Is it normal to feel pain on the jawline & a small lump that is tender to touch after my 1st session of Exilis Elite? (photo)

I had my first session of Exilis Treatment for the face 2 days ago and I noticed a slight change already with the tightening and lifting aspect. Though on my left side of the cheek (lower part) / jaw area, I can feel pain especially when it is being touched. When I try to press and put in just a bit pressure, its like I can feel there's a lump or swollen part? Its slightly evident on the photo because it looks a bit darker too. Is this incident normal? And would it also subside in the next days?
