I'm 16 and had migraines for months and tried many medication but they didn't work and ruled out sinus. What should I do next? What can it be?

Migraine treatment. Once a diagnosis of migraine has been made, effective management of migraine involves three specific strategies: 1) patient education, 2) nonpharmacological management, and 3) pharmacological (medical) management. See an orofacial pain or headache specialist for evaluation and professional management.
