Hello, Dr. Rynne My name is Liz. I ve been experiencing a persistent feeling of tightness in my lungs/bronchial tubes for a couple of weeks. I have asthma, and this feeling is much like the early warning sign of an asthma attack, but I haven t had one, even though I ve been exercising. Use of my inhaler (admittedly an old, out of date one) has not helped. I live in Asia, which is why I haven t just gone to a doctor. My experience here is that they tend to throw antibiotics at everything.
