Heres my toe i had tattooed 5 years ago.
Tatto artist said its the most painful place as the skin is so thick to break thru. He also said it would start to gradually rub away abit because of wear and tear of shoes rubbing against it.
It has started to rub off at the side.
As for the pain all i can say is i have 4 tattoos and the toe was painful but the others 2 on shoulders and 1 on thigh was just an annoying scratch.
