Hopefully, if it was a stone, you have passed it by now. And, hopefully, if the pain persisted, you went to a doctor. Fever is not a frequent symptom. And, pain when urinating, more often occurs when the stone has moved into the urinary tract. Pain in the back, in the region of a kidney, & blood in urine are the top symptoms. You may be able to see the blood, or, the amount my be small, but the doctor can test for it. Keep in mind, some types of stones grow rapidly & large, and cannot be passed. These require a visit to the hospital.
