You’re worrying too much - I’m not a Doctor but shadows can mean anything - infection for instance, or other minor lung problems - following continuous cough etc CT scans showed I had Bronchiectasis - I also have asthma - they are not pleasant medical conditions , but you learn to live with it. Don’t worry too much. It could be showing an infection. Hope someone with more knowledge will give you a better idea
