I’m very concerned that this going to cause permanent scarring

I did plenty of research before I chose to move forward with Ultherapy and Ideal Image. At no point was it ever discussed with me that blistering, visible lines and deformities in the skin could or would be outcomes of the procedure. During the procedure on my chest it was extremely painful, and felt as if I was being burned. I contacted the office due to blistering and marks that started appearing later that same day and are are still present now 2 days later l. They informed me at first that those side effects were “completely normal” but then shortly later asked me to send pictures. They indicated that I “had an adverse reaction” to the treatment and that my skin must be really sensitive but assured me the blisters weren’t caused by burns nor are they permanent and will go away in 2 weeks and to follow up then. I’ve asked their medical director to contact me but have yet to hear from him, I even emailed him directly. I don’t understand why I would have blisters on my chest if it weren’t from being burned. They told me that they never change the heat from patient to patient or area to area, it’s all kept the same. But the skin on your chest is extremely thin and probably shouldn’t have the same level of heat as other areas on neck or face that have thicker skin. I’m very concerned that this going to cause permanent scarring and can’t stop crying and worrying that I’ve destroyed by skin by allowing them to perform this procedure on me. I’m so disappointed and will make an appt with my primary doctor within in the next couple of days for a second opinion.
