I had a CT SCAN December 2012 and MRI March 2013 both came back normal. My neurologist diagnosed it as chronic tension headaches and were prescribe Topamax that I stopped taking about a year ago. I am very scared something is wrong because I am having nagging headaches starting at the back and working its way behind my eyes. I don't know if its anxiety/stress or if its really something wrong. Should I go get another Ct Scan or MRI? My doctor tells me Im ok its from anxiety and sleep apnea. Im just a nervous wreck
