Hello dear, thanks for your question on HCM.
I can understand your situation and problem.
In my opinion you should
consult pulmonologist and get done
1. Clinical examination of respiratory system.
2. Chest x ray
3. PFT (Pulmonary Function Test).
By your symptoms and history, possibility of
asthma or
bronchitis is high.
Chest x ray is needed to rule out
lung infection and
lung cancer.
PFT is needed for the diagnosis of asthma or bronchitis.
It will also tell you about severity of the disease.
And treatment is based on severity only.
So get done PFT.
You may need inhaled bronchodilators and antihistamines drugs.
Don't worry, you will be alright.
Consult pulmonologist and first diagnose yourself and then start appropriate treatment.
