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.
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).
Cephalic aura, a perception of movement of the head or inside the head [24] Abdominal aura, such as an epigastric rising sensation [25] Nausea [26] Numbness or tingling (paresthesia) [27] Weakness on one side of the body (hemiparesis) [28] Feelings of being separated from or floating above one's body (dissociation) [29]
Lesions which destroy lower areas of the spinal trigeminal nucleus (but spare higher areas) preserve pain-temperature sensation in the nose (V 1), upper lip (V 2) and mouth (V 3) and remove pain-temperature sensation from the forehead (V 1), cheeks (V 2) and chin (V 3). Although analgesia in this distribution is "nonphysiologic" in the ...
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.
Modern trauma care includes a step called clearing the cervical spine, ruling out spinal cord injury if the patient is fully conscious and not under the influence of drugs or alcohol, displays no neurological deficits, has no pain in the middle of the neck and no other painful injuries that could distract from neck pain.

In children, the most common cause is a stroke of the ventral pons. [9]Unlike persistent vegetative state, in which the upper portions of the brain are damaged and the lower portions are spared, locked-in syndrome is essentially the opposite, caused by damage to specific portions of the lower brain and brainstem, with no damage to the upper brain.
A patient experiencing symptoms of hypoesthesia is often asked a series of questions to pinpoint the location and severity of the sensory disruption. A physical examination may follow where a doctor may tap lightly on the skin to determine how much feeling is present. Depending upon the location of the symptoms occurring, a doctor may recommend ...
