Pain is a particularly elusive concept to articulate in words. We all understand the premise of pain, but such a subjective experience cannot be quantified with any measurable specificity.
Using scales and ratings we can attempt to convey our suffering in a meaningful way with some familiar context, yet in reality, such attempts are futile. Describing pain is akin to explaining anger, grief, or joy. Therein are stages, broad strokes of categorisation from a little to a lot, but nothing tangible insofar as is appreciable.
