Hi, I slipped on ice and fell very hard on Friday evening. I fell on the point of the elbow and hit my head in two places. My elbow is incredibly swollen, sore and bruise all the way up my arm. I also am noticing some tingling in my hands and fingers. Aswell, at the time of the fall I blacked out for a little bit and was extremely confused, dizzy and had poor balance. I have been suffering a change in my sleeping patterns and today I noticed I was seeing some black spots. My head seems to be bruised/tender. It has been 3 days - is this something that I should be concerned about?
