My 2 year old had trouble sleeping tonight. She has a stuffy most so I thought it was a cold. She woke up crying and I couldn't get her to sleep so I took her downstairs. I noticed her upper lip is fat and swollen. Not like a bump, the whole thing. She seems uncomfortable but not in pain. We were just at the dentist today because her tooth is broken but there was no infection and like I said, she isn't I'm pain. I'm waiting for dr to call me back. What do you think it is.
