The presence of numbness in the hands and feet is not necessarily peripheral neuropathy. Numbness of the hands and feet may be affected by physiological factors in the living environment, or it may be caused by primary diseases, medication, nutritional deficiencies and metabolic disorders.
1. Physiological factors: if you live in a damp, cold environment for a long time, it is easy to make wind and cold invade the body, which can cause numbness of hands and feet.
2. Pathologic factors:
(1) primary diseases: polyneuritis, carpal tunnel syndrome, tennis elbow, cervical and lumbar spine disease and other joint strain diseases, often with numbness of the hands and feet as the main symptomatic manifestations, but also accompanied by local pain or stiffness and other manifestations.
(2) Drug factors: If the use of improper or overdose of isoniazid and other chemicals, as well as furazolidone, rifampicin, metronidazole and other antimicrobial drugs, can also be numbness of the hands and feet as a side effect.
(3) Nutritional deficiencies and metabolic disorders: severe deficiency of B vitamins in the body, chronic alcoholism, chronic gastrointestinal diseases and sequelae of surgery can also lead to numbness of the hands and feet.
Therefore, the causes of numbness of the hands and feet are diverse, and not always caused by peripheral neuropathy. If numbness occurs in the hands and feet and the symptoms cannot be relieved for a long time, one should consult a doctor in time to find out the cause of the disease and treat the cause of the disease.
