[|Human|] I am a 21 year old female. I have been smoking for 4 years and I have never had any respiratory issues until this week. Everytime I take a deep breath, it feels as though I am gasping for air. I went to my Doctor and my O2 level came back at 100%. My blood pressure was normal for my age and weight. I have been having slight discomfort on the left side of my chest which did worry me but it is not unbareable. I have not been smoking for the past 2 days because my sister (who works in a respiratory department in a hospital) said I could have something they call a "cloudy lung" because of the smoking. How long would a cloudy lung take to clear? And is that what it could be?
[|AI|]  Hello dear, welcome to Chat Doctor.come have gone through your concern in depth.* The cloudy lung indicates different types of conditions as - lung emphysema - effusion or pneumonia - severe pulmonary congestion - tumor - tuberculosis - others.* Needs x-ray of chest to find out the diagnosis and get management in accordance with that rather than getting panic.* And just stick to the decision of not to smoke now in future for your better health aspects. Wishing you fine health ahead. Welcome for any further guidance. Regards.
