The sensation can feel like it goes up or down the spine. It is painful for some, although others might simply feel strange sensations. [1] In many people, it is elicited by bending the head forward. [2] It can also be evoked when a practitioner pounds on the cervical spine while the neck is flexed; this is caused by involvement of the ...
Similar brief shocks can be experienced when any other nerve is tweaked (e.g. a pinched neck nerve may cause a brief shock-like paresthesia toward the scalp). In the older age group, spinal column irregularities may tweak the spinal cord briefly when the head or back is turned, flexed, or extended into brief uncommon positions (Lhermitte's sign).
[citation needed] Electric shock which does not lead to death has been shown to cause neuropathy in some cases at the site where the current entered the body. [10] The neurologic symptoms of electrical injury may occur immediately, which traditionally have a higher likelihood for healing, though they may also be delayed by days to years. [10]
Lhermitte's sign is an electrical sensation that runs down the back and into the limbs and is produced by bending the neck forward. The sign suggests a lesion of the dorsal columns of the cervical cord or of the caudal medulla , correlating significantly with cervical MRI abnormalities. [ 111 ]
Dysesthesia is distinct in that it can, but not necessarily, refer to spontaneous sensations in the absence of stimuli. In the case of an evoked dysesthetic sensation, such as by the touch of clothing, the sensation is characterized not simply by an exaggeration of the feeling, but rather by a completely inappropriate sensation such as burning.
Neuropathic pain has profound physiological effects on the brain which can manifest as psychological disorders. Rodent models where the social effects of chronic pain can be isolated from other factors suggest that induction of chronic pain can cause anxio-depressive symptoms and that particular circuits in the brain have a direct connection.
This includes aching teeth, ear aches, feeling of fullness in sinuses, cheek pain, pain in forehead and temples, jaw pain, pain around eyes, and occasional electric shock-like stabs. Unlike typical neuralgia, this form can also cause pain in the back of the scalp and neck.
Neurogenic shock is diagnosed based on a person's symptoms and blood pressure levels. Neurogenic shock's presentation includes: [7] [8] - warm and pink skin - labored breathing - low blood pressure - dizziness - anxiety - history of trauma to head or upper spine. - if the injury is to the head or neck, hoarseness or difficulty swallowing may occur.
