You can't really tell at this point what the
spotsBirthmarks - pigmented
Liver spots
Measles, koplik spots - close-up
Mongolian blue spots will look like when they heal--it takes a few weeks. I'm not surprised that they look scabbed and unpleasant a few days after the surgery, but that doesn't mean they won't heal just fine.
Of course, I don't know what technique your dermatologist used. You really should consider calling him or her up and asking. I understand your skepticism, but really, the best way to get a read on what's going on is to ask the doctor who performed the procedure what the likely healing course is supposed to be.
Best.
