Thanks for your question on Healthcare Magic. 
I can understand your concern. 
By your history and description, we should definitely rule out heart (congestive cardiac failure) and lung (acute 
bronchitis) related diseases. 
So better to 
consult doctor and get done ecg, 2d echo, chest 
x ray and PFT (Pulmonary Function Test). 
Ecg and 2d echo are needed for 
heart failure. Chest x ray and PFT are needed for bronchitis. 
You may need antibiotic, diuretics, bronchodilators and other supportive drugs on the basis of diagnosis. 
Don't worry, you will be alright with appropriate treatment. 
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
