I cough up mucus several hours after eating, may last 30 mintues and then I am fine, I have some allergies to food products, could this be the cause? I had to start taking an acid med before eating to help with the reflux it was causing.Sometimes I get this bad taste when coughing, this has been happening for 3 years now. I had bronchitis in 2006 really bad, and ever since i have had a problem. I have been to the dr many times to get steriod shots, took all types of test, and now i am better, but still have the coughing sometime later after eating, is it the food? What my allergies are in food is everything I eat almost.What do you suggest I do?
