1) Pain is not simply caused by the stimulation of receptors in a linear sensory system.
2) The document discusses various paradoxes and dilemmas in understanding pain, such as the idea that specific causes lead to specific solutions.
3) It emphasizes that knowledge and understanding of pain is case specific and depends on certain premises, as different models and definitions of pain can be useful for different purposes.
Pain and Opioids: damage and danger, mechanism and meaningMark Sullivan
In this presentation, I argue that pain exists more to protect than to inform, so survival implications affect pain processing. The salience and valence of pain are continually adjusted to promote survival. For humans, physical survival depends on social survival, so our brains have evolved to make both physical and social injury painful, with our endogenous opioid system modulating both forms of pain to promote both forms of survival.

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

pain is whatever

Why does it matter?
If you really understand pain:
Then you’ll always believe people in pain
Then you’ll understand when pain becomes suffering
Then you’ll understand why communication matters
Then you’ll understand why so many treatments fail
Then your management will change

meaningless.
Educate your patient by all means,
but also let them educate you.
