I actually went to the dr. just last week with a horrible headache. I have miagranes, but this wasn't a miagrane; it was one of those that you feel every heartbeat!
I had it for like a week off and on...and this one day I just couldn't stand it anymore. My blood pressure was through the roof, and my pressure is usually normal. She gave me a shot, don't have a clue what it was, but I'm going to find out if it comes in pill form. The headache was gone in less than an hour. We decided it was all from stress! Work has been a mess and got the best of me. Please have it checked out if you think your blood pressure might be involved; that's nothing to fool with. Good luck!
