Strep throat can produce something called "strawberry tongue" where the tongue looks just like a strawberry. Perhaps she had strep throat?

Sometimes a viral infection like Coxsackie causes the full HFM (with sores in the mouth and on the fingers and/or toes) and sometimes it just causes the little blisters in the mouth (herpangina -- lovely name, eh?). Either way the main concern is dehydration when the pain is so bad that it keeps a kid from drinking, but it sounds like your daughter is eating and drinking okay. No specific treatment for it, so I agree with the PPs who said call if you want, but no need for a visit if she otherwise looks well and is acting herself.

Thanks. I'm pretty sure. She had hand, foot and mouth a couple of months ago and these don't look like the sores she had then (on the roof of her mouth). Plus there is no rash or any sores anywhere else on her body.

I'd do a call, not an appointment, but yes it sound like HFM. My son gave it to me. It sucks, but there isn't much you can do.

I agree on the possibility of hand/foot/mouth.

Are you sure they are canker sores and not hand, foot, and mouth (coxsackie)?

I'd call the doc to make sure. Any time there is an outbreak/rash of some sort, there is a risk of transmission to others.

My 3 year old had a low grade (101) fever for ~36 hours at the end of last week and complained of a sore throat and tongue. Fever was completely gone yesterday and she has been acting normally since. However, I noticed a couple of canker sores under her tongue yesterday, which I didn't notice before and assume they are related to the fever given the timing. These have made it painful for her to eat certain foods and today I've been applying orajel. Otherwise, she is perfectly happy and acting normally. I'm debating whether or not to call the ped tomorrow, although I'm not sure what they would do now that she seems to have gotten over whatever she had..... Would you?
