A headache is a common condition characterized by pain or discomfort in the head, scalp, or neck. It can be primary, such as migraines, tension headaches, or cluster headaches, or secondary, caused by underlying conditions like sinus infections, head injuries, or high blood pressure. Symptoms vary from dull, aching pain to sharp, throbbing discomfort and can be accompanied by nausea, sensitivity to light or sound, and visual disturbances. Triggers include stress, dehydration, lack of sleep, and certain foods. Treatment depends on the type and cause, ranging from over-the-counter pain relievers to prescription medications and lifestyle changes.
