All behaviors in Pain Phenomena
Acute Pain
A sharp, time-limited pain signal that arrives when tissue is threatened or damaged — the body's clearest invitation to stop, attend, and let the system update.
Allodynia
Pain produced by a stimulus that is not normally painful — a feather, a sheet, a breeze — because the nervous system's pain-mapping has been miscalibrated by injury, illness, or sustained sensitisation.
Central Sensitization
A well-documented neuroscience state in which the central nervous system becomes hyperresponsive to input — the volume of pain processing turns up, so ordinary signals start arriving as pain and existing pain feels louder.
Chronic Pain
Pain that has outlived its original tissue signal and is now produced by a sensitised, well-rehearsed alarm system — real in every felt sense, but no longer a one-to-one report of damage.
Fear of Pain
The direct aversive response to pain or to movements and situations expected to produce pain — a clean Threat System signal that, when it dominates behaviour, drives the fear-avoidance cycle of deconditioning and amplification.
Functional Pain
Real, persistent pain without a clearly identifiable structural cause — produced by an amplifying loop between threat-prediction and pain output that turns ordinary sensory input into a loud, sustained experience.
Gate Control of Pain
The mechanism, proposed by Melzack and Wall, by which non-painful sensory input and descending signals from the brain modulate — open or close — the transmission of pain signals at the spinal cord level.
Hyperalgesia
An amplified pain response to a stimulus that is already painful — the same pinprick, pressure, or heat that used to register as small pain now registers as large, because the nervous system's gain on pain processing has been turned up.
Hypoalgesia
A reduced sensitivity to pain — sometimes protective and adaptive (under acute stress, in an athlete mid-event), sometimes worrying (when a chronic loss of warning lets unseen damage progress).
Neuropathic Pain
Pain that originates from injury or dysfunction in the nerves themselves — burning, electric, shooting, or numb-tinged — produced not by tissue damage in the conventional sense but by a nervous system whose signalling has been altered.
Nocebo Pain
Real pain produced or amplified by negative expectation — a warned-about side effect, a feared diagnostic label, an anxious context — where the Threat System's prediction is realised in the body as a felt event.
Nociceptive Pain
Pain produced when specialised receptors signal actual or potential tissue damage — the textbook signal that the Threat System is built to translate, and the kind of pain most cleanly amenable to being met.
Pain Acceptance
The willingness to feel pain that cannot be eliminated while continuing to live by values — not resignation, not a cure, but the metabolic move that frees the energy otherwise spent fighting an unwinnable battle.
Pain Anticipation Spike
A sharp rise in felt-pain that arrives before the noxious stimulus does — the brain's prediction system generating, in real time, the pain it expects, sometimes more intensely than the actual stimulus eventually produces.
Pain Anxiety
Anticipatory tension about future pain — the Threat System over-issuing predictions of harm, so that the system spends its energy bracing for pain that has not yet arrived rather than relating to the pain that is.
Pain Avoidance
The behavioural pattern of restricting movement, activity, and engagement to escape current or anticipated pain — short-term relief that, sustained, produces deconditioning, central sensitisation, and a narrower life.
Pain Catastrophizing
A pain-meaning loop in which the worst predicted outcome — endlessness, devastation, ruin — becomes the dominant signal, amplifying perceived pain beyond what the original tissue event would generate alone.
Pain Flare Pattern
The recurring spike-then-recede pattern characteristic of chronic and recurrent pain — where the body returns to a higher baseline temporarily and the relationship to the spike (panic vs. observe-and-pace) decides whether the flare leaves residue or deposit.
Pain Grief
The mourning specific to chronic or altered-capacity pain — for the body one had, the life one had expected, the activities now narrowed — which leaves a deposit when contacted and accumulates as residue when routed into bitterness, denial, or numbed acceptance.
Pain Identity Reformation
The slow, hard, generative work of re-forming a self that includes pain without being defined by it — neither denial nor fusion, but a remade identity in honest contact with the actual body.
Pain Memory
The body's tendency to encode painful experiences into the nervous system in a way that lets the loop re-fire later — sometimes with fresh triggers, sometimes with no obvious trigger at all.
Pain Modulation
The brain's continuous capacity to amplify or dampen incoming pain signals via descending pathways and endogenous chemistry — the reason the same nociceptive input produces very different felt experiences across contexts.
Pain Threshold
The point at which a stimulus stops being mere sensation and starts being registered as pain — a moving line set by tissue, nervous system, attention, and meaning together.
Pain Tolerance
How much pain a person will endure before they change behaviour — a cultural, identity-laden, and heavily variable measure that is often confused with the more biological pain threshold.
Pain-Driven Limitation
The gradual organisation of choices, plans, and relationships around the avoidance of pain — until the life lived is decisively narrower than the life that was, and the unlived life becomes its own form of residue.
Pain-Free Window Optimization
The skilled practice of using lower-pain windows to do what matters most — paced, deliberate, and oriented toward valued action rather than maximal output — so that the better hours leave a deposit instead of fueling the next flare.
Pain-Identity Fusion
The slow merger of a diagnostic label, a symptom history, or a daily pain experience with the felt sense of who one is — until *I am a pain person* operates as the self rather than as a description of a body.
Phantom Limb Pain
Pain experienced in a limb that is no longer present, generated by the brain's persistent map of the body that has not yet updated to reflect the limb's absence.
Placebo Analgesia
The measurable reduction of pain produced by meaning itself — expectation, ritual, relationship, context — recruiting the body's own endogenous opioid and descending modulation systems to dampen a real nociceptive signal.
Psychogenic Pain
An older clinical term for pain whose primary generator is in the central nervous system and emotional regulation rather than in peripheral tissue damage — fully real in felt experience, and a category whose name modern pain science is increasingly careful with.
Referred Pain
Pain felt in one part of the body whose actual source is elsewhere — the nervous system points correctly to a signal it cannot resolve, and the conscious mind reads the wrong address.
Visceral Pain
Pain originating in the internal organs — gut, heart, lungs, pelvis — typically diffuse, hard to localise, and carrying strong emotional signal weight because the viscera and the emotional system share neural real estate.
