Pseudomonas putida

Hello all - I have had recurrent sinus infections for decades. Finally in 2020 it was discovered that I had fungal sinusitis so I underwent surgery. It didn't eradicate everything so in 2022, I underwent surgery again. I recently developed another sinus infection and my primary doctor thought it was a good idea to get a culture done, just in case. Here are the results:
Acinetobacter johnsonii - moderate growth
Staphylococcus capitis - Scant growth
Pseudomonas putida -Scant growth
I have just started a sinus rinse of Gentamicin but am worried that this will never go away and am concerned about what the potential is for this becoming more dangerous. I have been taking immunosuppressive drugs for MS for the past 7 years but stopped 3 months ago. Will the fact that I am no longer taking that medication make it more likely that I can get rid of this with the rinses?
Thank you in advance.
