Allodynia is a condition in which pain is caused by a stimulus that does not normally elicit pain. [1] For example, sunburn can cause temporary allodynia, so that usually painless stimuli, such as wearing clothing or running cold or warm water over it, can be very painful. It is different from hyperalgesia, an exaggerated response from a ...
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.
Amplified musculoskeletal pain is a syndrome which is a set of characteristic symptoms and signs. Essentially, the syndrome is characterized by diffuse, ongoing, daily pain associated with relatively high levels of incapability and greater care-seeking behavior. The discomfort can be in the skin (allodynia), abdomen, throat (dysphagia ...
Neuropathic pain is pain caused by a lesion or disease of the somatosensory nervous system. [ 2 ][ 3 ] Neuropathic pain may be associated with abnormal sensations called dysesthesia or pain from normally non-painful stimuli (allodynia). It may have continuous and/or episodic (paroxysmal) components. The latter resemble stabbings or electric shocks.
Signs and symptoms of neuropathic pain include allodynia (pain caused by non-painful stimuli), hyperalgesia (an increase in pain perception due to painful stimuli), and paresthesia (abnormal sensations such as needle bites, tingling, itching, decreased or loss of sensitivity).

Studies suggest that hyperalgesia and allodynia are set off and sustained by certain groups of mechanosensitive sensory neurons. There is a general consensus among the scientific community that neuropeptides and NMDA receptors are crucial to the initiation of sensitization states such as hyperalgesia and allodynia.
This is commonly known as hyperalgesia. Inflammation is one common cause that results in the sensitization of nociceptors. Normally hyperalgesia ceases when inflammation goes down, however, sometimes genetic defects and/or repeated injury can result in allodynia: a completely non-noxious stimulus like light touch causes extreme pain. Allodynia ...
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 ...
