When the weather is hot or the room temperature is high, my hands have been numb for a long time mainly on the fingertips. Ever since I was a child, if I touch something cold when I am numb, I will feel numb.

The causes

are as follows:

Peripheral neuritis

The peripheral nerves of the fingers are caused by poisoning, infection, vitamin B deficiency, and blood supply to the fingers. Obstacles and other reasons can cause inflammatory reactions, which can cause numbness and pain in the fingers. Most of the fingers of both hands occur at the same time, and can often be recovered after the cause is removed. Treatments such as oral administration or injection of vitamin B1, acupuncture, etc. can promote recovery.

Ulnar nerve damage

When the ulnar nerve in the forearm and upper arm is injured, compressed, or suffers from tumors, it can cause numbness and pain in the little finger and ring finger on the same side and partial finger movement impairment. The ulnar nerve groove at the back of the elbow is more susceptible to injury or compression. Most will gradually recover about half a year after the injury, but if there is a tumor, complete rupture, or severe compression, surgical treatment is often required.

Median nerve damage

The median nerve of the forearm and upper arm causes numbness and pain on the palm surface, thumb, index finger, and middle finger due to trauma, tumor, compression, etc. The wrist is most susceptible to injury or pressure, which is called carpal tunnel syndrome. The treatment principles are the same as before.

Radial nerve damage

The radial nerve is more susceptible to damage in the middle and lower sections of the outside of the upper arm, resulting in numbness and pain on the back of the thumb and index finger and drooping of the fingers and wrist. The treatment principles are the same as before.

Brachial plexus damage

Lesions or injuries in the axilla or front of the neck can cause mixed symptoms of total or partial damage to the ulnar, median, and radial nerves. The treatment principles are the same as before.

Cervical spondylosis

Due to the compression of cervical nerve roots or cervical spinal cord due to cervical hypertrophy and hyperplasia or cervical disc degeneration and herniation, it can cause unilateral or bilateral finger numbness and pain, and right finger numbness. Sometimes the entire arm to shoulder is numb and painful, making it difficult to hold a pen or knit a sweater. It is consistent with cervical spondylosis. The letter said that when the hand hangs down without exerting force, the hand will not be numb or painful. It means that after the right upper limb is relaxed, it is not compressed and the disease is relatively mild.

Treatment with traditional Chinese medicine

Finger numbness cannot be treated symptomatically, but the cause must be treated. No matter what the cause of finger numbness is, you should first go to the neurology department of the hospital for examination to determine the nerve. Is there any damage or any stimulation? If it is a neurological problem, electromyography is also required to further confirm the degree, scope, nature, etc. of the nerve damage. If the numbness of the hands and feet is caused by other reasons, the patient will be transferred to other relevant departments.

Diagnostic examination

For numbness of hands and feet caused by nerve damage, the choice of drug treatment or surgery should be based on the degree, scope, and nature of the nerve damage. Drug treatment is usually combined with acupuncture and physical therapy to promote rapid recovery. Surgical treatment is to divert the compressed nerves through surgery to achieve the purpose of relieving nerve compression and stimulation. The degree of cure depends mainly on the cause and nature of the neuropathy. If the peripheral nerves (nerves other than the brain and spinal cord) are injured, the recovery time is generally longer.

Daily care

As long as you exercise your neck and upper limbs appropriately, the numbness and pain in your fingers will gradually decrease. Exercise should be done step by step, do it gently first, then gradually strengthen it, and be sure to do it consistently. But beware of excessive or sudden strong movements. In addition, acupuncture, physical therapy, taking vitamin B1, etc. can be continued. If necessary, cervical traction and other treatments can be performed, but they must be carried out under the guidance of a physician.

[1] 1. Use both hands as much as possible

According to the theory that the left brain controls the right half of the body and the right brain controls the left half of the body, always using one hand can only stimulate the control of that hand. People with one side of the brain and left-brain dominance should strengthen the use of their left hand and left side of the body to stimulate the potential of the right brain, balance the relationship between the left and right brains, and enable coordinated development. Therefore, people who like to use their right hand should exercise their left hand more, such as using it to carry things, close windows and doors, turn pages of books, practice writing and drawing with the left hand, and work with the left hand. Left-handed people should exercise their right hand.

2. Develop finger flexibility

To enable fingertips to engage in more precise activities, such as assembling small plastic models, playing with small toys, sharpening pencils with a knife, etc. To enable the fingertips to engage in more precise activities.

3. Enhance the flexibility of the critical section

This is beneficial to improving the working efficiency of the brain. Such as stretching and flexing fingers, hanging elbows to write and draw, knitting sweaters, etc.

4. Exercise skin sensitivity

Skin insensitivity means that the sensory center of the brain is slow, so the fingers should often receive hot and cold stimulation, such as washing hands with cold or hot water. wait.

5. Diversify finger activities

Always monotonous methods will reduce finger flexibility and limit the information transmission between the brain and fingers. Various forms of finger activities can be performed, and a fitness ball can also be used to move the fingers if necessary.

It is important to note that numbness in the fingers may be a symptom of cervical spondylosis. The common treatment method for cervical spondylosis is to use traditional Chinese medicine similar to Jingfukang Granules. Finger numbness cannot be treated symptomatically, but the cause must be treated. Regardless of the cause of finger numbness, you should first go to the neurology department of the hospital for an examination to determine whether the nerves are damaged and what kind of stimulation they have received.

If middle-aged and elderly people have persistent thumb numbness, such as local pressure for too long or after a cold, some may feel like pinpricks, while others may feel heavy or numb. It subsides and will generally disappear on its own soon.

If the numbness lasts for too long or the symptoms gradually worsen, the patient will appear normal when going to the hospital, and there will be no special findings during the examination. The patient will often be diagnosed with neuritis or peripheral neuritis, and some B vitamins will be given orally or injected.

Preventive measures

Although some people can get better, some people have no improvement at all, especially after they reach middle-aged and elderly people. This is because middle-aged and elderly people have a problem. Numbness in the side thumb is often an ominous sign of stroke. When encountering this kind of situation, you should not be careless. You should go to the hospital to check your blood pressure, blood lipids, blood sugar and fundus. It is best to ask a neurologist for a detailed examination. Nip problems in the bud.

Hazard introduction

Finger numbness is an independent disease caused by damage to the motor nerves of the limbs. It is mostly caused by stroke, hemiplegia, diabetes, neuritis, cervical spondylosis, lumbar spondylosis, etc. The micro blood vessels around the motor nerve fibers are blocked, compressing the motor fibers, causing serious damage to the motor nerve fibers. The conduction ability and speed of the nerves decrease, and numbness occurs in the hands and feet. Severe cases can develop into painful symptoms such as limb paralysis and muscle atrophy.
