How long does it take for a urinary tract infection to turn to a kidney infection?
I’ve been showing symptoms for about two days now but normally my drs surgery is very busy and at times j have to wait like a week for an appointment? So how long does it take to progress into a kidney infection?

Can be as quick as 2-3 days for sure, you need to get that treated ASAP. if you don’t its gonna hurt like Hell. like your kidneys are filled with tabasco sauce.
