Can Ultherapy trigger cystic acne instead of curing it?

I had Ultherapy on my chin and neck area on Monday. When I got home last night and removed my makeup I felt horrible bumps much like cystic acne all over my cheeks and neckline. Is that what people are referring to as "welts"? My skin was better at 14 WHEN I HAD HORRIBLE ACNE than it is right now. I'm flipping out about this because I'm assuming that the ultherapy triggered a recurrence of my cystic acne and I'm 42.
