Thanks for your question on HCM.
I can understand your situation and problem.
By your history and description, I think you are having
bronchitis.
The most common cause for this is
lung infection.
So I advice you to
consult pulmonologist and get done
1. Clinical examination of respiratory system
2. Chest
x ray 3. PFT (Pulmonary Function Test).
Chest x ray is needed to rule out lung infection.
PFT is needed to rule out bronchitis.
It will also tell you about severity of the disease.
And treatment of bronchitis is based on severity only.
So get done PFT.
You may need inhaled bronchodilators, antihistamines and antibiotic drugs.
So better to consult pulmonologist and first diagnose yourself and then start appropriate treatment.
