Lung Crackling

[msmitty]

So I am currently experiencing crackling in my lungs. This will happen infrequently - about once every two weeks, but for a few hours or a whole day. When I breathe in it sounds like my lung is crackling. I had a collapsed lung about 6 months ago, and I have pain all over my chest, which I figured was from the lung surgery - but the crackling is strange. It is mainly on the side which had no collapsed lung, but sometimes in both. Thoughts?

yes, it hurts in the upper back on that side as well. not all the time but pretty often...
