Get StartedTests and diagnosis
By Mayo Clinic staffIf you have chronic or recurrent headaches, your doctor may try to pinpoint the type and cause of your headaches using these approaches:
- Your description of your pain. Your doctor can learn a lot about your headaches from your description of the type of pain, including its severity, location, frequency and duration, and other signs and symptoms you may have.
- Imaging tests. If you have unusual or complicated headaches, your doctor may order tests to rule out serious causes of head pain, such as a tumor or an aneurysm. Two common tests used to image your brain are computerized tomography (CT) and magnetic resonance imaging (MRI) scans. A CT scan is a diagnostic imaging procedure that uses a series of computer-directed X-rays to provide a comprehensive view of your brain. An MRI doesn't use X-rays. Instead, it combines a magnetic field, radio waves and computer technology to produce clear images.
- A headache calendar. One of the most helpful things you can do is keep a headache calendar. Each time you get a headache, jot down a description of the pain, including how severe it is, where it's located and how long it lasts. Also note any medications you take. A headache calendar can offer valuable clues that may help your doctor diagnose your particular kind of headache and discover possible headache triggers.
