Well my daughter who is now 2 gets the biggest cold sore on her face (yes face not lips). She has gotten them since the first time she got the flu. From what I know about herpes, if her immune system is down then she gets one. It's in the same place everytime and of course I am very worried that it is going to eventually leave a scar. Tiss the season for the flu and she's on her 2nd one in 4 weeks. Needless to say, she wasn't totally healed from the first one. The cold sore gets to be the size of a quarter and is very very thick. I have finally have a perscription that I'm suppose to give her 4 times a day, as soon as you see the first signs of it. Does anyone else out there have the same situation with a toddler? What specialists are out there?
