How can you know if you have a urinary tract infection?

Urinalysis & culture: Will show whether you have a uti. Uti can be suspected from symptoms of frequent urination, burning sensation or pain on urination, back pain or blood in urine.

Kidney infection: Kidney infection (pyelonephritis) generally causes fever, chills and very significant flank pain. One generally feels "sick". Bladder infection (cystitis) rarely causes systemic symptoms. Discomfort in the pelvic area and irritative voiding symptoms are typical.

UTI: The surest way to know if you have a urinary tract infection is to have your urine checked. There are urine dipsticks that can detect infection. The symptoms of a UTI can include painful urination, feeling like you have to urinate often, but only passing a very small amount of urine, and urgently feeling like you have to urinate. It can get worse from there.
