Can You Say Cold Sore?

My poor little girl has got her 1st cold sore and boy is it a doozy!! She woke up on the 7th of May with these clusters of blisters on her lip. At first I tought it was impentigo but the school nurse assured me it was a cold sore. We tried to dry it up as soon as possible with some Camphophanique(sp?) and it did the trick. It is now healing nicely!
