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.
