How Does One Treat For Elevated White Blood Cell Count In The Body?

Hi, I went to urgent care yesterday and the nurse practitioner ran a variety of tests (drew blood, test for influenza, X-ray, urine test). The blood work showed I had an elevated white blood cell count, which the nurse practitioner said is indicative of an infection. The test for influenza came out negative. The x ray was fine. The urine test showed signs of blood but no infection. They sent it in to check for any infection of the liver. Everything negative. But my symptoms were fever(101 F), chills, fatigue, lower body aches, and shortness of breath. The nurse practitioner gave me an iv of rocephin and prescribed me ciprofloxacin. That same night I went home and saw my throat looked like signs of strep throat with the white spots on the tonsils. I also have a persistent pounding headache. I don t know if I should continue and finish off the ciprofloxacin or go back to urgent care to get a different prescription. What should I do? The ciprofloxacin is making me feel nausea and the headache is constant. I was prescribed 500mg 2 pills a day. The reason I was given these antibiotics was because the nurse practitioner believed I had an early onset of a kidney infection (pyelonephritis). I didn t have signs of a sore throat when I first went to urgent care until later that night.
