Hyperalgesia (/ ˌ h aɪ p ər æ l ˈ dʒ iː z i ə / or /-s i ə /; hyper from Greek ὑπέρ (huper) 'over' + -algesia from Greek ἄλγος (algos) 'pain') is an abnormally increased sensitivity to pain, which may be caused by damage to nociceptors or peripheral nerves and can cause hypersensitivity to stimulus.
This can cause sensitivity to hot, cold, or sweet foods and beverages. Gum disease: Gum disease can cause sensitive teeth by exposing the roots of the teeth. As gum disease progresses, the gums may begin to recede, exposing the sensitive roots of the teeth. This can cause pain and discomfort when eating or drinking.
This causes shifts in pressure within the dentine, which stimulate the myelinated nerves located in the pulp, causing the sensation of pain. [9] The main nerve fibres responsible for responding to the stimuli are mostly type A-beta (Aβ) , [ 10 ] which carry tactile information, [ 11 ] and some A-delta (Aδ) nerves, [ 12 ] which relay pain and ...
Migraine causes a "severe throbbing or pounding headache with light or sound sensitivity and sometimes nausea," noted Dr. Timothy A. Collins, chief of the Division of Headache and Pain at Duke ...
Opioid-induced hyperalgesia (OIH) or opioid-induced abnormal pain sensitivity, also called paradoxical hyperalgesia, is an uncommon condition of generalized pain caused by the long-term use of high dosages of opioids [1] such as morphine, [2] oxycodone, [3] and methadone. [4] [5] OIH is not necessarily confined to the original affected site. [6]
Complex regional pain syndrome is a multifactorial disorder with clinical features of neurogenic inflammation (inflammation mediated by nerve cells), nociceptive sensitisation (which causes extreme sensitivity or allodynia), vasomotor dysfunction (blood flow problems which cause swelling and discolouration) and maladaptive neuroplasticity ...
The most common causes of pain are tension, stress, overuse, and minor injuries. Pain that racks your whole body—systemic pain—is more likely caused by an illness or condition, like ...
Based on the most common causes of toothache (dentin hypersensitivity, periodontitis, and pulpitis), the key indicators become localization of the pain (whether the pain is perceived as originating in a specific tooth), thermal sensitivity, pain on biting, spontaneity of the pain, and factors that make the pain worse.
