How painful is a lifting procedure?

I'm looking into lifting procedures, but I'm a little worried because I've heard a lot of people say it's painful.
I'm especially hesitant about Ulthera because I've seen a lot of posts saying it's painful.
I am curious if there is a significant difference in pain depending on the type of lifting procedure, and I would also like to know if the pain level is bearable.
I'm a bit of a scaredy-cat, so I'm worried I might end up canceling after making the reservation.
