Since almost a year I have been facing this chocking issues. There is a kind of shortness of breath happens which I try overcome by deliberately coughing. Chocking issues leads to "vomit kind of coughing". But vomiting never happens nor any sputum comes out. and by the way I don't have any fever. Two days I did chest x-ray, it came out normal. Almost five months back I did HD Chest Scan, 2D Echo , X-ray chest. All my reports came out normal. I take Montek LC half tablet in the night. I take inhaler as well. But it's not helping. What is my problem ?
