The pain is usually constant, described as aching or burning, and often affects both sides of the face (this is almost never the case in patients with trigeminal neuralgia). The pain frequently involves areas of the head, face, and neck that are outside the sensory territories that are supplied by the trigeminal nerve.
In these instances there is also a more prolonged lower severity background pain that can be present for over 50% of the time and is described more as a burning or prickling, rather than a shock. Trigeminal pain can also occur after an attack of herpes zoster. Post-herpetic neuralgia has the same manifestations as in other parts of the body.
In the case of trigeminal neuralgia, the affected nerves are responsible for sensing touch, temperature sensation and pressure sensation in the facial area from the jaw to the forehead. The disorder generally causes short episodes of excruciating pain, usually for less than two minutes and usually only one side of the face. The pain can be ...
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).
A migraine attack can be a debilitating condition. But a headache is just one part. There are other subtle warning symptoms to watch out for, neurologists say.
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.
"Early delayed radiation-induced myelopathy" can manifest from six weeks to six months after treatment; the usual symptom is a Lhermitte sign ("a brief, unpleasant sensation of numbness, tingling and often electric-like discharge going from the neck to the spine and extremities, triggered by neck flexion"), usually followed by improvement two ...
