My hayfever is so bad, I can't go outside.

Hi, I was just wondering if this dizziness is a sign of allergies? I developed an allergy to milk last year ( I actually think I've had a minor form of it for a while but it got much more severe last year) and I started feeling ill all the time and as well as an upset stomach I used to feel dizzy and sickly. Then whenever I eat something now with milk in (I try to stay away from it but some foods contain traces and it doesn't always make it clear so I just have to try things and then rule them out) I get this dizzy feeling back and I'm wondering if it's like a drop in blood pressure that can be caused by allergies or something. Sorry to ask you as you probably get LOADS of medical questions but my doctor wouldn't listen so I need information before going back and making her listen...

Also sorry for bursting in on this thread, interestingly I also have hayfever and when I was younger I used to get terrible rashes EVERYWHERE but now I don't although I get the odd small outbreak. My other symptoms have been worse than ever this year up to now though.
