I generally have a headache once every 15 days. Is this normal?
Having a headache once in about 15 days can be normal for many people, especially if it is mild and goes away with rest, water, or a simple painkiller. Common triggers include stress, dehydration, poor sleep, long screen time, or sinus issues. But if the headaches are getting more frequent, very painful, or come with vomiting, vision changes, or dizziness, it is best to get checked by a doctor to rule out migraine or other causes.
