After One Session New Denting

I did a session yesterday. The treatment felt good. No pain at all. At night when I undressed to admire the treatment results I was horrified that the sides and back of my legs that were previously smooth had rivets and dents. How could this have happened? I don’t known if the fat tissue moved during the treatment or the skin stretched as some reviewers pointed out. I will not be going back for anymore treatments! If somehow this issue resolves itself in a few days I will come back to update you all.
