What Are the Symptoms of Headache?
Primary Headache
Symptoms of migraines include pulsating or throbbing pain on one side of the head, sensitivity to light, sound, and sometimes smells and touch, nausea and vomiting, blurred vision, and occasionally lightheadedness that could lead to fainting.
Tension headaches typically involve a dull, aching head pain with a sensation of tightness or pressure across the forehead or on the sides and back of the head. It could also lead to tenderness on the scalp, neck, and shoulder muscles.
Symptoms of cluster headaches include intense burning or piercing pain behind or around one eye, watery eye, and nasal congestion on the same side as the pain.
Secondary Headache
Secondary headaches exhibit symptoms that vary based on the underlying cause, such as fever, neck stiffness, or sinus pressure, in addition to the typical headache pain.
When to Seek Urgent Medical Attention
Seek emergency care immediately for: a sudden thunderclap headache (the worst headache of your life, reaching maximum intensity within seconds), headache with fever, stiff neck, and rash (possible meningitis), headache with sudden weakness, vision loss, or speech difficulty (possible stroke), headache following a head injury, and progressive headache worsening over days or weeks in someone over 50. These require emergency neurological assessment.
