Ok a while back I felt a pain in my chest and I was scared then later that night it got worse and I thought I was dieing it scared me so much. I went to the doctor they said it was stress related.Ever since I have been worried about my health. You know worrying about heart attacks and such. Now since I heard something about a brain tumor I have felt head pains but I also have sinuses and my nose is stuffy right now and my head is hurting with lightheadness and a out of body feeling. It is so scary. My family says there is no way I have a brain tumor but since I am such a flipping hypercondriact I don't believe them. A few weeks ago I got a ekg done which was normal, a xray which was fine, and a blodd test which was normal. Now if I had a brain tumor of anything wrong with my brain wouldn't it of shown up in the blood test those few weeks ago. I mean my blood couldn't of changed that fast from then. Please someone help me I feel so scared. Is this sinus/hypercondria/anxiety or is it something more. I need help please I have no history of brain tumors in the family so there really is no reason I would have one but still with head pains, and a stuffy filling, and lightheadness I can't help but think.
