Thanks for your question on Health Care Magic.
I can understand your concern.
Since you had
pneumonia, we should first rule out relapse of pneumonia as a cause for your
chest pain.
So first get done chest
x ray.
If chest x ray is improving than no need to worry for pneumonia. Post infectious
bronchitis can cause similar kind of pain.
So get done PFT (Pulmonary Function Test) for the diagnosis of bronchitis.
Mucolytic, expectorant and antioxidants drugs are useful in your case.
Inhaled bronchodilators and inhaled corticosteroid (ICS) are also needed.
So better to first diagnose yourself, get done chest x ray and PFT, than start appropriate treatment.
Hope I have solved your query.
Wish you good health. Thanks.
