Here’s a compelling article from Rachel Zoffness. It’s called What Changes Pain?
It shares some perceptive insights. Here’s one that’s particularly thought-provoking:
Pain is not an accurate indicator of tissue damage. You can experience terrible pain in the complete absence of bodily harm (e.g., a nail in the shoe but not the foot), and little pain in the presence of significant damage (e.g. a nail to the face!). That is: just because something hurts does not necessarily mean your body is in danger of harm. “Hurt” and “harm” are not the same.
