I do have a smell allergy like any type of smoke, cigar smoke, cooking fumes, perfumes, excessive body spray all triggers me terrible cough. However I also have a cough while eating food eg. Wheat bread, any candies, chocolates, peanut, etc, I can not even have one spicy chilly bite, I will have terrible cough episode and even shake my body and fall down. I have to drink some type of yogurt milk to soothe down right after eating every bite. Till it settles down. Please help me to cure the problem. I am 38, working I hate to cough at work. Due to coffee smell, someone perfume smell, someone cigar smokers crossing by me. Passive smoking may have created this terrible allergy to me. Any fruitful response appreciated. I was initially diagnosed with acid reflux but no luck. Problem is still there for more than 5 yrs.
