Thanks for your question on Healthcare Magic.
I can understand your concern.
By your history and description, possibility of either
bronchitis or congestive
heart failure is more.
Both these can cause heaviness in chest with breathing difficulty.
So better to
consult doctor and get done
1. Clinical examination of respiratory system
2. Blood pressure monitoring
3. PFT (pulmonary function test) for bronchitis
4. 2d echo (for heart failure).
You may need inhaled treatment if it is bronchitis.
You may need diuretics and other cardiac supportive drugs if it is heart failure.
So don't wait at home, consult doctor, first diagnose yourself and then start appropriate treatment.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
