Is it okay to schedule an important appointment the day after getting Ultherapy?

I want to try Ulthera.
Scheduling a procedure date is harder than I thought.

I have a schedule where I receive it on a weekday and have to meet someone the very next day.
I'm curious how long the swelling or facial discomfort will last.

If it is before an important appointment, please let me know how many days apart you received it.
