for about the past 2 weeks now i have had a pressure at the base of my skull, constantly. and off and on through out the day i get pain at the front of my head. i am taking pain killers for it, it does help but the pain just comes back. i dont really feel the pain in the morning. i dont kno what to do. i hav changed my diet, my sleeping times. i had an eye exam recently and they are fine so i dont know what could be causing these pains.
