blisters on tongue

[kidsx4]

My 1 yr old ds has had a very high temp and has been of his food he normally has a dummy to sleep with but refused it all night, i have had a look in his mouth and he has blisters on his tongue, does anyone know what it is? TIA

does he have any on his hands or feet, could be hand foot and mouth virus

No that's what i thought.

Could be a first herpetic infection - ie coldsore
Apparently the first time you get blisters on the tongue, a burnt feeling in the mouth and you go off your food.
This si what my dentist said when we all got this - I am dubious though as dh and I have had coldsores before.

i'd take him to the dr to get him checked out

You don't always get blisters with the first cold sore infection, although it is a possibility.
Combined with his temperature, I would say hand foot and mouth. Sometimes the spots/blisters can just appear in the mouth; sometimes just on the hands or feet.

yes, hand foot and mouth.
the blisters come first iirc
