A 40-year-old man comes to see his General Practitioner with sudden onset of severe right flank pain that radiates to his groin and vomiting. He has no medical history. During examination, his heart rate is 90 beats per minute, blood pressure is 129/79 mmHg, and temperature is 36.5 °C. He is well hydrated. A urine dipstick shows microscopic haematuria but nothing else. The doctor suspects renal colic. What is the most appropriate initial management option for this patient?
