Three days ago I hit my elbow hard on the snow falling down while snowboarding. It was swollen and achy. I iced it when I got home and took some Advil. The next day the swelling went down but my forearm and a little bit of my upper arm started to bruise. There was very little pain and I have full range of motion without any pain. On the third day I had a huge black and blue mostly on my forearm and it feels pretty normal except for a slight ache on the actual impact spot. The giant bruise is a little scary but otherwise I feel fine. Should I have this looked at?
