question: i have had sinus problems for years probally 10 plus started after i quit smoking. 3 years ago i had FESS with improvement for only a couple months polyps returned and so did infections. My mos recent infection prompted me to go to the doctor etc.. get leviquin and i didnt work. I had my cousin who works in a lab in a hospital in Pa do a smear culture and start a fungal growth culture, she found heavy growth of e. coli. she directed me back to my doctor wich i had to demand a culture to be done it came back with e. coli and enterobacteracea . It is resistant to most of the antibiotics i can take  im allergic to penicilan oan cephlosporins What can I do?
