     Now here's the problem......I get bad headaches real bad over over my left temple (where my tumor was,  it was shrunken by chemo and radiation) and I passout. Some of the passing out comes with dizziness, once in a while nausea, no vomiting.  I have gone to the ER with these headaches they did an EKG....normal. Also a CT of my brain without contrast.....normal(sinuses normal too.) The headaches hurt worse when I bend forward. I had the CT last week.......
