I went to the ER 2 weeks ago. Dr thought I had kidney stones because of severe pain and blood in my urine. CT scan was clear so after test he said I have a kidney infection. Sent me home with Cipro, lortab and nausea meds. Now 2 weeks later after taking the meds I'm having the same pain but worse in the area. Could the infection be back or could it be something else. I'm confused and not sure if I should go back to the ER. I don't have a primary dr because of just moving to this state. Could it be a stone the CT scan missed. Why 2 weeks later am i still in so much pain. Any advice appreciated.
