Blister + tattoo removal. Should I be concerned? (photos)

I had my first laser tattoo removal session yesterday. The doctor only out antibiotic ointment on the top two butterflies and not on the bottom one. His rationale was that the top two were bleeding. Well, this morning I woke up and the bottom butterfly had significant blisters. Should I be concerned? The doctor used the Quanta Q, plus C laser. I cleaned the area with antiseptic and put on neosporin. Any advice that you could give me would be greatly appreciated.
