Dear friend, welcome to HCM.
the pain is obviously due to UTI/ cystitis
pl. see if the klebsiella was not ESBL class, which is usually resistant one. was it sensitive to amikacin?
what are your other reports saying?
could you pl. post them , so that i will get a better idea about your proble.
sometimes culture may not grow bugs , even if infection persists. did you have an ultrasound
, bladdder/ MRI mentioned it?
in consultation of your treating doctor,pl. take urinary analgesics like phenazopyridine
, urinary alkalinizers, consider prolonged or changed antibiotic regime according to culture.
a detailed description, age , other medical problems, reports etc , will help if posted online.
take care and keep me posted on the progress.
I would be glad to assist.
