I dropped a wooden clipboard (with the metal part on top) onto my foot (accidentally of course) yesterday evening, at first there was a very blue bruise but it was small and Idk if it was swollen, and the shock from dropping it went on for 10-15 min. (thats pretty long) so I just rested it and watched a show, then went to sleep. This morning I was sitting on the floor to get something and the top of my foot touched the floor, and the pain was excruciating. And whenever, I walk on it, It feels uncomfortable, just like a little feeling. Oh, and the pain I was describing would be classified as a stinging pain when I touch it or if it touches anything. Sitting down, the uncomfortable feeling is there. Now my foot is swollen not too much though and the bruise is a bit larger and its less blue. Is this serious, did I break something or.... (also I am 12 so that's why it was under children's health)
