I get a head cold, (FLU) sinus dripping, cough, eyewatering, sneezing, body aches, upset stomache, cold and hot, and body hurts to touch, no desire to eat. After 4 days, I am eating and everything seems to have intensified flavor. I also seem to have bad breath no matter what I do. I m thinking bad breath due to sinus - but the heightened sense of taste?
