A kidney infection
, or pyelonephritis, is a bacterial infection. The infection usually starts in your bladder or urethra and moves into your kidney. One or both kidneys may be infected.
Common signs and symptoms include the following:
- Pain in your abdomen, lower back, or sides
- Pain or burning when you urinate
- A sudden strong urge to urinate or urinating more often than usual
- Cloudy or bloody urine
- Fever, chills, and fatigue
- Nausea and vomiting
Seek care immediately if:
- You have a fever and chills.
- You cannot stop vomiting.
- You have severe pain in your abdomen, lower back, or sides.
Contact your healthcare provider if:
- You continue to have a fever after you take antibiotics for 3 days.
- You have pain when you urinate, even after treatment.
- Your signs and symptoms return.
- You have questions or concerns about your condition or care.
- Antibiotics treat your bacterial infection.
- Acetaminophen decreases pain and fever. It is available without a doctor's order. Ask how much to take and how often to take it. Follow directions. Read the labels of all other medicines you are using to see if they also contain acetaminophen, or ask your doctor or pharmacist. Acetaminophen can cause liver damage if not taken correctly. Do not use more than 4 grams (4,000 milligrams) total of acetaminophen in one day.
- NSAIDs , such as ibuprofen, help decrease swelling, pain, and fever. This medicine is available with or without a doctor's order. NSAIDs can cause stomach bleeding or kidney problems in certain people. If you take blood thinner medicine, always ask if NSAIDs are safe for you. Always read the medicine label and follow directions. Do not give these medicines to children under 6 months of age without direction from your child's healthcare provider.
- Prescription pain medicine may be given. Ask how to take this medicine safely.
- Surgery may be needed if a ureter is blocked. The ureter is the tube that takes urine from a kidney to the bladder. A blocked ureter can cause repeated kidney infections.
Drink liquids as directed:
You may need to drink extra liquids to help flush your kidneys and urinary system. Water is the best liquid to drink. Ask your healthcare provider how much liquid to drink each day and which liquids are best for you.
Urinate as soon as you feel the urge:
This will help flush bacteria from your urinary system. Do not wait or hold your urine for too long.
Clean your genital area every day with soap and water:
Wipe from front to back after you urinate or have a bowel movement. Wear cotton underwear. Fabrics such as nylon and polyester can stay damp. This can increase your risk for infection. Urinate within 15 minutes after you have sex.
Follow up with your healthcare provider as directed:
Write down your questions so you remember to ask them during your visits.
