Hi there! I got a headache, heavy one, in my forehead area. It makes my eyes hurt too. Really hard to concentrate my vision, and it s big problem because I am a student. My friend suggested that this kind of pain on the top area of head can be because of high blood pressure. My blood pressure is usually low, so I drink 1 cup of coffee a day. So I stopped doing it for the past few days, but I am still having the headache. Also I feel fewerish, only my head though, hands and feet are cold. A little higher level of sweating that usual. Otherwise no other indicators of sickness. What can this be? Thank you!
