I am 31 years old men and my weight and height is 82, 5" 9. I am troubling with the breathing difficulty from last week and mostly when I am lying on bed. I have some allergies with dust and smell. Like painting, petrol, old dust. I have done the blood test but no issue found there. So please suggest what test has to be done for the same. Kindly suggest thanks in advance. Please tell me, It could be case of cholesterols. If yes so what test would be the same. Thanks
