title: [When pain cannot be expressed].
abstract: How pain is felt is a personal and private fact which is almost impossible to measure, which eludes any attempt to grasp and describe it and any desire to convey to another person its intensity and its nature. The challenge is to understand the pain, to assess it and manage it.
