what is this on DDs lip/tongue???

[curlyLJ]

DD has what initially looked like a cold sore on her bottom lip, but after a few days it looked like it was on her tongue too - all over the tip.

I visited the GP who disagreed that it was a cold sore and said it looked like she had either banged her lip or eaten something too hot or that she was rubbing her tongue on her new top teeth. I disagreed with this diagnosis as she has defintely not eaten anything too hot and to be honest it doesn't explain why it is in 2 places and appeared at different times (2 days apart) but looks the same, like blisters.

He gave me some Aciclovir cream in case it was a cold sore (and because I insisted his opinion was wrong) but the blister on her lip looks even bigger now and is not improving.

SHe is teething a lot and so all the drool on her lips/chin isn't helping. She is also very irritable and isnt eating or sleeping well... (more so than previously when teething)

Any idea what this might be and if it is a cold sore, is that likely to make her so tetchy?

could be viral. a few things can cause mouth sores, hand foot & mouth etc.

Hmm, she's got no other real symptoms eg rash, cough etc. That's why I thought it was a cold sore.

Think I might need to go back to the GP (but see a different one) if it gets worse.

Has anyone come accross a cold sore actually in the mouth/on the tongue before??

My GP told me that my Dd's ulcers that were in her mouth, on her lips etc were coldsores, but as she had a few little red blisters on fingers and a couple of other places, plus she'd had a raging temp a few days before they came out, MN put me straight and I think it was HF&M.
Ask for another opinion.

any pictures of her tongue and mouth
