The theory proposes therefore that physical pain and social pain (i.e. two radically differing kinds of suffering) share a common phenomenological and neurological basis. According to David Pearce's online manifesto "The Hedonistic Imperative", [30] suffering is the avoidable result of Darwinian evolution.

South African neuroscientists presented evidence that there was a physiological link on a continuum between pain and pleasure in 1980. First, the neuroscientists, Mark Gillman and Fred Lichtigfeld demonstrated that there were two endogenous endorphin systems, one pain producing and the other pain relieving.
There are three different types of pain based on the duration of the sensations: acute, episodic, and chronic. The most common are acute and chronic. Acute pain occurs suddenly, is sharp, and goes away once the issue is treated. Acute pain is caused by things like broken bones, childbirth, strained muscles, or burns. [5]
The authors proposed that both thin (pain) and large diameter (touch, pressure, vibration) nerve fibers carry information from the site of injury to two destinations in the dorsal horn of the spinal cord: transmission cells that carry the pain signal up to the brain, and inhibitory interneurons that impede transmission cell activity.
The International Association for the Study of Pain (IASP) defines chronic pain as a general pain without biological value that sometimes continues even after the healing of the affected area; [8] [9] a type of pain that cannot be classified as acute pain [b] and lasts longer than expected to heal, or typically, pain that has been experienced on most days or daily for the past six months, is ...
Martian pain is, to him, pain which occupies the same causal role as our pain, but has a very different physical realization (e.g. the Martian feels pain due to the activation of an elaborate internal hydraulic system rather than, for example, the firing of C-fibers). Both of these phenomena, Lewis claims, are pain, and must be accounted for in ...
Pain tolerance is the maximum level of pain that a person is able to tolerate. Pain tolerance is distinct from pain threshold (the point at which pain begins to be felt). [1] The perception of pain that goes in to pain tolerance has two major components. First is the biological component—the headache or skin prickling that activates pain ...
