Hello. I was in a car accident yesterday and visited the emergency room immediately after. I was told that I suffered a minor concussion, nothing to be too concerned about. However, this morning when I woke up, I noticed a large knot underneath the center of my chin. While I am not in any severe pain, the knot is tender to the touch. Please help me make sense of this new injury--should i be alarmed and return to the emergency room?
