I was wondering if you could give me some idea of what i can do to ease the discomfort of excess mucus buildup in my nose and throat after eating all foods. All day I am having to clear my nose and throat I am also coughing up mucus that has collected in my chest. I am assuming it is an allergic reaction to all foods eaten but it is very worrisome. I have had food allergy tests done but nothing show up. Any ideas would be welcome. Thank you.
