It is in the nature of chronic diseases that symptoms manifest most when our survival instincts (fight, flight, freeze) take over our body's function. This is why the severity and range of symptoms can vary moment to moment, hour to hour, or day by day, according to how stressed or how relaxed we are in that moment, for most chronic diseases. Here, I use the word stress in its widest possible interpretation, to denote anything which may be troubling us in the present moment, e.g. feelings, accidents, trauma, troublesome relationships, financial problems, small unresolved situations from childhood, that may seem insignificant to an adult.
