First, people with diabetes will be numb in their hands and feet. As long as numbness, soreness and swelling often appear in any part of the body, it is necessary to check blood sugar in time, especially in the elderly.
The second is numbness caused by drugs or chemicals. For example, when you have a cold or diarrhea, taking berberine or furazolidone will cause numbness in your hands and feet; Stay in an environment containing hydrogen, arsenic, carbon disulfide, etc. After a long time, it will also cause numbness in hands and feet.
The third is numbness caused by neuritis. The most common symptoms of neuritis are numbness of hands and feet, muscular atrophy and weakness of limbs. If you have diarrhea or catch a cold for half a month, it will cause neuritis.
Fourth, the limbs are numb. The limbs are not numb at the same time, but scattered numbness. This situation is that local nerves are stimulated, such as stroke after drunkenness, nerve stimulation to the head in coma, nerve stimulation to the hands of the elderly with crutches, numbness of the upper limbs caused by cervical spondylosis, and numbness of the legs caused by waist and shoulder nerve stimulation.
Suggestion:
Numbness of hands and feet can also be caused by deficiency of qi and blood, both of which are blood deficiency. Because yang is weak, it leads to blood deficiency, yang can't circulate blood, and blood can't reach the end of blood vessels. Hands and feet are limbs of human body, so blood deficiency will make you feel numb.
Pay attention to maintenance at ordinary times, and eat less cold food for yang deficiency.
