Hi again, Complications - I am sorry that you didn't find anything of value within the article I shared.
You may be aware, we cannot provide medical advice or diagnostics over the internet (for your own safety), but your concerns certainly warrant further attention.
You may be interested in learning more about lung breath sounds. When it comes to crackles, what a patient describes (as crackling), compared to what a physician hears (as crackles), can be different. Perhaps this article (from the National Institute of Health), will provide you with additional information: https://www.ncbi.nlm.nih.gov/books/NBK537253/#:~:text=Crackles%20are%20generated%20by%20small,deeper%20pitched%2C%20courser%20crackles).
It must be somewhat frustrating for you to hear the lung sounds you described but the physician cannot. This also may be something you'll want to continue to discuss with the doctor. Between you and him, you should be able to determine what, if anything, should be done next.
Wishing you well,
