I understand your concern.
I am Dr. Arun Tank, infectious dissensitivityialist, answering your query.
In my opinion you should start with antibiotics like cefixime
under your doctors guidance.
Also take the sputum out and sent it to the doctors for culture and sensitivity.
Thereafter switch the antibiotics to the newer sensitive antibiotics.
Taking the full course frees you from the infections.
Please do respiratory exercise also, it will help you clear up the infections early.
I will be happy to answer your further concern, you can ask me on bit.ly/DrArun.
