I went to hospital Wednesday after shaking profusely an vomiting.  I was immediately taken in to the emergency room hooked to an IV and told I passed a kidney stone, I was then was sent home only to wake up the next morning shaking and vomiting again and was taken by ambulance again to the emergency room and spent a couple of days in the hospital and was given a prescription  for of levofloxacin 500 mgs. I am also going to make an appointment with a urologist after I finis my meds. What I want to know is what causes kidney stones and I must have passed a  more than one. Is it possible to pass more than one?
Welcome to the forum. You might be having a combination of stones and infection, called urosepsis. Only this can cause such severe - fever, chills and vomiting. You need evaluation by urine tests, bloods and CT SCAN. Antibitocs will take care of infection and stones need to be treated based on location and size. FYI, any number of stones can be passed out in urine, Best regards
