What disease is numbness of hands and feet? Numbness is a symptom of the pathology of Qi and blood. Clinically, complex changes such as deficiency of the body's qi and excess of pathogenic factors, and a mixture of deficiency and excess are common. It is mostly caused by qi deficiency and poor circulation, blood deficiency, rheumatism, and phlegm and blood stasis. The symptom of numbness is based on deficiency of Qi and blood, with wind, cold, dampness, phlegm and blood stasis as symptoms. Although there are many causes of numbness, the pathogenesis is that qi and blood cannot flow normally, resulting in malnutrition of the skin, flesh and meridians. Insufficient Qi and blood, blockage of cold air, poor blood circulation, and inability of Qi and blood to nourish the meridians are the basic causes of numbness. Numbness of hands and feet is an independent disease caused by damage to the motor nerves of the limbs, mostly caused by hemiplegia due to stroke, diabetes, neuritis, cervical spondylosis, lumbar spondylosis, etc. The tiny blood vessels around the motor nerve fibers are blocked, compressing the motor nerve fibers, causing serious damage to the motor nerve fibers, reducing the nerve conduction ability and conduction speed, and causing numbness of the hands and feet. In severe cases, it may develop into painful symptoms such as limb paralysis and muscle atrophy.

People with diabetes may experience numbness in their hands and feet. If numbness, soreness, or swelling often occurs in any part of the body, blood sugar should be checked promptly, especially for the elderly. For example, if you have a cold or diarrhea, it will cause numbness in your hands and feet; if you stay in an environment containing hydrogen, arsenic, carbon disulfide, etc. for a long time, numbness in your hands and feet will also occur. The most common symptoms of neuritis are numbness of hands and feet, muscle atrophy, and weakness in the limbs. If you have diarrhea or a cold for half a month, it will cause neuritis. Numbness does not occur in the limbs at the same time, but occurs in a scattered manner. This means that local nerves are stimulated, such as a stroke after being drunk, coma causing stimulation of the head nerves, stimulation of the hand nerves by the elderly using crutches, upper limb numbness caused by cervical spondylosis, and leg numbness caused by stimulation of the lumbar shoulder nerves.

The above content is an introduction to what disease numbness of hands and feet is. I hope it can be of some help to you. We need targeted treatment for numbness in hands and feet.
