Can you have a kidney infection without obvious signs of a UTI or fever?

Can you have a kidney infection without obvious signs of a UTI or fever?

Yes and No: Uti is an infection anywhere in the urinary tract and is verified by a positive culture. Most utis involve only the bladder/urethra (aka cystitis: urgency, frequency, burning). A more severe infection results when a UTI progresses to involve the kidneys/ureters (aka pyelonephritis: fever, chills, n/v, back pain, sick). Pyelo may or may not be associated with or preceded by cystitis symptoms.

Is there always a fever when you have a kidney infection. And can the infection make you feelin unusually weak with zero energy?

Is there always a fever when you have a kidney infection. And can the infection make you feelin unusually weak with zero energy?

No and yes: Urinary tract infections typically present with increased urination, discomfort with urination and abdominal pressure. Other symptoms can be flu - like symptoms/fatigue. If the infection ascends up the urinary tract, kidneys can become infected and cause high fever and serious illness. So in summary there can be a spectrum of disease, fever is not always present.

Been on nitrourantoin for a bladder/kidney infection for 4 days still got back pain and fever & flu symptoms when will I get better?

Been on nitrourantoin for a bladder/kidney infection for 4 days still got back pain and fever & flu symptoms when will I get better?

Might need ABX chang: If you have not seen an improvement in 4 days, you might want to check back with your physician. It could be the bladder infection is not sensitive to that antibiotic or maybe there is something else causing the pain that you thought was a bladder infection. Additionally, Nitrofurantoin is a great medication but does not have the coverage of bacteria that other bladder antibiotics have.

I've been experiencing sharp pain (left side) back pain. Fever&vomiting. Its been three days&it just gets worse. What is this im feeling? Kidney infection

Definitely possible: It sounds like an infection that is either climbing or made its way to your kidney, called pyelonephritis. This can often occur from an untreated, sometimes subclinical urinary tract infection. This can be dangerous and I would recommend seeing a physician as soon as possible as left untreated it can cause kidney damage or systemic infection leading to even more serious problems. Please see someon.

Unlikely: It is unlikely to get UTIs and kidney infections without symptoms however your dr would have based the diagnosis on your urine tests which is the most definite way of diagnosing a kidney infection

Can kidney infections go away on their own? I think I have 1 because of back pain nausea flu symtoms fever pain when I pee. Don't want 2 go 2 docs.

Must go to doctor: No kidney infections can be life threatening in young women because of acute kideny infections, pylenophritis can sepsis shock and organ faillure. Back pain may suggest acute pyelonephritis if associated with high fever, chills or rigors. Need to see a doctor to do urine culture, antibiotic therapy, and to make sure there is no obstructive pathology like kidney stones. Hence, must see a doctor.
