I'm 56 5'5" 200 pounds. I am on medication for low thyroid, high blood pressure and high cholesterol. The last couple days I get light headed if I look up. Normal activity is ok, walking doing things around the house but when I look up I get that inbalanced feeling. Everyone around me is complaining of allergies, I've been put on Allegra diferent times for my ears being full of fluid. Could this be allergy related? My ears don't seem clogged but they do make buzzing noises when everything is quiet.
