So Dd has white stuff/patches under her tongue and on the sides of her mouth. She says it feels like it’s growing up from under the skin. It’s hard and won’t scrape off. It’s slightly sore but not itching or burning. There is some red spots next to the white patch. She’s had it a week and is growing every day.
she does have autoimmune stuff going on so not sure if it’s related to that but she’s not had this before.
any ideas what else it might be apart from thrush?
