you may have other tests. Tests that are done in rare
cases include
MRI, blood tests, bone scans, and vascular testing,
which can evaluate blood flow in the foot and lower leg. If your doctor
suspects nerve entrapment, you may have neurological testing.
