Is physical pain only 'remembered' or 'anticipated' so actually there is no pain? If so, how to understand?

I don't know whether this is an Buddhist point of view, but it comes from Byron Katie. She says that there is no real pain because it is only remembered or anticipated. But I don't understand that. So is this also a Buddhist kind of mediation, if so can you explain how physical pain doesn't exists in the now? For example if I chew on my tongue it can hurt very much, but for me that pain does really exist at that moment and the time after. So how can she say it is only a remembering or anticipation of it? How does buddhism sees this? https://www.youtube.com/watch?v=9Ul5UI6KO50&t=1140 (scroll to time min 19:00 through 20:20)
