A migraine, cluster headache, or more serious conditions like hemorrhage or stroke could be the source of sudden, intense head pain that is not accompanied by stress. Weakness, altered eyesight, disorientation, or vomiting are additional warning indicators. To rule out any critical illnesses, get medical help right away.

A week-long, intense headache is abnormal and requires medical attention. Migraines, infections, hypertension, or other neurological conditions are possible causes. See a physician right away to identify the reason and receive the necessary care.
