I noticed this lump on my DD’s leg a week or so ago and brushed it off as a bite or something but it’s still there now. She hasn’t complained about it so I don’t think it hurts her or anything.
My initial thought was that maybe it’s a wart but my Google search didn’t bring up pictures that look quite like it.
It’s pink in colour, less than centimetre in diameter and on her knee if that makes a difference.
