It's probably a mild infection. I've gotten than with some of my tattoos, and I usually lose some ink in those spots as it heals, so you my want to consult with the artist, since you may need a touch up down the line. A week isn't long - your tattoo is still actively healing. Wash it several times a day and use a&d ointment or an unscented lotion after each washing. Don't scratch or pick at it. Do your best to keep it clean. If the infection seems to be getting worse over the next few days, contact the artist and/or a doctor.
