I am 27/f and I have had a headhache for the last 10 years. I have done cat scans, mri's, been checked for ms and lyme and everything you can think of, all came back negative. I have done all sorts of blood tests. I can get my headaches for 10 days and 1 day it will go away. It can be behind the head, by the temples or the forhead. What in the world is causing these headaches? I mean it's getting ridiculous.
