I am seeing the Dr. in 3 hours. I have been having headaches every day. Same spot in back lower left side. It seems like it gets worse when I lay down. I will wake up at night and it hurts so bad sometimes it keeps me awake or I'll have to get up and take something. To go along with this, I hear my pulse/ heartbeat in my left ear all the time. Of course I'm thinking this is it and I have a brain tumor. I did a search ( I know...BAD ) and I read that headaches when laying down is classic brain tumor symptom. I barely slept at all last night because of this. I am shaking, nauseated, dizzy and on the verge of tears. What else could be wrong with me? Why does my head hurt so much in the same area? I'm trying to prepare myself for the worst, hoping for the best. What else can I do? SO many times I've gone to the Dr. for something and I feel like I've dodged a bullet. I'm constantly thinking WHEN? I REALLY feel like THIS time something is really wrong. If not...I need serious therapy. I can't live like this anymore. I feel like I'm waiting to die. This is my second post here, other than my introduction. I don't know any of you, but, if you're reading this and you wouldn't mind, could you send some good thoughts my way? I have so much to look forward to this summer. I can't be sick!
