Injury, infection, and chronic disease are serious causes of numbness or tingling in your hands and fingers.

The hands contain the most sensitive sensory receptors in the human body, and they are connected to the brain by a network of nerves. Even if a nerve is damaged or compressed, the brain does not receive the full sensory information. This results in uncomfortable numbness or tingling.

Dr. Rob Danoff, US physician from Aria Health, MD, spoke about the serious causes of neurological damage that contributes to numbness or tingling in the hands and fingers.

Epicondylitis If a person engages in activities that require repetitive twisting of the hand, wrist or elbow, they are at increased risk of developing epicondylitis or tennis elbow, a condition caused by the wear or weakness of the tendons that extend over the elbow. Its early signs are tingling and numbness in the hands, followed by pain in the elbow or forearm.

carpal tunnel syndrome
Pathology is common among people who spend a lot of time at the computer. Besides numbness and tingling in the hand, one or more fingers (usually the thumb, index and middle fingers) may feel swollen.

Thyroid diseases
An underactive thyroid gland – hypothyroidism – can damage the nerves that transmit information between the brain, spinal cord, and the rest of the body. This disease can also cause numbness or tingling in the hands and fingers.

Vitamin deficiency
Tingling in the hands is a serious sign of vitamin B12 deficiency, according to the doctor. It also has dangerously low levels of vitamin D, B6.

alcohol disorders
According to the US National Library of Medicine (NLM), long-term drinking can cause alcoholic neuropathy. Up to half of people who actively consume alcohol experience a disorder in one form or another. Symptoms include numbness in the arms or legs, pins and needles in the extremities, muscle weakness or cramps.

Guillain-Barré syndrome
It is an autoimmune disorder in which the immune system attacks nerves, causing damage that leads to numbness and tingling in the hands. Scientists do not understand exactly what causes the development of this syndrome, but it is known that it is often preceded by a respiratory disease, stomach flu. Other symptoms include weakness in the legs, unsteady gait, increased heart rate, and poor bladder or bowel control.

multiple sclerosis
Another autoimmune disease characterized by damage to myelin, a substance that acts as a protective sheath for nerve fibers in the brain and spinal cord. Women suffer from it two to three times more often than men. Besides hand numbness, MS also causes limb and muscle weakness, double vision, poor body coordination during movement, and pain.

brain attack
When combined with other symptoms, sudden numbness or tingling in the arm can be a sign of a person having a stroke, which occurs when blood flow to a specific area of ​​the brain is blocked. In order to timely identify the life-threatening violation of the cerebral blood supply, it is also necessary to pay attention to the following signs – a crooked smile, slurred speech, disorientation, dizziness, blurry vision.

Type 2 diabetes
It causes neuropathy or nerve damage in peripheral areas of the body. Besides numbness or tingling in the extremities, the person experiences extreme thirst or hunger, a frequent need to urinate, vision problems and kidney problems.
