hi everyone i'm posting this on behalf of my sister
i will attach a photo but this appeared at the top of her neck/ under her chin probably about 2-3 weeks ago now at first we thought it was a bite so didn't question it but around a week ago it came up as it looks now but very faint and has progressively become more visible i think it is ringworm but wanted some other peoples opinions as ringworm can be easily mistaken with many other things
thank you in advance !
