After waking up in the morning, the fingers or even the whole arm will feel numb, is a lot of older people or young people will have the experience, some people do not care much, thought it is sleep pressure numb. The sensory nerves of the fingers are the nerve roots from the cervical spinal cord, which form the brachial plexus nerve in the cervical axilla, and then the radial nerve, median nerve, ulnar nerve, etc. through the upper arm and forearm, becoming the unperipheral nerves distributed to the hand and fingers. When injury, inflammation, tumor, pressure, etc. occur in these areas of the nerve, causing abnormal sensation, numbness and pain in the fingers will occur. There are several common diseases that cause numbness and pain in the fingers: a. Peripheral neuritis The peripheral nerves of the fingers can produce numbness and pain in the fingers due to inflammation caused by poisoning, infection, vitamin B deficiency, and impaired blood supply to the fingers. Most of the fingers of both hands occur at the same time, and often recover after the cause is removed, oral or injectable vitamin B1, acupuncture and other treatments can promote recovery. Ulnar nerve damage When the ulnar nerve in the forearm and upper arm is traumatized, compressed, or tumor-bearing, it can cause numbness and pain in the little finger and ring finger on the same side, and some finger activities can be impaired. The ulnar nerve sulcus at the back of the elbow is more likely to be damaged or compressed. Most of them will recover gradually about six months after the injury, but surgery is often required for tumors, complete rupture or severe compression. Median nerve damage The median nerve in the forearm and upper arm is caused by trauma, tumor, compression, etc., causing numbness and pain on the palmar surface, thumb, index finger and middle finger. It is most likely to be damaged or compressed at the wrist, called carpal tunnel syndrome. Treatment principles are the same as before. Radial nerve damage The radial nerve is more likely to be injured in the middle and lower part of the upper arm, resulting in numbness and pain on the back of the thumb and index finger and finger and wrist droop. Treatment principles are the same as before. V. Brachial plexus nerve damage Lesions or injuries in the axilla or anterior cervical region can cause mixed symptoms of total or partial damage to the ulnar, median and flexor nerves. Treatment principles are the same as before. Sixth, cervical spondylosis Due to cervical hypertrophy and hyperplasia or cervical disc degeneration and herniation, etc. compression of cervical nerve roots or cervical medulla, it can cause unilateral or bilateral finger numbness and pain, and gradually develop to the upper arm, forearm, and even upper limb movement disorders. Recently, someone wrote to describe numbness and pain in the fingers of the right hand, and sometimes the whole arm to the shoulder is numb and painful, and it is difficult to hold a pen or knit a sweater. This is consistent with cervical spondylosis, and the letter says that when the hand is lowered without force, the hand is not numb or painful. Indicates that the right upper limb is not compressed when relaxed, and the lesion is still mild. Treatment of numb fingers Finger numbness cannot be treated symptomatically, but rather the cause of the disease. Regardless of the cause of the numbness of the fingers, you should first go to the neurology department of the hospital for an examination to determine whether there is damage to the nerves and what kind of stimulation has been suffered, and if the problem is neurological, an electromyography examination is also required to further confirm the degree, extent and nature of nerve damage. If the numbness is caused by other reasons, the patient will be referred to other related departments for treatment. For nerve injury-induced numbness, the choice of medication or surgery is based on the degree, extent, and nature of the nerve injury. Medication is usually used in conjunction with acupuncture and physical therapy to promote rapid recovery. Surgical treatment is to surgically divert the compressed nerve to relieve the nerve from compression and irritation. The degree of healing depends on the cause and nature of the neuropathy. In the case of peripheral nerve damage (nerves other than the brain and spinal cord), recovery time is usually longer. The numbness of the fingers is an independent disease of the limb motor nerve damage, mostly caused by stroke hemiplegia, diabetes, neuritis, and cervical and lumbar spondylosis, etc. The microscopic blood vessels around the motor nerve fibers are blocked, compressing the motor fibers, resulting in serious damage to the motor nerve fibers, and the conduction ability and conduction speed of the nerve decreases, resulting in numbness of the hands and feet. Severe cases can develop into limb paralysis, muscle atrophy and other tragic symptoms. Daily care of numb fingers As long as the appropriate exercise neck and upper limb activities, will gradually make the finger numbness and pain will be reduced. Exercise should be done gradually, first gently, and then gradually strengthen, and be sure to insist on doing. But to prevent excessive or sudden too strong movements. In addition, acupuncture, physical therapy, taking vitamin B1, etc. can be continued, and cervical traction and other treatments are feasible if necessary, but only under the guidance of a physician. In the case of persistent numbness of the thumb in middle-aged and elderly people, such as after prolonged local pressure or cold, some are like pins and needles, while others feel heavy or hypoesthesia, which will generally disappear on its own soon. If the numbness persists for a long time or if the symptoms gradually worsen, when you go to the hospital, you can see that the appearance is normal and there are no special findings in the examination, so you are often diagnosed as neuritis or peripheral neuritis and given some B vitamins orally or by injection. Although some people can improve, but some people are no improvement, especially after the middle-aged and elderly people are more like this, because the middle-aged and elderly people appear numbness of one side of the thumb, often is the ominous signs of stroke, encounter this situation, not paralyzed, should go to the hospital to check blood pressure, blood lipids, blood sugar and fundus, it is best to also go to the neurologist for a detailed examination to prevent problems before they occur.
