I am a 19 year old female. I have been having a mucus infection since two years. Early last year, after a sputum culture test, it was found out that I suffer from a Klebsiella infection. I have been receiving Ceftriaxone injections thrice a month for the last six months and in each case, the infection subsides but comes back after two weeks. I am now taking Ciprofloxacin for a week, but still, the infection is present. I do not know what to do.
