Thanks to all of you for your response. Fifteen years ago, I had a massive ruptured brain aneurysm which was clipped with a large aneurysm clip. I would have to look up the size on the surgery report. I have had absolutely no problems since that time. Recently, I have begun to have some minor headaches again. I have been told that aneurysms are bilateral and usually recur after about 10 years, so I am a little concerned and wonder if I should have a CT scan to check it out.
