I have allergies - pollen, mold. I live in Southern florida - so yes more often than not i have fluid my sinus, but this is the norm for the season for me. Yes, i become dizzy. No headache. No nausea-vomiting. It only happens when i am upright or walking. Triggered sometimes but not always if i am in an elevator or navigating an incline. I don't monitor my blood pressure, but have never been told it was an issue for me when measured. I'm 5'4 and weigh about 140. Its been about the last 3 months. To eliminate another variable - i drank no alcohol for a weeks at a time and it still occurs (normally a moderate to heavy drinker)
Well the whole idea behind writing a website at 2 in the morning on Friday night to get advice on a medical problem is that i am not the type of fellow who has the means to procure the services of a "regular doctor", but I will research your suggestions and appreciate your determination of urgency. Thank you for your time.
