Hi, it is so nice to have you to contact! I have had what 3 doctors have told me is bronchitis for 2 to 3 months each time last year. 3 rounds of different antibiotics didn’t resolve it. My internal medicine Dr. sent me to a Pulmonologist, Cardiologist, and ENT doctors couldn’t find the problems after several tests. The sysmptoms of wheezing on shallow breaths, on deep exhale “snap, crackle, and pop” as one doctor put it, shortness of breath, and a cough which is sometimes very low in the chest keep recurring. Would you have any idea of what this may be or what other type of physician I should see? Any feedback would be much appreciated!
