I have had frequent headaches that no medicine seems to quiet. Also, I am exhausted most of the time and feel light headed and dizzy. I have been to the dr on 3 seperate occasions, and each time, the tests showed nothing wrong with me. I had a CT scan and a neck xray, but no blood tests, or MRI. Of course, the dr keeps looking into my eyes with his little light thing....so I assume that I do not have a tumor. There are days that go by when I feel 100% normal, and other days when the symptoms grow worse and knock me down for a few days. Does anyone have a clue? I am a 32 year old woman, have 2 kids, a great job, and am NOT depressed.
