I'm 20 years old. I have been having headaches for about 4 years. I'm not sure what causes them, I have them everyday from the time I wake and the time I go to bed. I have not slept a full nights sleep in 4 years and if I do sleep its about 2 to 3 hours for a 24 hour period! I have had an MRI and blood tests but they didn't show anything concerning. I was put on a medication for chronic tension headaches, it worked for about a month and a half then it just stopped! I'm at times dizzy and short of breath. I'm having a hard time working and hanging out wuth friends because I'm so exhausted.
