Causes numbness in the fingers : index , nameless , little finger on the right or left hand

numbness of fingers - it's pretty bad, but is tolerable symptoms, which many do not pay attention.But there are some serious diseases that can cause loss of sensitivity.Although in most cases the causes numbness of the fingers are commonplace, you need to know all the possible states to begin a timely and competent treatment.

Causes numbness of fingers

not associated with the disease

    • Hypothermia
    • inconvenient pose during
    • sleep Exposure to chemicals
      • alcoholism
      • heavy metals and solvents
      • drugs

Pathological

tunnel syndrome Autoimmune processes Other
  • syndrome carpal tunnel
  • cubital tunnel syndrome
  • Guillain-Barre syndrome
  • scleroderma
  • syndrome Raynaud
  • Anemia
  • metabolic disorders (diabetes)
  • Spondylosis of the cervical spine
  • Avitaminosis
  • Progressive neurological disease (amyotrophic lateral sclerosis)
  • Infectious diseases (diphtheria)
  • Depression

Numbness is not associated with the disease

What are the reactions of the body are absolutely normal?(See. Why numb hands at night)

  • all know the feeling of "not his hands" when, during a sound sleep pinched one or both limbs.
  • The same thing happens if you "have pins and needles in one's arm" brush - onemeyut fingers.It is enough to a few minutes of normal position and intensity of the fist compression, to put everything in order.
  • During lose sensitivity as possible and when in the frost on the street, especially when working with water.

But if these situations are repeated every day, and always involve specific parts (for example, only numbness of the ring finger of the left hand), then you need to think about the causes of pathological.The only time the numbness is only one of the ring finger of the right hand is normal - too small a wedding ring.

tunnel syndrome

Carpal tunnel syndrome (carpal tunnel syndrome)

compression of the median nerve passing through the wrist, leads to carpal tunnel syndrome.It usually occurs in people of certain professions (musicians, programmers, packers), whose work is connected with the active bending arms at the wrists.Sometimes the syndrome occurs after injuries and surgical interventions, found it and swelling during pregnancy, as well as in patients with severe obesity.By the way, numbness in pregnancy does not require special treatment.

  • Signs of the disease include numbness, burning, tingling in the thumb, forefinger and middle fingers, sometimes spread all brush.
  • Deterioration takes place at night.
  • Prolonged compression of muscle weakness occurs and persistent nerve damage.

Diagnosis is mostly complaints, sometimes used MRI, electromyography and other advanced techniques.In order to treat the syndrome using anti-inflammatory medications, rest and tires in the areas of the wrists.Often you have to surgically to release the muscles and nerves from compression.When the first symptoms should see a doctor, as a slight numbness of the fingers may eventually turn into a disability.

ulnar tunnel syndrome

entrapment of the ulnar nerve all the way from the elbow to the wrist can cause a corresponding tunnel syndrome.The most frequent causes of such entrapment include:

  • habit to rely on your elbows while working and rest
  • injury
  • elbow strain (arthritis and arthrosis)
  • subcutaneous implant contraceptive
  • extensive bruising with blood diseases
  • unsuccessfulpuncturing a vein in the formulation of intravenous and taking blood
  • depletion with loss of muscle and fat mass
  • tumor
  • unexplained factors

signs elbow syndrome include burning, tingling and numbness in the little finger and ring finger.With the progression of pinching occurs weakness in fingers, pain, weight loss and muscle difficulties in manipulating hand.There is even a special feature: when you try to hide the brush in his trouser pocket the little finger is on the edge of the pocket.

diagnosis of ulnar tunnel syndrome, like carpal tunnel, is put on the complaints of the patient.It is necessary to eliminate the common causes of nerve lesion (diabetes), to investigate the elbow joint by X-ray or MRI, to recall the recent injuries and operations.With a slight numbness usually recommended to keep the hand constantly rectified, even in a dream.For this use the bus from soft tissues.If this does not help, and the weakness and atrophy of muscles increases, then resort to surgery.

numbness of fingers, extending to the entire limb or side of the body, especially in combination with slurred speech - a reason for emergency hospitalization.Such symptoms may indicate a stroke.

Raynaud

disease or Raynaud's phenomenon is conventionally divided into two types: primary (for no apparent reason and background diseases) and secondary.Last usually combined, and is the result of systemic autoimmune diseases (systemic lupus erythematosus, rheumatoid arthritis and others), and also occurs against the background of vibration in the workplace.The primary form is more often in younger women.The symptoms of Raynaud's phenomenon include:

  • numbness of fingers and toes
  • discoloration fingertips (pallor, why blue and eventually redness)
  • short-term changes
  • appearance in response to cold or emotional stress
  • in vibration disease numbspecific fingers, most exposed (thumbs, for example)

In primary Raynaud's disease is not a threat to life and health is only necessary to protect hands from the cold, vibration and avoid stressful situations.To exclude secondary form is necessary to consult a doctor.The diagnosis is usually made on the basis of complaints, but persistent changes, severe pain and the appearance of other additional methods used symptoms.

Examine the vascular bed (to prevent blood clot), nerve conduction (to avoid nerve disease), a blood test for the diagnosis of autoimmune processes.secondary forms of treatment begin with treatment of the underlying disease, and smoking cessation.From medicines used calcium channel blockers: nifedipine and similar preparations.In severe cases it is necessary to resort to surgery.

Anemia is very common nowadays condition is anemia.It manifests a variety of symptoms, which are often attributed to other diseases.In anemia, the blood hemoglobin level is lower than the established norm.Sometimes, hemoglobin is in the normal range, but the iron stores in the body is already exhausted.This is called latent (hidden) iron deficiency.

symptoms of anemia and latent iron deficiency:

  • numbness of fingers and toes
  • pale skin and mucous membranes
  • weakness, prolonged low-grade fever
  • aversion to meat, the propensity to inedible products
  • brittle hair, nails
  • itchy skin andxeroderma

believed that normal hemoglobin levels in men 20 to 59 years should not be lower than 137 g / l, men aged 60 - 132 g / l, and for women lower limit - 122 g / l.To determine the latent iron deficiency determine the level of ferritin in the blood.If confirmed anemia prescribed iron supplements (Ferretab, Sorbifer Durules see. Iron supplements for anemia), allowing the body to replenish the depot.


Guillain-Barre Syndrome

syndrome is an acute inflammation of the nerves and nerve roots, which resulted in impaired motor and tactile function.Often it is the numbness of the fingers and tingling sensation in them are the earliest symptoms of the disease.The signs of Guillain-Barre syndrome include:

  • numbness in the fingers and toes, rising up to the wrists and ankles
  • pain aching and pulsating character in the back, buttocks, thighs
  • fast or decrease in heart rate, shortness of breath
  • difficulty swallowing and speech
  • weakness in the legs and arms, up to the immobility

All symptoms usually appear after a short digestive disorders or lung SARS.The result is an autoimmune process in which the body attacks its own nerves.It develops disease sharply, reaching a maximum of 2-4 weeks.Then there is a gradual decline and attenuation of symptoms.

main treatment - rehabilitation after stopping the autoimmune inflammation.Recovery may be delayed up to several months.In severe cases (2-4%), death occurs from respiratory failure and other critical processes.But the majority of patients is only part of the above symptoms are manifested not in full measure.These people are good prospects for a full recovery of all body functions.

Scleroderma

One of the most severe autoimmune disease in which the skin, blood vessels, internal organs gradually compacted, losing elasticity, and its normal functions.This disease is not inherited, but the risk of ill relatives still above average.Most often, the disease affects women aged 30-50 years.Its causes are unknown.

Symptoms of scleroderma:

  • skin seal (starts with the fingers), numbness and tingling
  • disappearance of wrinkles
  • face the appearance of dark and light spots on the skin, luster sealing regions
  • appearance of small petechial hemorrhages in the skin
  • numbnessfingers and other lesions, Raynaud's phenomenon
  • pain in muscles and joints
  • shortness of breath, increasing respiratory distress
  • digestive disorders
  • decreased vision
  • inability to open his mouth wide, hoarseness

For diagnosis is usually sufficient to cast patient eye.But often use blood tests (general, biochemical analysis to autoantibodies) to confirm the presence of the disease.If in doubt, conduct a biopsy of the affected area of ​​the skin, which is then examined under a microscope.

symptomatic treatment of the disease, that is directed to the removal of the major signs of the disease.Use anti-inflammatory drugs, mokrotorazzhizhayuschie agents, laxatives, steroids and other drugs.In addition, it is very important a balanced diet, avoiding harmful habits, work in cold conditions, timely treatment of wounds and ulcers.

addition scleroderma cause nerve damage and numbness of the fingers may be almost any autoimmune disease.Therefore, the therapist will, if necessary, referral to a rheumatologist to exclude immune failure as the cause of numbness.

Some psychological problems (depression, for example) may be masked by unpleasant sensations in the hands and feet.They are often limited to the fingers.Therefore, if in addition to numb hands have complaints of sweating, rapid pulse, insomnia, causeless tears and a sense of longing, then an urgent need to see a specialist.Depression - is a very serious disease that requires adequate treatment drugs.

effects of alcohol Alcohol

, in addition to many other serious disorders cause neuropathy in humans (ie, nerve damage).There is even a special term: Alcoholic neuropathy.It is connected with the versatile influence of ethanol.It prevents the absorption of essential substances such as thiamine, proteins folates.In addition, ethanol derived directly affect the nerves, causing their destruction.In the liver, there are also injuries that indirectly act on the neuromuscular transmission.Thus, numbness of the fingers in alcoholics - a phenomenon quite common.

poisoning by heavy metals and chemical substances

in different industries using chemical compounds that have a negative impact on the entire body, including the nervous system.Therefore, people who work in industry, construction, paint shops, often in contact with these dangerous substances.Numbness of fingers may cause arsenic, lead, mercury, thallium, solvents.In addition, the symptom may have problems with digestion, breathing, and even impaired consciousness.Therefore, if after exposure to a hazardous substance came of the above symptoms, you should immediately seek medical attention.

Medicines Some medicines can cause numbness in the extremities, including fingers.These include isoniazid (anti-TB drug), vincristine (antineoplastic drug), gold compounds, some means of AIDS, metronidazole.Typically, the annotations to the drugs have a list of side effects that should be taken into account by the doctor.

Diabetes

In type 1 diabetes onset is associated with a sharp deterioration in health, and only after many years of illness arises nerve damage.Type 2 diabetes is more insidious, it can proceed malosimptomno, at the time of setting the diagnosis in humans may already be neurological symptoms.In addition, irregular medications and poor control of blood glucose lead to inevitable consequences.The most famous of them - "diabetic foot" with the loss of sensation in the feet of the formation of ulcers.But quite often there are disorders of the nervous tissue in the hands, resulting in numb fingers or whole brush.

Symptoms of diabetic neuropathy of hands:

  • numbness and tingling fingers
  • worse at night
  • often affects both hands, but there are violations in one limb or several fingers (eg, numbness, index fingers)

To diagnose diabetesneuropathy primarily to confirm diabetes.To this end, define the glucose level, glycated hemoglobin in blood was examined urinalysis.Sometimes diagnose vascular and nerve in the fundus of the eye, heart and other organs.To control this condition is necessary to maintain adequate levels of glucose, using special hypoglycemic agents or insulin injecting on doctor's orders.If accurately implement all the recommendations, do not run the disease, it is possible to avoid both unpleasant symptoms and severe complications.

Spondylosis

gradual destruction of the intervertebral discs in the cervical spine, their protrusion formation of sharp edges - this is an inevitable process, called spondylosis.As disks wear can be formed pain in the neck, shoulder, hand, limitation of movement and sensitivity.Numbness usually occurs in the arm or hand, but sometimes it affects only the fingers.Diagnosis is made on the basis of CT and MRI.Treatment typically includes anti-inflammatory agents, antispasmodics, massage and physiotherapy.If the image is too large herniation or spinal canal narrows, the operational methods used.

Lack of vitamin B1 (thiamine)

Thiamine deficiency in the body can cause unpleasant consequences for health.The disease, which arose as a result of vitamin deficiency, called beriberi.Primarily there disorders of the nervous system.In severe cases, it damages the heart and the entire cardiovascular system.


Symptoms B1 deficiency:

  • bilateral numbness of fingers and toes, which has a tendency to spread
  • muscle cramps
  • atrophy (weakening, shrinkage) of muscles
  • memory loss, insomnia
  • Wernicke's encephalopathy and Korsakoff syndrome (violation of the brain with the emergence of a mental disorder)
  • severe weakness in the legs
  • rapid pulse
  • low blood pressure, fainting
  • digestive disorders

Severe cases of beriberi in the developed countries are rare, mainly for the following reasons:
