Dark spots/sun spots look bigger and much worse after microdermabrasion! Help! (Photo)

I had a microdermabrasion treatment yesterday. The technician went lightly over my cheeks and forehead, but spent a lot of time on my dark spots. After the treatment and today, the dark spots look bigger! It looks similar to when the dermatologist froze one spot years ago...it almost looks like I have scabbing. Is this normal and will it heal? What do I do!
