This afternoon it started, I got a pain on the top, a little to the right side of my head. This was 6 hours ago and it comes on and off. I don't have a headache though, just sharp, stabbing pains that when they come are pretty bad. I don't mind the pain, but this is scaring me. I don't have other symptoms like light sensitivity or fever, or nausea, anything that would indicate a hemorrhage, stroke or something serious. I know I have felt this before but not all day. What could this be, and has anyone had this?
