Thanks for your question on Healthcare Magic.
I can understand your concern.
In my opinion, you are mostly having post infectious
bronchitis. It is common after pneumonia. And it is more likely when you are having underlying pulmonary disease like primary pulmonary
hypertension (PPH).
So get done PFT (pulmonary function test).
PFT will not only diagnose bronchitis but it will also tell you about severity of the disease and treatment of bronchitis is based on severity only.
You may need inhaled
bronchodilator and inhaled
corticosteroids.
At the same time control of PPH is also needed.
Available drugs for PPH are
sildenafil, tadalafil, bosentan, ambrisentan etc. You should start any of these drugs after consulting pulmonologist.
Don't worry, with appropriate treatment, you will be alright.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
