Pain and extreme tenderness after first Vanquish treatment on thighs. Is this normal?

I recently had my first Vanquish treatment on my thighs. A day later I started feeling extremely tender in the areas. It feels like extreme bruising but without the discoloration. I don't have any lumps or nodules, just the tenderness and pain. I can't lie on my side or sit a certain way without it being very painful. During treatment it got pretty uncomfortable for a short while, hot spots etc, but the discomfort eventually eased. It is much worse on my right leg than my left.
