Brief Answer:
Get done PFT (Pulmonary Function Test).

Detailed Answer:
Thanks for your question on HCM.
I can understand your situation and problem.
Since your chest x ray and blood reports are normal, possibility of bronchitis is more for chronic cough. I would suggest pulmonary function test after detailed clinical examination of respiratory system. 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 inhaled corticosteroid.

To further discuss the issue, please let me know:
1. Do you have fever?
2. Do you have chest tightness or chest pressure?
3. Do you have dry cough or cough with expectoration?

Awaiting your reply...

Thanks
