Eating sour food almost every time will cause dyspnea or asthma. I wonder why.

An ingredient in sour drinks is the allergen of your asthma. I suggest you go to the hospital for an allergen test, which is not expensive. Find out what your allergen is. Your symptoms indicate that bronchitis still exists. I guess it's asthma for the time being. Your asthma can be controlled if you avoid contact with allergens and use drugs to eliminate bronchial inflammation.
