This is in the middle of DH's back I thought it was a wart (DD has lots), but I'm not convinced it is.
DH has 100s of moles all over him, is fair with blonde hair and blue eyes, but his skin tans darker than mine and he used to sunbathe without suncream and has done so since a teen (now 51). I'd never have noticed, but he was itching there and asked if he something crawling, which is when I noticed it.
