You should now understand that pain serves a purpose in your body, but that sometimes the pain system becomes oversensitive and inaccurate.
For example, something that should not be painful at all, such as a light touch or a breeze on your skin, can become highly painful. We have an internal bias towards recalling in detail anything dangerous or negative over more positive experiences. Your memory of someone insulted you will be recalled in great detail years later, but you will likely forget receiving warm compliments from the same person.
Recalling the negative experience is more helpful for our survival as it helps us to quickly learn to avoid threats.
