Hello, You are experiencing palpitations and flutters along with headaches since a week. Headaches and heart palpitations are common symptoms of several conditions, such as anxiety disorders, low blood pressure, and dehydration. Drinking caffeine or alcohol with meal may cause palpitations and headaches. Caffeine and alcohol withdrawal also causes headache and palpitations.
