Fear of Pain
Algophobia
Waddell reported in 1987 that for at least ten per cent of adults, pain persists long after any identifiable organic pathology has healed. That figure is where this entry begins, because it defines the population in which fear of pain does real damage.
For most people, acute pain triggers short-term adaptive processes that assist recovery, and it fades as healing progresses. Where it does not, the fear takes over the job the pain was doing.
How the pain loop runs
Persistent pain leads to catastrophic thinking about what the pain means. Pain catastrophising leads to pain-related fears, and those fears amplify the pain experience itself.
The behaviours follow:
- hypervigilance, meaning excessive attention to pain
- guarding or safety behaviours, such as restricting the range of joint motion
- escape or avoidance, meaning withdrawal from physical, occupational and social activity
Every one of those is intended to reduce pain. In the long term they perpetuate and worsen it. That is the sentence this entry exists for, and it makes fear of pain the clearest example in the catalogue of a fear that manufactures its object rather than merely responding to one.
What exactly is feared is not established
The material is honest about a gap that most accounts skate over. It is not clear whether the primary object of pain-related fear is the painful sensations themselves, the activities associated with those sensations, or reinjury.
The second of those has its own term, kinesiophobia, fear of movement. The distinction matters practically, because a person avoiding sensations and a person avoiding movement need different things asked of them.
Which constructs the models separate
Fear-avoidance models of pain identify three anxiety-related constructs associated with pain-related disability: pain catastrophising, pain anxiety, and anxiety sensitivity, the last being fear of the arousal-related bodily sensations that accompany anxiety.
Pain-related fear and pain anxiety are separated by what they produce. Fear tends to motivate defensive behaviour, meaning escape. Anxiety tends to motivate preventative behaviour. One reacts and one anticipates, and a treatment aimed at the wrong one will miss.
The withdrawal these models describe reaches work, leisure, social life and sexual activity, and the reduced functioning that follows produces mood disturbance: irritability, frustration, anger and depression.
Why pain is a strange object to fear
The International Association for the Study of Pain defines pain as an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage.
It is universal and it is necessary. It motivates withdrawal from harmful situations, protection of an injured part while it heals, and avoidance of similar experiences afterwards. A fear of the signal that keeps a person out of danger is a fear of a functioning alarm.
What else the record holds
Sabino Metta, a behavioural psychologist, describes the phobic reaction as learned behaviour, and gives an example worth keeping: an elderly person who hears about the various ailments and pains of all their friends begins to anticipate the problems and to experience the results before anything has happened to them. People with this problem probably have hyperalgesia, an increased sensitivity to pain.
The Fear of Pain Questionnaire, currently in its third version, has been used to test for algophobia and was found to have good internal consistency and test-retest reliability.
The names are numerous and inconsistent. Algophobia, algiophobia and agliophobia all appear, from the Greek algos, which gives neuralgia, arthralgia and cephalgia. The 2008 printed encyclopedia files fear of pain under odynesphobia, odynephobia and odynophobia instead, built on a different Greek root for pain. Six spellings across two roots, for a fear with one of the better-validated instruments in this catalogue.
Told apart
Often confused with Fear of Pain
- Fear of NeedlesNeedle fear is frequently described as a fear of pain and behaves unlike one, producing the biphasic faint of the blood-injection-injury group rather than the guarding and avoidance of pain-related fear.
- Fear of SurgeryThe adult version of surgical fear is largely a fear of the pain that follows rather than of the operation, which makes algophobia the fear underneath most of it.
- Health AnxietyBoth interpret bodily sensations as evidence of something worse. One expects illness and the other expects damage, and both produce hypervigilance toward the body.
Common questions
Questions about Algophobia
- Can fearing pain make pain worse?
- Yes, and the mechanism is documented rather than metaphorical. Pain catastrophising produces pain-related fears which amplify the pain experience, and the behaviours that follow, hypervigilance, guarding and avoidance, are all intended to reduce pain and in the long term perpetuate and worsen it.
- What exactly is feared?
- Not established, and the literature says so. It is unclear whether the primary object is the painful sensations themselves, the activities associated with them, which has its own term, kinesiophobia, or reinjury. The distinction matters, because avoiding sensations and avoiding movement call for different treatment.
- How many people have pain that outlasts the injury?
- At least ten per cent of adults, on Waddell's 1987 figure. For most people acute pain triggers short-term adaptive processes that assist recovery and fades as healing progresses; in that minority it persists long after any identifiable organic pathology has healed.
- What is the difference between pain fear and pain anxiety?
- What they make a person do. Pain-related fear tends to motivate defensive behaviour, meaning escape, while pain anxiety tends to motivate preventative behaviour. One reacts and the other anticipates, and fear-avoidance models list both alongside anxiety sensitivity as the three constructs associated with pain-related disability.
- Why is pain a strange thing to fear?
- Because it works. The International Association for the Study of Pain defines it as an unpleasant sensory and emotional experience associated with actual or potential tissue damage, and it is necessary for survival: it drives withdrawal from harm, protection of an injured part while it heals, and avoidance afterwards. Fearing it is fearing a functioning alarm.
- Why are there six names?
- Two Greek roots and no agreement. Algophobia, algiophobia and agliophobia are built on algos, which gives neuralgia and arthralgia. The 2008 printed encyclopedia uses odynesphobia, odynephobia and odynophobia instead, built on odyne. No source prefers one over the others.
