After a bronchoscopy in February of 2013, my doctor said some secretions/no infection. I had to have another in March of 2013 and he told me I have bronchomalacia and there is no treatment/no cure, to continue my updrafts (which don't seem to help), and said that he didn't recommend stents, they wouldn't be of help. Could bronchomalacia have developed this quickly? I seem to be getting worse with more shortness of breath.
