Hi, my 9 year old daughter s upper lip has a blue tinge and it is slightly but noticeably blue between her lip and nose. Her bottom lip is fine. She is not having trouble breathing. Her fingernails, gums, and tongue look fine. Should I be concerned?
I suppose that if she is not having any other problems and that the blue tinge is not increasing than you should wait and observe. However, you may take serial photographs of the site to compare from previous.
