Question: My kid just woke up with a stinging sensation on his head, he pointed to it and there is a visible dent and skin color difference where he is pointing. He sleeps on a bottom bunt, and there is a possibility in my mind he was laying sideways and had his head against the wood. I'm just worried about concussion possibly from something I'm not thinking about. He has sleep walked once in the past, but we were up and should have heard something. My wife is just wondering if his skull still isn't fused there or it is naturally that way for his head, I don't buy that however because he pointed right to the dent and said it was stinging there and the color of the skin on the dent is a different color... like if you smashed your fingers in a wench and the skin color changes. He says now it is hot feeling there.
