DD blister in mouth. Warning grim pic!

[FraterculaArctica]

DD9 suddenly started complaining of a sore mouth this evening. When we looked in she had this massive blister like thing, dark pink/red.

Anyone seen anything like this before? Guessing it's a blood blister but no idea why so enormous. Would you take her to the pharmacist/GP if it's not better in the morning?

My DD had this and it was Hand Foot and Mouth Discease

Seconding HFM. When we had it we got it in the mouth first. Check fingers and toes!

Thank you! I wouldn't have thought of that. Will look up the symptoms and see if they fit.
