Sinusitis and Klebsiella penumoniae

Hey everyone, I really need your help, I think I’m going crazy lol

I've been dealing with a really bad smell in my nose for about six months now. I'm not sure how to describe it, but it's this kind of sour, rotten smell that just won't go away. Whenever I bend over or tilt my head down, the smell gets much stronger.

An ENT doctor diagnosed me with sinusitis, and a nasal culture showed that I have Klebsiella pneumoniae bacteria. I’ve tried three different types of antibiotics – Augmentin, Zinnat, and Cipro – but none of them have helped. They’ve also given me different nasal sprays, and they haven’t worked either. However, another doctor I saw completely disagreed with the first one and said that the antibiotics should have worked, so the smell probably isn’t related to the bacteria, which honestly left me even more confused.

Has anyone experienced something similar? This smell is honestly unbearable..

Thanks a lot!
