I think I have signs of an annurism? help me out here....?

thats why I ask buddy. I know how serious it is. I know all too well, but I deal with VA, so its not like walking into a regular doctor and having an appointment the next day. I want to know before I go through the crap of making an appointment and driving 38 miles to find out that its somthing that cant be tested for. so clam down. Im not looking for a lecture on what to ask and what not to ask, Im looking for some help here. My brother dropped dead from one, and if it werent for him, I would never be suspecting anything but a regular headache.

I guess I should have been more specific about the headaches. I am not a person to normally have headaches. on the rare occasion that I do, it actually concerns mebecause its so uncommon for me to. maybe 2 times a year I get one. This headache is more localized and acute right at the back of my head just above my stem area. I guess I am hoping for the best case scenerio, but now knowing that I can be tested for one and they can be found, thats a relief in itself. I havent thought that it was identifiable because I hear of people dropping from them so i have always wondered why I never hear of people checking for them and opting for prevention.
