I'm an 18 yo female. I have a history of anxiety diagnosed two years ago that caused chest pain, heart pain, dizziness, feelings of passing out, tingling in hands and feet, shortness of breath, and heart palpitations. I was put on lexapro and wellbutrin. They helped for a little while, but lexapro made me extremely tired. I came down on both lexapro and wellbutrin about a month and a half ago and have been on prozac for the past week. For the past month i have been having horrible headaches on the left side of my head. For about the past two weeks or so i have had some pain on the right side as well. With these headaches i have a lot of naseau, no vomitting though. I have been gagging for the past 4 months. Its pretty weird. It happened alot when i was eating out, also when i am walking outside in the heat. Or if i overeat and have gas. This is interfering with my daily life. The dr says its anxiety but i'm not convinced? Is something wrong with my head? Also i passed out in april 09 coming out of the shower and hit my head on the wall and floor i had a CT of my head and everything was fine..mild concussion. I've also had pretty bad dizziness. To the point where my vision blacks out and i can't see. Please help!
