How Can I Tell If My Headache Is Serious?

Most headaches are harmless, but some require medical attention. Warning signs include sudden, severe pain (“thunderclap” headache), fever, stiff neck, confusion, vision problems, weakness, or headaches after a head injury. Frequent or worsening headaches, especially with nausea or vomiting, should also be evaluated. If pain differs from your usual pattern or disrupts daily life, consult a doctor. While medications vary by condition, treatments like nitazoxanide 500mg are not for headaches but for infections, so avoid self-medicating. Staying hydrated, resting, and managing stress can help mild headaches, but serious symptoms demand prompt medical care immediately.
