A Kidney Infection Does Not Require Earlier Cystitis
Bladder & Pelvic FloorArticleA previous bladder infection is not a requirement for a kidney infection. Have concerning symptoms assessed.

If you suspect a kidney infection, get urgent medical advice for fever or shivering, pain in the lower tummy or back just under the ribs, blood in your urine, vomiting, no urine all day, or pregnancy. In England, contact your GP urgently or NHS1 111; elsewhere, use local urgent care.1
Myth: a bladder infection must happen first
NHS1 guidance says a kidney infection is often caused by cystitis, but it can also occur without cystitis. Not having noticed an earlier bladder infection does not rule it out.1
Describe what is happening now
A clinician needs to assess the current symptoms. Tell them where you have pain, whether you feel sick or shivery, and any changes in urination. Those observations are information for assessment, rather than a way to diagnose yourself.1
Laugh, Sneeze, Jump includes an appointment prep sheet. Use it to organize questions for your clinician; getting care comes first. See the book.
