i think you're asking about symptoms. urinary tract infection (uti) symptoms can include burning when urinating (peeing) frequent urination blood in the urine pain low in the abdomen where the bladder is located and back pain. the only positive way to tell if you have a uti is to get a urine culture performed. this test will tell if there are bacteria in your urine. if there are you will need to take an antibiotic prescription to kill off those bacteria. whenever you receive a prescription for antibiotics (such as penicillin keflex etc. ) you should be sure to take it exactly as prescribed. most importantly be sure to take all the pills even if you start feeling better before you finish the prescription. never "save" antibiotic pills or stop taking them early. this type of behavior contributes to the rise of bacteria that are resistant to antibiotics. wishing you well!
