In medical language, pins and needles often referred to as paresthesias. A sensation that is felt without any stimulus from outside. Paresthesias sensation is not only a sense of tingling, but can also sense the heat, taste like a punctured-puncture. pins and needles Pain can be felt in the hands, feet in advance, and in all parts of our body.
Basically tingling is a symptom manifestation of the sensory nervous system disorders due to electrical stimulation in the system was not fully channeled to cause all kinds. The simplest, for example, blood road closed due to a specific body part bent for too long.
Tingling that is not accompanied by other symptoms usually indicate a disturbance in the receptors in the skin or in the branches of peripheral nerves. But we must be more vigilant if there are symptoms other than tingling. Not only paralysis, tingling can also be accompanied by visual impairment, hearing loss, a combination of both, or other.
Disturbance
Nerves are the fibers that connect the organ with the central nervous system of the brain and spinal cord and nervous system with another. To set the sense and motion, the body is controlled by motor nerves.
Sensory nerves to regulate taste, while the autonomic nervous is that having the right to autonomy to regulate the movement and feeling, which is not influenced by sensory or motor. Examples of organs are regulated cardiac autonomic nervous is still beating, though not ruled motor and sensory nerves.
Motor and sensory nerves are working closely with central nervous system and peripheral nerves. Edge or peripheral nervous system consists of the radial nerve, ulnar, median and peroneus profundus. The three nerves in the hands first and the fourth is located in the foot.
The radial nerve is above, from above the thumb up to the armpit. Ulnar nerve is located at the bottom, from little finger to the armpits down. While somewhat specific because the median nerve in the middle, leading to carpal tunnel in the palm of the hand. Or rather on the inner wrist and into your fingers.
Shock or tingling is due to the existence of an impaired nervous system. A disorder that usually arises is the following:
* The radial nerve
“When such shock, could be affected is the radial or ulnar nerve. That part is accidentally touched, and there arose a reaction. “Saiful said. Taste like the real shock is not dangerous. But if it continues, would be wary. It can cause paralysis or abnormal hand.
Usually this occurs because the radial nerve pinched, or pressed a hard object in the long term. How long? Um cannot be determined, but certainly more than an hour.
Examples of behaviors that can lead to drop the hand is put to bed with hands behind head. Or fall asleep while sitting, with the armpit on the back seat.
* Ulnar nerve
Meanwhile, if the ulnar nerve is disturbed, can cause the fingers to bend into the palm of the hand you know! Or any other name Claw hand. So, palms resemble bird talons that can not be recovered as usual.
This disorder usually occurs because for too long put your elbows on the table. Also sleep on his side and used his hand to the head. Driving habits of bus drivers or truck also trigger the disorder in the ulnar nerve.
“Because the steering wheel for large vehicles such as trucks or buses that once great khan. So that the hands are often the driver put his hand on the steering wheel in the long term. Well, if it continues, then the hand like shock or tingling. If that happens, well it could be a sign of paralysis of the hand, “says this bespectacled doctor.
* Median Nerve
For the median nerve disorder is slightly different than the other two, because the median nerve motor function and there is not only a sensory, so disturbed is the taste. Thus, the discomfort associated with the affected nerve is prolonged pain and not paralysis.
Disorders that commonly called the carpal canal syndrome is pain in the fingers and palms. Sometimes too hot and the smaller muscles around it.
Behavior that used to cause a nervous breakdown this is an activity that involves the palms, such as writing, typing, mengulek, rotate the screwdriver, washing, sweeping, knitting and so on.
* Nerve peroneus
The next disturbance is paralysis in the legs due to peroneus profundus nerve. Feet be like a chicken leg is a step, ie foot could not tread the ground with a flat or drop foot. The feet also do not have the strength to walk. Become, to step foot was dragged for so it is impossible to walk normally.
This disorder is due to someone used to sit with crossed legs or it could be due to frequent cross-legged for a long time.
