<s>[INST] Hi, I had pneumonia about five years ago. I got recovered after taking the antibiotic medicine. About a month ago, I had physical check up, the doctor found the scar in my lung he suggested further visits. I noticed myself too when I run, I feel out of breaths at the beginning but get better later on. Some days, I feel out of breaths not doing any exercises. My question is, could this symptom caused from the pneumonia that I had a while ago? Thanks. [/INST] Yes it may b related to ur old lung problem. ...better to visit some good pulmonologist...since old pneumonia could have damaged ur lung or this might be newer pathology. ....get xray done and also consider tuberculosis if u hav any family history </s>
