What's wrong with my tattoo?

I got this done 10 days ago. Pretty much right after taking the second skin off I noticed a ring around the flower's center. The skin is bubbly and wrinkly. Why? I have 10+ other tattoos, and this has never happened before, although this is only my second colored piece. Help??
