Hello, thanks for using health care magic Its a good thing that your x-rays did not show any fracture. However, fractures are not the only injury that one can sustained following a road traffic accident. Other injuries include contusion of body parts, stain of ligaments or tendons etc all of which could cause local inflammation that require a couple of days or weeks to resolve. Most importantly, you should have a rest and avoid straining the body parts that are affected so the inflammation should reduce. The pain you felt should be of decreasing intensity if not it will imply there is an underlying severe condition such as non diagnosed fracture, or tendon rupture etc and you will need to be re-examined. There are just two things you need provided there are no underlying problems; rest and pain killers. However, the choice of pain killers matters depending on the severity of your pains and if you have ulcer disease. Hope this helps you Best regards Dr Achuo
