How Do You Diagnose Sinus Headaches Caused by Migraines?
Sinus headaches are most likely due to migraines or tension headaches. Migraines are diagnosed by symptoms, including the frequency and severity of symptoms, family history, and by physical exam. Migraines can also include nausea and vomiting. These episodes may be triggered by hormonal changes, lack of sleep, certain foods or alcohol or caffeine, stress, or environmental changes like weather, altitude changes, or allergens. Many patients with migraines have family members who also experience migraine headaches.
If you have unusual or severe symptoms, additional tests such as an MRI of the brain may be ordered to rule out more serious conditions that can cause headache pain, such as tumors or bleeding around the brain. If you have repeated episodes of sinus pain and pressure, a nasal endoscopy (a pencil-sized scope used to see inside the nose and sinuses) or imaging such as an MRI or CT scan can determine if sinus pain or pressure is due to a sinus infection or other sinus pathology. A normal sinus CT scan while you have symptoms could help rule out sinusitis, and determine if migraines, headaches, or other causes of facial pain and pressure are causing the sinus symptoms.
Other causes of facial pain and pressure can include temporomandibular joint (TMJ) syndrome, clenching or grinding your teeth, trigeminal nerve pain, temporal arteritis (associated with scalp pain, pain in the temple, jaw pain, and vision changes on one side), dental infection, or other neurologic causes of facial pain.
