hello I just need some insight. Ive been having headaches for a while, they really only hurt if I shake my head left to right. ive also had some sinus isues as well though. But I also get deja vu and a lot of the time I just feel spacey and out of it, my doctor said I was fine. but I looked upp symptoms and according to google, all signs point to a brain tumor. I also remember my father had a brain tumor at my age. does this sound like a possibility? if I take excedrine migraine I feel fine for a couple of days,but then its back through the same thing a again. its been like this for 4 months, im just worried its a brain tumor, I have no visual problems tho other than floaters. so what im trying to say is, do I have a brian tumor?
