1. Concept of paresthesia in the Wikipedia Encyclopedia

Paraesthesia is defined as the abnormal sensation of the senses or the general sensibility that translates into a sense of numbness, tingling, numbness, etc., produced by a pathology in any sector of the central or peripheral nervous system structures.
Numbness and tingling are abnormal sensations that can occur in any part of the body, but are most common on the hands, feet, arms and legs.
This phenomenon can receive other names, such as: loss of sensation, loss of sensation, sensation of tingling and numbness, numbness or burning, or loss of sensation, superficial and deep.
Paraesthesia also usually appears when this damaged myelin (cells of glia form sheaths around neuronal axons and allow the isolation and the passage of nerve impulse)
Usually, the person does not notice easily when it happens. The affected area is numbed and stays rigid but flexible, being very difficult to place parts that move thanks to joint in normal operation. Presents a feeling of increased muscle density, followed by a continuous, sharp tingling and which again scathing support area on a hard or soft surface and extending to around a foot, hand, arm or leg of the body. When it starts to disappear, which does striving to operate the tip, clear and tingling sensations are reduced until it disappears, followed by a cool sensation of stretching by nerve terminals and that gradually resets to the rest of the body temperature.


2. Definition of paresthesia

Parestesia
It is known as paraesthesia to the feelings out of the ordinary to feel on your skin people suffering certain circulatory disorders or nervous system. These sensations can range from numbness to a tingling or itching.
Typically, that paraesthesia experience in the extremities, whether higher or lower, although the sensation can be extended to all parts of the body. There are different types of paresthesia according to how it is presented.
Occasionally, the subject not warns easily happens, although he acknowledges that you can not use your hands or legs normally. The feeling of paraesthesia increases when tip rests on any body. To eliminate these abnormal sensations, the person can move the limb in question to try to regain its usual operation.
The possible reasons of paraesthesia, include a nerve injuries, blood supply problems, hernias, strokes and various diseases (multiple sclerosis, hypothyroidism, and others).
Paraesthesia can also appear for an intoxication, lack of certain vitamins, a panic attack or even the simple in fact keep a same position for a long time.
It is possible, therefore, to experience paraesthesia if we remain seated quietly for several hours. When we try to incorporate ourselves, we probably feel that the legs are "asleep" and that, if we try to move them normally, appears a tingling. This feeling will disappear little by little, to move the legs and we try to walk normally again.


3. Definition of paresthesia


Paresthesia. Abnormal sensation of the senses or the general sensibility that translates into a feeling of tingling, numbness, numbness, etc., which is produced by a condition that can manifest itself in any sector of the structures of the nervous system, both central and peripheral.
Paraesthesia is characterized by numbness and tingling are abnormal sensations that can occur in any part of the body, but are most common on the hands, feet, arms and legs.
Paraesthesia is numbness that entails the loss of sensitivity or abnormal in any part of the body feeling. Feeling that a limb falls asleep, may be due to blood supply is not performed effectively. This can occur when we maintain the same position for a long time.
Recurrent episodes of partial or total loss of feeling in a zone, however, tend to be accompanied by an underlying neurological disorder. While any part of the body can be affected by this condition, people usually experience more numbness and tingling in the hands or legs. The facial numbness and tingling, or paresthesia facial, as it is also known, is not as common as the loss of sensation in hands or feet.
Usually, the person who suffers from paresthesia not realize easily when it happens. The affected part is numbed and stays stiff but flexible, making it very difficult to put in normal operation certain parts of the body that move thanks to the joints.
Presents a feeling of increased muscle density, followed by a characteristic tingling continuous, sharp and becomes scathing by supporting the affected area on any surface that extends a walk], hand, arm, or leg of the body. When this sense of discomfort starts to disappear, which is achieved striving to operate the tip, they are reduced to nothing, followed by a cool sensation of stretching by nerve terminals and that gradually resets the body temperature of the individual.
When they occur in the region of the face, these feelings are attributed to irritation of the nerves in the region. If the facial nerve that controls the muscles on both sides of the face is affected because of a medical condition, it can also suffer this problem. A neurological condition most common is neuralgia of the trigeminal nerve, this nerve is the main sensory of the face that send impulses from the brain to the skin; It also sends impulses to the muscles during Mastication. If it is pinched or compressed, can result in a partial or complete loss of sensation in the face.
Trigeminal neuralgia is a condition associated with severe facial pain; It's a disorder neuropathic can be caused by multiple sclerosis.
