I was diagnosed with pneumonia a couple months ago. And was treated for it. Had a cat scan of chest a month later and it showed normal. However I continue to have chronic wheezing when inhaling and popping or crackling noises in my chest upon exhaling..... I don t necessarily feel bad or run a fever. But cannot get rid of those symptoms...... Pulmonologist doesn t seem that concerned about it..... But feel like there s something going on....,what should I do?
