Does it take along time to heal from a kidney infection?

Depends: A simple UTI usually takes a few days to get better with the right antibiotic. A kidney infection is more serious as it higher up in the urinary tract. The times it takes to heal depends on the severity of the infection and the type of organism it is(some more aggressive). It also depends on how strong your immune system is at fighting the infection.Your doctor can tell you more info!
