Hello and Welcome to 'Ask A Doctor' service...
I've gone through your query in details...
I can understand your concern...
Well, it seems like you've been through a lot already!! It's good that there was no pneumonia.
Coming directly to your query: Yes, they do stay in our system (although duration can vary, it's generally for up to 3-5days) even after completion of the full course.
Since it's recurring despite the antibiotics therapy so often, I'd also consider getting a few more investigations done for further evaluation. Namely, a complete Hemogram with ESR, Sputum gram stain, AFB, fungal stain as well as Culture sensitivity assay and a CT-PNS(Paranasal sinus).
All these will clarify things further as to establish the diagnosis also. Sinusitis can be secondary to numerous pathogens (the offending bug could already be resistant to these antibiotics, so a detailed evaluation should be carried out).
Please discuss these with your doctor and proceed further.
Additionally, please refrain from having any cold beverages, extreme sour foods as they can further worsen the symptoms. Avoid going to any dusty/overcrowded places for the time being.
Take steam inhalation thrice daily. Always ensure to wash your hands with antibacterial hand-wash before and after handling the respiratory secretions, sputum etc. Do wear face masks whenever going outside.
Have plenty of hot beverages (soups, broths, hot menta tea) as they'll work as an immunity booster.
Let me know if I can assist you further.
Take Care
Kind Regards
