Hello dear, thanks for your question on HCM.
I can understand your situation and problem.
Breathing difficulty after
pneumonia episode can be due to post infectious
bronchitis.
Actually healing after pneumonia, causes structural and morphological changes in lung.
So these can cause bronchitis after pneumonia and can lead to breathing difficulty.
Better 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 pneumonia recurrence.
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.
So consult pulmonologist and discuss all these.
