Completely random question I know. I've just felt a lump under my chin, and now lying awake worried I have a tumour or something. I don't usually worry about my health, but somehow at half one in the morning it feels worse. I think it's probably a lymph node, but I don't remember ever feeling it before, but then I don't regularly feel under my chin!
If other people can feel something there than I'll much happier! I've been to the dentist recently, so I'd hope that if there was anything obviously weird he might have noticed. If you imagine the arch of your lower jaw it's pretty much in the middle, maybe slightly closer to the back than the front.
