What exactly is nausea?

What if you always feel nausea in your head instead of your stomach?

• Whenever I get sick I feel nausea in my head. When I throw up the feeling of nausea is in my head. I'd say about 99% of the times I feel nausea it's in my head. (Only in the absolute worst cases of food poisoning did I feel it in my stomach too.) But when I look it up it says you are supposed to feel it in your stomach. And when I was in the hospital and told them I felt nausea and then told them it was in my head they all looked at me funny. They didn't really believe me until they gave me stomach medications and they helped my head feel better. It isn't dizziness because it isn't a feeling of being light headed or that the world is moving or tilted or that I'm going to faint. It's nothing like that. It's this sick feeling of unease and the feeling that if my brain its own separate stomach it would throw up. It's not just me, my Dad's the same way. So... Could someone help me out with this. I'm wondering how common this is.

• Answer:

  talk to your doctor about it. It's a condition where your nerves are misplacing the signals to other parts of the body..... This is the first time I've heard of it in someone when it comes to illnesses, usually it happens with being able to see sounds, and hear colors and things like that........
