Numbness turns to be a tingling sensation when we push the affected area. Usually, the sense of numbness in the affected limb, accompanied by a feeling of tingling in the skin looks like a needle prick. Numbness disappears quickly when the pressure is relieved for instance, when changing the sitting position. Usually, that feeling appears without warning until we change the position of the affected area. In most cases it is painless, and we usually feel it in the hands, arms, legs, or feet, although it can also appear in other parts of the body.
Why I Have Numbness
Numbness sensation is a result of the difficulty in passing blood into the nervous system. This is a sign that the nerve is “jerky”. That happens due to pressure on a part of the body. which will temporarily interfere with the nerve’s ability to communicate with the brain. In this case, this is not so dangerous. because this will disappear as soon as you change the position of the limb. But sometimes genetically the pressure happens in the disks that are located in the spine and neck. Compression on the neck’s disks will lead to numbness in the arms while compression on the back’ disks will lead to numbness in the legs. In the case of long time compression, you should search for help, by visiting the health center. That is because the pressure will be placed on the nerve for a long time even without you feel it so much. In some cases, you will feel it only when you sit in the wrong position. The distribution of the numbness depending on the affected disk. For example pressure on L4-L5- disk in the spine cause numbness in the foot.
What are The Differences Between Chronic Numbness and Temporary Numbness?
By changing the sitting position and moving or shaking the limbs may decreases the pressure and restore blood flow to the area and stop the tingling. When the tingling happens once, it called temporary numbness, for example, when you sit crossing legs on each other or sleeping in the wrong position. But when it returns, for more than one month, then this is called chronic numbness. Chronic numbness can be a sign of nervous disease or nerve damage. In this case, numbness can be signs of various disorders that are affecting the central nervous system, such as:
Video describe disc herniation and dehydration.
What Cause Numbness
Stroke or small stroke, when blood flow to the brain stops.
Multiple sclerosis, a disease that affects the central nervous system and affects the feeling of the body, where numbness in the face, arms, and legs is one of the most common early symptoms of the disease.
The height of the disks especially when it is congenitally relatively low.
Nerve injury or accident.
Squeeze the sciatic nerve, which travels from the lower pelvis to the buttocks and legs.
Dehydrogenation of the disks.
The existence of disk protrusion or extrusion.
Diabetes, as a blood sugar disorder, can damage nerves over time.
Lack of some vitamins, especially low levels of vitamin B1, B6, B12, which plays an essential role in nerve health.
Carpal tunnel syndrome, when the small tunnel that extends from the wrist to the palm narrows, causing pain and numbness in the forearm, hands, and fingers.
Dura sack dislocation and compression.
