Headache is one of the most common ailments, experienced by most people several times throughout life. Almost all adults have had a headache, and for many, it is a mild and temporary condition that rarely requires medical attention. However, headaches can vary greatly – from mild discomfort to severe pain that significantly impacts daily life.

Headaches are generally divided into two types: primary and secondary headaches. Primary headache is a condition in itself, such as tension headache, migraine, or the rare cluster headache. Secondary headache is a symptom of another condition, such as infection, fever, head injury, or diseases affecting the brain.

Secondary headaches can arise, for example, as a result of head trauma, sinus infection, high blood pressure, or, more rarely, as a sign of serious conditions such as brain tumor, meningitis, or bleeding in the brain. Warning signs include fever, visual disturbances, paralysis, speech difficulties, or unusually severe headache, all of which should be evaluated by a doctor.

Headaches are rarely dangerous but can be bothersome. However, with recurring or unusual headaches, one should always consult a doctor for a thorough assessment and proper treatment.
