Why numb limbs and what is paresthesia?
Source:
discuss in some cases, the numbness should not be ignored
When was the last time you had numb hands and feet? Perhaps you slept in an awkward position or sat not moving, but whatever it was, unpleasant feeling and a feeling of helplessness in these moments is quite annoying. Many believe that the cause of the temporary “loss” of one or the other is the obstruction of blood flow to the leg or arm, creating a tingling sensation and inability to control this part of the body within minutes. However, from the point of view of science limbs much more complex, and in some cases can indicate serious health problems.
Simple nuisance?
Numbness of the limbs is divided into “dangerous” and “safe”. Under the safe numbness neurologists mean numbness as a result of prolonged stay in one position or tighten clothing and accessories (such as strap shoes or a tight strap from a wrist watch). This type of numbness is not caused by internal diseases and is accompanied by an unpleasant tingling. But where do they come from?
As a result of prolonged compression — for example, if you were sleeping, tucked under his head , and when I woke up realized that she was numb — the body temporarily loses contact with the limb, as from the pressure of the nerve pathways are squeezed and can't transmit messages from the brain to certain parts of the body. Limb as if “asleep”, and when we change the position of the body and the pressure disappears, begins to Wake up. This process is accompanied by tingling as the nerves of the limbs resume communication with the brain. As soon as the normal link between this part of the body is adjusted, the tingling disappears. Such an unpleasant way the body alerts the brain that something is wrong. If the relationship is one of the limbs to the brain is interrupted for a long time, it can lead to nerve damage.
Limbs go numb for a variety of reasons, but the brain alerts us to possible danger.
But in the case of “dangerous” numbness it is in and of itself — that is, without squeezing it, and a long stay in one position. Moreover, if you feel numbness not only in the extremities but also in other parts of the body, this may indicate a variety . It should be noted that one form of limb numbness is called paresthesia. Paresthesia is accompanied by tingling, pins and needles. By the way, in some cases, the numbness is called paresthesia due to wisdom tooth (numbness of the tongue, cheeks or chin).
Other forms of paresthesia
You will be surprised, but paresthesia may be different.
While the most common way to check the paresthesia — to sit with folded hands or feet, there are other forms of paresthesia, which can have long-term effects or even take a few seconds. So, to suffer from carpal tunnel syndrome can be several years, but experience an uncomfortable tingling for a few seconds maybe even just hitting the elbow. Moreover, the paresthesia can bring love to a chili pepper, as it can cause a tingling sensation in the mouth. This is due to the pain receptor that responds to capsaicin — a chemical substance of chili.
Thus, an unpleasant tingling sensation are not only due to stay in an uncomfortable position, but could signal the beginning of the disease. Therefore, carefully follow all the signals their bodies and don't hesitate to visit a doctor.
