The tingling sensation in the body usually occurs due to compression of the nerve in that region, which is normally due to the lack of oxygen or problems in the nerve or central nervous system.
Usually this symptom is transient and improves with limb movement or local massages, which improve circulation. However, it can also indicate the presence of problems such as poor circulation, stroke, herniated disc and diabetes and so if it does not disappear within minutes, you should see a general practitioner or go to the hospital to identify the correct cause and start the most appropriate treatment.
1. Bad body positioning
Sitting, lying or standing in the same position for a long time, especially with crossed legs or with a weight on the limb causes poor circulation and compression in the local nerve, leading to the onset of tingling.
What to do: You should always try to move the body and stretch at least once every hour to stimulate blood circulation. During work or long plane trips, it is important to take small walks at least every 2 hours, getting up to go to the bathroom, drinking water or having a cup of coffee, for example
2. Herniated disk
Due to the wear and tear of the spine joint, compression occurs in the nerve that runs from the spine to the buttocks and legs, causing pain and numbness in the spine, which can radiate to the legs and toes.
What to do: A herniated disk should be treated to prevent the onset of the symptoms of this disease, and it is possible to use medications such as anti-inflammatory drugs, muscle relaxants and painkillers.
Diabetes causes poor blood circulation, especially in the extremities of the body such as the hands and feet, and numbness in this case may also signal the onset of developing wounds or ulcers in the affected region. See how to identify the first symptoms of diabetes.
