2nd BBL treatment gone wrong, any suggestions? (Photos)

I got my 2nd BBL treatment done today, and this is what happened on the 1st pass on the right side of my cheek. The red, raised, textured spots surfaced almost immediately. She stopped, and went to get an ice pack for them. I held the ice pack on the area while she did my forehead & nose. she then stopped and did not finish the treatment. She called in someone to look at the spots, they decided to take photos. They both said it could not be a burn because it was a BBL. What could have happened?
