Foot tattoos on a scale of one to ten?

I would like a tattoo across the top of my foot, a tiger lily with leaves and vines in full color. Everyone tells me this will hurt like the devil. I have one tattoo already on my back, and it didn't hurt very much to get. On one hand, I know the foot is very bony and therefore will hurt more than my back. On the other hand, no one who's told me that foot tattoos hurt actually has a tat on their foot. Sooo.... for people who DO have tats on their feet: On a scale on 1-10, how bad did it hurt?
