9) Frequent urination and burning pain
Patients with a kidney infection often have an associated bladder infection as well. In these cases, they might have extra urinary symptoms, such as frequent urination and burning pain while urinating. Keep in mind that an isolated kidney infection will not have any of these symptoms. Even if the antibiotic treatment is similar for both conditions, sometimes kidney infections are more dangerous than bladder infections, and we need to make a clear distinction between them both.
Frequent urination results from an irritation in the linings of the urinary bladder. It becomes unable to carry around too much urine and triggers the sensation of going to the bathroom more frequently. Similarly, burning pain while urinating is caused by irritation in the urethra. The urine has some acidity to it, and it would stimulate the pain nerve terminals upon passing through the urethra to be eliminated.
