Dear Doctor, I am 30 years old male with sensitive respiratory system which cannot bear Delhi Pollution but have to live here for job. I face short breath mostly in night in these months of year. I was in Nasik for last 4 years and never faced this problem but since I shifted to Delhi 2 years back, I am facing short breath and heavy chest. These days I am coughing like hell with sour throat. Coughing is so strong that I feel like my organs gonna come out of my body and my breathing stops.
