Thanks for your question on Healthcare Magic.
I can understand your concern.
At present, he is taking treatment for
bronchitis.
Since he is not improving with this treatment, we should definitely look for other causes for his symptoms.
In my opinion, possibility of
pneumonia is more.
All his symptoms like coughing,
shortness of breath,
tiredness, weakness etc are commonly seen in pneumonia.
So better to
consult pulmonologist and get done clinical examination of respiratory system and chest x ray.
Chest x ray is must for the diagnosis of pneumonia.
He may need higher antibiotic, antihistamine and anti inflammatory drugs.
Don't worry, he will be alright. First diagnose himself and then start appropriate treatment.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
