Headache is one of the most common reasons people seek medical advice. Most headaches are primary headaches, such as tension-type headache or migraine, and are not caused by an underlying structural disease. However, some headaches can be a symptom of a more serious condition and should not be ignored.
Common Causes of Headache
Tension-type headaches commonly cause a dull, pressing or tightening pain, often on both sides of the head. They may be associated with stress, fatigue, poor sleep, or prolonged screen use.
Migraine typically causes moderate to severe, often throbbing pain and may be accompanied by nausea, vomiting, or sensitivity to light and sound. Some people experience visual or sensory symptoms called an aura before the headache.
Other common triggers include dehydration, missed meals, infections, excessive caffeine, alcohol, and inadequate sleep.
When Should a Headache Concern You?
Certain features require prompt medical assessment. These include a sudden, extremely severe headache, a new headache with fever and neck stiffness, confusion, seizures, fainting, persistent vomiting, or new neurological symptoms such as weakness, numbness, difficulty speaking, or significant vision changes.
A new or progressively worsening headache, particularly in an older adult or in someone with a history of cancer or immune suppression, also warrants medical evaluation.
What Can You Do?
Adequate hydration, regular meals, sufficient sleep, physical activity, and stress management can help reduce headaches. Keeping a headache diary may help identify recurring triggers.
Pain-relieving medicines can be useful when appropriately selected, but frequent self-medication should be avoided because overuse of acute headache medicines can itself contribute to frequent headaches.
Take-Home Message
Most headaches are manageable, but the pattern and associated symptoms matter. If your headache is new, unusually severe, recurrent, or accompanied by warning signs, consult a doctor for appropriate evaluation rather than relying on self-medication.
