Thanks for your question on Health Care Magic.
I can understand your concern.
In my opinion, we should rule out lower
respiratory tract infection (LRTI -
pneumonia) and
bronchitis.
Both of these cause fever, cough, expectoration, heaviness in chest and breathing difficulty.
So 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 pneumonia.
PFT is must for the diagnosis of bronchitis.
On the basis of diagnosis, you're will need inhaled bronchodilators, inhaled corticosteroid (ICS) and antibiotic drugs.
Don't worry, you will be alright. First diagnose yourself and then start appropriate treatment.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
