I have had Headaches over a year, since December of 2009. I am 16 years old. I take no medications at all. I have been to the doctors. And i have had so many test done. Like, Blood Test, Eye Exam, CAT, MRI, Sinus X-ray, Basic Doctor Exam. My doctor said He has never Heard, Read, or Treated anything like this before. They cannot find a cause. My headaches get so bad I basically scream and cry in pain most times. I get Nauseated, Dizzy, I loss sleep at night, it drains my energy where i do not want to do anything but sleep. I used to could be able to sleep for it to go away but now it don't help at all. I sometimes can't even eat. I actually have one as I am typing this. If anyone knows of a cause please comment and tell me! I don't know what else to do. Thanks!
