I have this pain above my left eyebrow near the center of my forehead for about 3 days now, it comes and goes.. it feels like something is applying pressure on it.. as far as i know, i have not been hit by anything or bumped to anything.. i don t have cold, but had caught a flu a week ago, i tried pain relievers but it always comes back in about an hour.. if i sit after standing for about 10 minutes, the pain worsens and vice versa.. help please?
