Numbness of the hands and fingers - Carpal tunnel syndrome

Numbness of hands in the form of stinging, burning, tingling or numbness in medicine is known as paresthesia and can affect the palms, backs and fingers, and is considered normal if it does not last longer than a few minutes. Depending on the cause, loss of sensation in the hands may be short-termed, often occurs at night and tingling of hands happens when you sleep on your hand with a bent elbow or wrist, but sometimes it occurs suddenly and develops gradually. If the numbness of the hands does not withdraw even after a few hours, or even becomes chronic, it is necessary to consult a doctor because it may indicate a more serious illness and lead to a permanent loss of feeling in the hands and fingers.

Tingling of fingers; CAUSES

The nerves carry signals from different parts of the body to the brain and vice versa, and tingling of hands is commonly associated with their damage. Reduced blood flow, any kind of pressure or clamp on nerves causes numbness in certain parts of the body, whose causes are numerous - poor circulation, age and certain diseases. Already in the first manifestation of symptoms it is necessary to determine whether they are functional or organic changes and whether it is a transient symptom in a state of high nervous tension.

Carpal Tunnel Symptoms

Carpal tunnel syndrome is caused by pressure on the central nerve (median nerve) in the area of ​​the carpal tunnel (canalis carpi). Carpal tunnel consists of eight small bones on the underside of the wrist, and a channel on the upper side closed with transverse carpal ligament. Through this "pipe" from the forearm into a fist enters the central nerve and tendon muscles responsible for moving the fingers and they are coated with a thin membrane that lubricates them and makes the movement much easier. They are sensitive to prolonged strain and irritation.

Carpal tunnel syndrome in pregnancy

Numbness of fingers in pregnancy, tingling, pain in hands are a result of carpal tunnel syndrome. Most pregnant woman face a mild swelling of the arm that is caused by the accumulation of water in the tissues. Swollen area makes pressure on central nerves and causes numbness of hands and fingers and about 60% of future mother suffers from this syndrome. Carpal Channel symptoms appear between the second and third quarters, and disappear soon after giving birth. Read a mandatory text; diet during pregnancy.

Numbness of arms; OTHER CAUSES

Numbness of arms, hands and fingers can be caused by diabetic neuropathy (nerve damage caused by diabetes), from which suffers about two-thirds of patients. If not brought under control, it can cause vascular damage, which sometimes requires amputation. Numbness in the arms can be caused by migraines, arthritis, multiple sclerosis, radiculopathy (sciatica), autoimmune diseases, infections, exposure to radiation, certain chemicals and heavy metals, excessive alcohol consumption and cigarette smoking, frostbite, bites of animals and insects, seafood and certain medications. For this syndrome the most responsible is heavy physical activity, a particular move or action at the level of the wrist (usually with typists or people who work at the computer for a long time), and pregnancy and hormonal disorders.

Numbness of arms and pinched nerves – Cubital Tunnel Syndrome 

It occurs as a result of ulnar nerve getting pinched in the elbow. From the inside of the elbow, a between a small bony bumps and the last part of the elbow bone, there is a narrow cavity with a membrane that is stretched between the mentioned bones to form the elbow or cubital tunnel. Through it ulnar nerve passes from the upper arm into the forearm. Pinched nerve is manifested as pain, numbness of hands or decrease sensitivity to the inner side of the hand, the little finger and the inner half of the ring finger has a weakened hand grip. Pinched nerve is most often caused by a thickening of the membrane or a break of a small bone crest.

Symptoms of peripheral neuropathy

This acute or chronic damage to nerves of the peripheral nervous system (primarily the myelin sheath of nerve fibers) is the result of inflammatory or autoimmune process which causes numbness of an arm or a loss of sense of touch in the body under the control of the affected nerve. If peripheral neuropathy is not kept under control, it can extend to large groups of muscles and organs.

Tingling in your hands and cervical spondylitis

Cervical spondylitis is a degenerative disease of the cervical spine, and the process of decay affects vertebrae, discs, ligaments and wrists. Degenerative changes are the result of aging (resulting in the forties and are more common in men), improper posture, and certain medical and hormonal disorders, such as diabetes, osteoporosis, osteopenia and tumor of bones. Pinching of cervical nerves is accompanied by limited mobility of the upper extremities, numbness, pain and numbness of the hands and fingers.

Raynaud's syndrome, and numbness of fingers

This syndrome is a disease of blood vessels, and occurs due to cramps and blockage of blood flow to the fingers. Between 3% and 20% of the adult population suffers from Rejnoovog syndrome, which mainly affects women. Hand numbness and coldness in the fingers occurs, even when the outside temperature is pleasant, it can indicate Raynaud's syndrome.

Poor circulation and numbness of the hands

Complete blockage or insufficient blood flow to the hands and fingers causes numbness of hands and stiffness. In cases of severe forms of arrhythmia, the heart is unable to pump a sufficient blood, which impairs its flow to the vital organs such as the brain and extremities, resulting in ischemia (narrowing of blood vessels) and tissue death.

Numbness of hands and stroke

A sudden interruption of blood flow to parts of the brain that control motor activity of arms can also cause numbness in the fingers and hands. First symptoms of stroke occur in the form of mild ischemic changes such as tingling and numbness in the hands, and if we do not respond in time, it can come to a complete loss of mobility.


Numbness of the hands and fingers is sometimes the result of lack of nutrients – calcium (hypocalcemia), magnesium, zinc and vitamin D and B12.
Tingling in your hands - HOW IS IT DIAGNOSED

The diagnosis is often sufficient with a detailed neurological examination, but if there is a suspicion on a specific disease, carried out is x-ray examination, computed tomography (CT), magnetic resonance imaging or electromyoneurography (EMG). Blood tests determine the presence of toxins or infections that affect the nervous system. In the examination reveals also disorders in the nervous system, whether they are central (at the level of the brain) or peripheral nerve damage.

My hands are numb - WHAT IS THE BEST THERAPY?

Access to the treatment depends on the causes of the problem and sometimes requires the engagement of the entire team of specialists: neurologists, radiologists, physiatrists, endocrinologists, orthopedists, cardiologists, rheumatologists. For numbness of hands frequently is applied physical therapy, body massage, drugs, and if necessary, surgery. If the numbness of fingers is associated with diabetes, it is necessary to regularly control the level of sugar in the blood, while the lack of vitamins and minerals is compensated with appropriate supplements. A diet rich in fiber and antioxidants, lowers cholesterol and improves circulation, making it easier problems. Yoga and meditation also have a beneficial effect on nerves and when the numbness of the hands is caused by certain drugs, you can in consultation with the doctor, replace or stop their use.
