Kidney Infection

A Kidney infection is a painful and unpleasant illness caused by bacteria travelling from your bladder into one or both of your kidneys.


Common symptoms include:

  • Pain and discomfort in your side, lower back or around your genitals.
  • High temperature.
  • Shivering or chills.
  • Feeling very weak or tired.
  • Loss of appetite.
  • Feeling sick or being sick.
  • Diarrhoea.

When to see your GP:

We advise you to come and see your GP if you have a fever and persistent tummy, lower back or genital pain, OR if you notice a change to your usual pattern of urination.

Most kidney infections need prompt treatment with antibiotics to stop the infection from damaging the kidneys or spreading to the bloodstream. You may also need painkillers.
