ok i have those weird head aches well when i shake my head up and down i have mild pain weird feeling back and right? side of my head ... i dont have vision problems or dizzines or anything . it goes away during work out . also it gets worse when i wrestle cuz i roll over my head and staff... last time i did phisical was in 2008 feb and was totally fine ... what is it? should i worry about it? it only hearts when i shake my head ! or hit my head ... pain is not even that bad but it is annoying ...
