Possible causes of numbness of hands and feet

The physiological cause of numbness in the hands and feet often becomes exposure to air, or water with a low temperature.In this case, an emergency warming of the frozen limb is required.

Pathological causes of numbness

The most common reason for the sensations of dumbness in the hands and feet are diseases of the nervous system .Inflammatory changes in nerve trunks, infringements and other pathological processes often cause paresthesia.

Numbness occurs when:

  • Numbness polyneuropathy - multiple lesions of the trunks of the peripheral nervous system.In this case, numbness is accompanied by atrophies and weakness of the limbs( shrinkage), development of paresis( partial movement disorders) and even paralysis( complete loss of functions).Polyneuropathy occurs in diabetes mellitus, alcoholism and a wide range of other diseases, including infectious( diphtheria) blood diseases( hemoblastoses), hereditary( porphyria), connective tissue diseases( nodular periarteritis, systemic lupus erythematosus);
  • lesion of the nerve plexuses of the spine ( cervical, shoulder, lumbosacral).In this case, numbness is accompanied by pain.Painful areas are manifested in the corresponding dermatomes - zones innervated by certain plexuses.A common cause of numbness in the arms and legs is osteochondrosis;
  • stroke ( malnutrition of the brain departments).Especially with ischemic with developed paresis.At rest, patients often numb their arms and legs, tingling sensations, "skin fireworks";
  • syndrome of involvement of the median nerve ( with a round pronotor, carpal tunnel, etc.) Numbness in this pathology is combined with the characteristic feature of the "monkey brush".Paresthesia affects the palmar surface of 1 finger and the entire surface of 2-4 fingers;
  • pathological lesions of the radial and ulnar nerves ( Turner syndrome, etc.);
  • vascular pathology , especially in the case of the presence of obliterating endarteriosis - a disease in which blood circulation in the small arteries of the limbs is impaired as a result of their spasm.Numbness is characteristic of the clinical picture of osteochondrosis;
  • Reynaud disease - a paroxysmal impairment of blood circulation mainly in the area of ​​hands and feet.In this pathology, clear heredity and stress factors are traced;
  • hypovitaminosis .Most often, numbness is characteristic of the deficiency of B vitamins( B1 - thiamine, B12 - cyanocobalamin, B9 - folic acid).The lack of vitamin E also leads to problems with numbness in the hands;
  • vibration disease .Numbness and impaired circulation are common in people who constantly subject their body to vibrations with a constant amplitude.Constant microtraumatism and the formation of pathological reflexes cause painful manifestations;
  • shingles ;
  • Traumatic injuries ( broken arms and legs, bruises, dislocations) - can cause damage to the integrity of nerve fibers and terminations.These changes give a clinical picture of numbness;
  • taking certain medications.In this case we are talking about the side effects of drugs.These include certain types of antibiotics, chemotherapeutic agents.Therefore, before taking any medication, you should consult a doctor.It will be useful to read the attached instructions;
  • neuroses .

Note: neurological processes that cause numbness of the hands often occur in people engaged in specific activities that require constant stress of the hands, the humerus belt.Professions can be loosely related in character to each other.So, the seamstresses suffer seamstresses, violinists, pianists, people who spend a lot of time behind the computer keyboard, etc.
