Tests and diagnosis

By Mayo Clinic Staff

Your doctor will probably do a physical exam to check for signs of illness, infection or neurological problems. If the cause of your headaches remains uncertain, you may need blood or urine tests to identify any underlying medical conditions. Sometimes imaging studies — such as a computerized tomography (CT) scan or magnetic resonance imaging (MRI) scan — are recommended. An electroencephalogram (EEG) can also help diagnose brain tumors, injury or inflammation.
