Hi, I Have Suddenly Gotten A Massive Headache At The

Hi, I have suddenly gotten a massive headache at the back of my head, it came on so suddenly that I thought that I was hit with a baseball bat. It is the worst headache I have had in years and I am barely able to type this right now due to the pain. I am 45 years old and my Mom and Dad have both had aneurysms and i'm really worried. I think I'll just sleep it off.
