Bruising, Swelling In Wrist After Falling From Bike. X-ray Normal. Hurts On Rotating Wrist. What Does It Indicate?

Hi, last tuesday i fell off my bike and fell onto my left hand when it was outstretched and had bruising and swelling in the wrist on the ulnar side later that evening. the first chance i got to go to the hospital to get it xrayed was on friday, and it was the fastest trip ever, i was in and out in an hour. the doctor barely looked at my wrist, and didn t touch it, but sent me for xrays. they apparently looked normal, and said it was probably sprained or something , but he decided to give me a splint for the long weekend for support. on monday night i stopped using the splint, but my wrist is still a little swollen and quite sore. it is now tuesday evening, and it hurts when i rotate my wrist or bend it, and when i move my pinky away from my ring finger, even when wrapped with a tensor. Could the doctor have been wrong about my injury? what should i do?
