Knowra Pain Pain Pain is an unpleasant sensory and emotional experience associated with, or resembling that associated with, actual or potential tissue damage. It can occur with or without detectable tissue injury.
Nociception : The neural process of detecting and encoding potentially tissue-damaging stimuli. It supplies many pain signals, though nociception and pain are not the same experience.
Acute pain : Pain that begins with injury or illness and generally resolves as the underlying cause heals. It illustrates pain's protective role during a time-limited threat.
Pain assessment : The evaluation of pain's intensity, quality, timing, impact, and possible causes. Pain is subjective, so assessment combines self-report with clinical context.
Tissue damage : Structural injury or dysfunction in body tissues caused by disease, trauma, or other processes. Pain may accompany tissue damage, but the amount of damage does not reliably predict pain.
Fear-avoidance model : A model in which pain-related fear promotes avoidance, deconditioning, and disability, which can sustain distress. It explains one pathway by which persistent pain can restrict activity and reinforce itself.
Nociceptor : A sensory neuron or nerve ending that responds to potentially damaging mechanical, thermal, or chemical stimuli. These peripheral sensors can initiate signals that contribute to pain.
Chronic pain : Pain that persists or recurs beyond the usual course of healing, often lasting longer than three months. It shows how pain can become a condition rather than a short-lived warning.
Analgesic : A medicine or intervention that reduces pain without necessarily causing loss of consciousness. Analgesia is a central goal of pain treatment, though relief may be partial.
Neuropathic pain : Pain caused by a lesion or disease of the somatosensory nervous system. This pain category arises from nervous-system dysfunction rather than ordinary tissue injury alone.
Pain catastrophizing : A pattern of magnifying pain threat, dwelling on pain, and feeling unable to cope with it. It is associated with greater distress and can shape the experience and management of pain.
