I have migraine for which doctor had prescribed me Flunarizine 10 mg twice a day but this medicine did not give me any relief of any sort. He also advised me naproxen 500 but I had to discontinue it because I am also suffering from antral gastritis and it causes me trouble when I consume it. Which is the best medicine to treat such headaches and migraine without causing any side effect to any gastro problems ? Plz help.🙏
