Re: what can you do when allergies make you dizzy?
I suggest finding out what you are allergic to by doing one of two things, either provocation neutralization testing or doing a strict rotation diet which you monitor very closely(harder to do if there are several culprits). I too had many symptoms including debilitating dizziness that was caused by food and mold. I figured out on my own that mold was affecting me but the foods were a real surprise. Since getting my allergies identified I am doing much better and find that all other treatments have a higher success rate.
Hope you get help soon. That is a really tough symptom to have.
