Hello, My wife has been having this problem since more than a year now and it bothers me. She is never able to breathe deep. If she has a deep breathe, then it results in heavy dry coughing for over 5 minutes before she comes back to normal. The cough does not seem like a food choking cough. It sounds more like a cough from the lungs, like when you have bronchitis or similar. Is this anything i should be really worried about?
