yes, your mom would be hurt if she did not know. It is most likely
an infection and a doctor can tell just with a urine sample and
you may not even need a scan. Most of the time the things we
worry about aren't as big as we think they are!
However a kidney infection ignored can make your petty sick and
cost your mom more worry and heartache in the long run!

im not an expert, but assuming that you are a brit and on the NHS, i dont think so. but im sure your mum would rather know than not. you should tell her and get it sorted right away!
