i, too, have been experiencing the same symptoms of constant headaches, nausea (like morning sickness or hang-over) and blurred vision and loss of appetite. I've had my eyes checked and they're perfectly fine, took a pregnancy and I'm not pregnant. I rarely ever get sick and the only thing different that I can recall doing is getting the FLU shot because I've never gotten it before. I keep thinking that it will go away but it doesn't. Oh yeah!! Another thing I have is that I feel as though my ears are clogged like when water gets inside of them, but the Dr. said my ears were fine too. I understand that it may be hard to put a presice diagnose, but I need something to suggest to my DR. just in case....can you help??
