Hyperalgesia. Hyperalgesia (/ ˌhaɪpərælˈdʒiːziə / or /- siə /; 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.
Hyperesthesia is a condition that involves an abnormal increase in sensitivity to stimuli of the senses. Stimuli of the senses can include sound that one hears, foods that one tastes, textures that one feels, and so forth. Increased touch sensitivity is referred to as "tactile hyperesthesia", and increased sound sensitivity is called "auditory ...
Burning pain is the most common sensation, but patients also report pins and needles, pressing, lacerating, aching, and extreme bursts or constant sharp or unremitting excruciating pain. Individuals may have reduced sensitivity to touch in the areas affected by the pain, as if the part is 'falling asleep'.
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 ...
A family history of early chronic pain, a childhood history of pain, an emergence of broad pain following physical and/or psychosocial stress, a general hypersensitivity to touch, smell, noise, taste, hypervigilance, and various somatic symptoms (gastrointestinal, urology, gynecology, neurology), are all examples of these signals.

Dysesthesia is an unpleasant, abnormal sense of touch. Its etymology comes from the Greek word "dys," meaning "bad," and "aesthesis," which means "sensation" (abnormal sensation). It often presents as pain [1] but may also present as an inappropriate, but not discomforting, sensation. It is caused by lesions of the nervous system, peripheral or ...
Hypersensitivity (also called hypersensitivity reaction or intolerance) is an abnormal physiological condition in which there is an undesirable and adverse immune response to an antigen. [ 1 ][ 2 ] It is an abnormality in the immune system that causes immune diseases including allergies and autoimmunity. It is caused by many types of particles ...
The somatosensory system, or somatic sensory system is a subset of the sensory nervous system. It has two subdivisions, one for the detection of mechanosensory information related to touch, and the other for the nociception detection of pain and temperature. [1] The main functions of the somatosensory system are the perception of external ...
