Hi and regards from our team.
I've gone through you case and understand your concern. I will require more information to give you a better opinion.
Please would you be able to provide me with details of the lab investigations or a chest x ray?
Can you tell me what medicines he was on, the dose and duration of the same?
If I get the two answers, I can come to a diagnosis of what he is ailing from, and why the first therapy was ineffective.
Please reply so that we may help you better.
Dr. Jacob George P
