While many headaches are temporary and improve with rest or hydration, some may indicate an underlying medical condition that requires professional evaluation.
What Is a Headache?
A headache is pain or discomfort in the head, scalp, face, or upper neck. It may range from mild pressure to severe throbbing pain and can last from minutes to several days.
Headaches may occur occasionally or become chronic depending on their cause.
