Oh, that is GORGEOUS.

I'm a sucker for all black work, I must admit. For some reason black always itches the most for me, but it's part of the healing process. Try
really hard not to itch! It can pull of scabs and some ink may come with it. You can always get touch-ups, but avoiding those is a plus. I've found the back area can be more itchy than others too. Possibly psychological, since itching your own back is difficult anyway.
I use A&D ointment too, since that's what my artist recommends. Just don't overdo it or let it get too wet, since that can turn the scabs to mush...and again, they might come off prematurely.
Mind over matter is my tried and true anti-itch method.

Just keep reminding yourself that it's permanent, and it's beautiful, and the itching will be gone in a week or so.
