The sensory nerve of the finger is the nerve root branching from the cervical spinal cord, forming brachial plexus nerve at the cervical axil, and then branching into radial nerve, median nerve, ulnar nerve and so on. It passes through the upper arm and forearm and becomes the peripheral nerve distributed to the hands and fingers. Numbness of fingers will appear when nerve injury, inflammation, tumor, oppression, etc. Cause abnormal feelings in these parts.

Diseases that cause finger numbness are as follows:

Peripheral neuritis

Finger peripheral nerve can cause finger numbness due to poisoning, infection, vitamin B deficiency, finger blood supply disorder and other reasons. Most fingers of both hands occur at the same time, and they can often be recovered after resection. Oral administration or injection of vitamin B 1, acupuncture and other treatments can promote recovery.

Ulnar nerve injury

When the ulnar nerve of the forearm and upper arm is injured or compressed, or suffers from tumor, it can cause numbness of the little finger and ring finger on the same side and some finger movement disorders, especially at the groove of ulnar nerve behind elbow. Most of them will gradually recover about half a year after injury, but if they have tumors, complete fractures or severe compression, they often need surgery.

Median nerve injury

The median nerve of forearm and upper arm is numb in palm, thumb, forefinger and middle finger due to trauma, tumor and compression. Wrist is the most vulnerable to injury or compression, which is called carpal tunnel syndrome. The treatment principle is the same as before.

Radial nerve injury

The middle and lower segment of the lateral upper arm is easy to damage the radial nerve, resulting in numbness on the back of thumb and forefinger and drooping fingers and wrists. The treatment principle is the same as before.

Brachial plexus injury

Injury or injury of axillary or anterior neck can lead to mixed symptoms of total or partial injury of ulnar nerve, median nerve and flexor nerve. The treatment principle is the same as before.

cervical spondylopathy

Compression of cervical nerve root or cervical spinal cord due to cervical hypertrophy and hyperplasia or cervical intervertebral disc degeneration and protrusion can cause numbness of one or two fingers, numbness of the fingers of the right hand, and sometimes numbness and pain of the whole arm, making it difficult to hold a pen and knit a sweater. In line with the situation of cervical spondylosis, the letter said that when the hand droops, it will not be numb or painful without exertion. It means that the right upper limb is not compressed after relaxation, and the lesion is still light.

Chinese traditional treatment

Finger numbness cannot be treated symptomatically, but the cause should be treated. No matter what causes finger numbness, you should first go to the neurology department of the hospital to check whether there is nerve damage and what kind of stimulation you have received. If it is a neurological problem, electromyography is needed to further confirm the degree, scope and nature of nerve injury. If the numbness of hands and feet is caused by other reasons, then transfer to other related departments.

Daily nursing

As long as the neck and upper limbs are properly exercised, the numbness of fingers will gradually be alleviated. Exercise should be gradual, first gently, and then gradually strengthened, and we must persist in doing it. But to prevent excessive or sudden strong movements. In addition, acupuncture, physical therapy, taking vitamin B 1 etc. Can continue, if necessary, cervical traction and other treatments are also feasible, but under the guidance of a doctor.
