Why is the man's left hand numb?

Some people will feel numbness in their limbs without realizing it, and some people will feel numbness in their limbs and feel powerless when they wake up from sleep. If you find that your arm is numb, it is one of the common arm diseases. This is a reminder of the nerves. Pay attention to the diagnosis and treatment immediately, otherwise it will bring inconvenience to life. So what is the reason for the sudden numbness of the right hand?

What causes sudden numbness in the right hand?

1. Wrong sleeping posture, long-term compression of the arms, resulting in insufficient blood supply, which can easily cause numbness in the hands. Sometimes this condition is nothing to worry about.

2. Cervical spondylosis. If you keep lowering your head in the same position, it is likely to cause radicular cervical spondylosis, which compresses the nerves and causes insufficient blood supply to the head and body, weakened muscle tone and muscle atrophy, causing short-term dizziness and numbness in the hands. It is common in the middle-aged and elderly. It is recommended to go to the hospital for an outpatient X-ray of the cervical vertebrae for diagnosis, do more neck exercises, and sleep with the pillow at a height of 7 to 9 cm at night. The sleeping posture should be appropriate to prevent some blood vessels and nerve tissues from being compressed.

3. Cubital tunnel syndrome. The nerve is compressed at the elbow, which is the so-called "cubital tunnel syndrome". It is usually characterized by reduced support of the ring finger and little finger of the right hand, and symptoms such as arm fatigue, reduced forward flexion in sitting, clumsy arm movements, and grasping loose objects. The patient will continue to be awakened by numbness at night, and it is difficult and inflexible to grasp things with the hands.

4. Shoulder pain caused by periarthritis of the shoulder causes numbness in the hands. Long-term lack of exercise causes shoulder pain, which can cause sudden numbness or pain in the arms. Or damage to the Jianjing acupoint can cause shoulder pain, headache, dizziness, and hand pain. Since the shoulders control both sides of the body, why not try massaging the Jianjing acupoints if you have numb hands?

5. If the elderly have poor digestion and malnutrition for a long time, it will cause vitamin B21 deficiency, leading to peripheral neuritis and numbness of fingers.

6. High blood pressure can cause vascular spasm, high blood lipids can increase blood viscosity, and the blood flow is slow during sleep at night. These factors can cause transient cerebral ischemia and cause finger numbness. Pay attention to eliminate the three high risks.

7. Numbness of the limbs or half of the face, unsteady posture, slurred speech, etc. caused by a stroke are all precursors of a stroke. Please seek medical attention immediately.

In short, if your right hand suddenly becomes numb, it is recommended to go to the hospital for outpatient neurology consultation to see if the nerves are damaged or stimulated. It is necessary to take a cervical vertebrae X-ray and electromyography for diagnosis. If you receive timely treatment, you will get better. Usually, you should stand up and walk around after sitting for a long time, move your head and shoulders, and flex and stretch your hands more to keep the blood flowing.
