question: i went to the er with terrible back pain (i suffer with problems with my sciatica) and pain in my groin area felt like shooting pain. Drs. did a dipstick urinalysis and foud my urine was cloudy, small amounts of blood,4.0 urobiligen, specific gravity of 1.013,ph of 6, negative for glucose,bilirubin,ketones,protein and nitrates. wbc 5-9,rbc 1-4,trace of esterase and many bacteria. they think its a uti so they started me on ceftinir but now im having terrible headaches, i have been taking medicine every four hours but it keeps coming back could this be a symptom of my uti
