where does it hurt when you have a kidney infection
A kidney infection usually hurts in your side or back , just under your ribs, rather than low in the front like typical bladder pain.
Where the pain usually is
- Most people feel pain:
- In the flank (side of your back) below the rib cage, on one or both sides.
* Near the middle of the back, just to the left or right of the spine.
- The pain can:
- Stay in that back/side area or radiate toward the lower belly or groin.
* Be worse if someone presses over the kidney area or when you move.
A lot of people first think it’s “back pain,” but the location is higher than typical low-back strain and often more to one side.
What the pain feels like
- Often a dull, deep ache or throbbing pain in the side or back.
- It can become sharp or more intense, especially with movement or touch.
- It may come with:
- Fever and chills.
* Nausea or vomiting.
* Burning when peeing, needing to pee a lot, or cloudy/dark or smelly urine.
