Not yellow dye #5?: Well, if you didn't accidentally vacuum up a tube of yellow #5 or 23 (Acid Yellow) into your nose then, how bout a sinus infection-- a cold, a flu etc.--sound possible? Headache could be the result of sinus and/or nasal congestion or NEITHER. Do you have bad headaches at other times?
