Thanks for your question on HCM.
I can understand your situation and problem.
By your history and description, in my opinion you are having post infectious bronchitis
. Lung infection
causes inflammation and some morphological changes in lungs. Due to these, some patients develop bronchitis.
Your symptoms like breathlessness, wheezing
and phlegm are suggestive of bronchitis.
So consult pulmonologist
and get done
1. Clinical examination of respiratory system
2. PFT (Pulmonary Function Test).
PFT is needed for the diagnosis of bronchitis. It will also tell you about severity of the disease. And treatment of bronchitis is based on severity only.
You may need inhaled bronchodilators and antihistamines.
And yes, get done 2d echo for enlarged heart
on chest x ray.
