My daughter had a pretty bad accident yesterday where she was walking along some wooden stepping stone things in a playground and she slipped off one and bashed her mouth off the next one pretty hard. She was bleeding and cried for a bit but she seemed okay overall. It looked very bad, the whole top of her mouth was swollen. The swelling has come down a good bit overnight but she has got yellow blisters where she cut it. Is there anything I should do with it?
