Hi i notice for the very first time ever in my life that i had 2 white dots in the inside of my lips both on my gum, but it disappeared 2 days later, one of them i still can feel but cant really see it and the other one just vanished. now this is my concern, my 4 year old son who loves to kiss me said that the inside of his lower lip is hurting as well, when i took a look it was little tiny bumps rarely visisble, no color change. Is he going to have canker sore or herpes?
