There can be several explanations regarding these crackling sounds.
1. Your previous lung infection caused changes in the lung parenchyma called "fibrosis". This can
result in stiffening of the alveolar walls and make them less compliant to changes in air pressure.
Pneumonias (lung parenchyma infection) can also result in persistent crackling sounds that may take sometime
to completely heal.
2. If you have asthma, then you can have copious secretions brought about by alveolar and small airway edema.
If the asthma is uncontrolled, then you have these persistent crackling sounds.
3. A condition called bronchiectasis, which results to permanent dilatation of the large airways (brought
about by repeated lung infections) can cause these sounds especially if secretions pool inside the bronchus
during lying down.
4. Persistent infections with other organisms like tuberculosis can also present like this, as well as new
growths or neoplasms in the lung.
I suggest you discuss these closely with your doctors so that you can be properly worked up and managed
Regards and God bless...
