What Are the Nerves of the Arm?

After the brachial plexus is sent from the cervical spinal cord, it passes through the corresponding intervertebral ligament to form a neural trunk and is distributed in the upper limbs. Pain in the neck, shoulders, upper arms, forearms, and hands caused by damage to the brachial plexus nerve is called brachial neuralgia.

Brachial neuralgia

Brachial plexus nerve from neck

It often occurs in middle and old age, with slightly more men. Brachial neuralgia is caused by cervical osteogenesis and intervertebral disc disease stimulating and compressing the brachial plexus nerve root. Often after fatigue and cold, symptoms appear as pain in the neck and shoulders, radiation to the upper arm, forearm, fingers and forearm, with paroxysmal aggravation on the basis of persistent pure pain. The pain resembles a knife cut, acupuncture, or fire. The neck may have a strong feel. The pain becomes worse when the neck is bent or stretched to one side excessively, or when the top of the head is pressurized, or when sneezing or coughing. When you rest in bed and pull your head up, you can reduce the pain. The affected upper limb often has numbness and acupuncture-like sensations, the skin's ability to sense acupuncture, touch, and heat and heat slightly diminishes, and the muscles of the upper limbs may slightly atrophy. X-rays of the cervical spine can assist diagnosis.

To prevent this disease, you should start from a young age, strengthen physical exercise, strengthen your physique, pay attention to cold and warm, prevent the progressive aging of the cervical spine, treat bed rest, keep the affected limb warm, take painkillers and muscle relaxants internally, do cervical traction under the guidance of a doctor, and then Wear a cervical collar. Other applications such as acupuncture, massage and massage can also be selected.

Onset of colds or colds, adults and men are prone to the disease, and the onset is faster. First, they feel pain at the base of the neck and upper clavicle, and soon spread to the back of the shoulder joint. They spread to the arms and hands after a few days. The pain resembles fire, acupuncture or soreness begins to be intermittent pain, and it is passed on to persistent pain soon, with paroxysmal aggravation. When the arm is raised forward or outward, it can be caused by pulling the nerve. The pain worsened. In order to reduce pain, patients often avoid the movement of the upper limbs, and adopt a posture of flexing the elbow joint, or often change the posture of the upper limbs, and lie more to the healthy side when sleeping. On the clavicle, there can be obvious pressure disease in the lower socket, axillary and other places. Within a few days of onset, the upper extremity felt weak. Within weeks, muscles may atrophy. Upper limbs' perception of pain, temperature, and touch is reduced. A small number of patients may experience sweating or no sweating, thin and shiny skin, thickened nails, and inequality.

Treatment should first rest the affected limb, flex the elbow, close to the chest, and suspend it on the neck with a wide cloth band to reduce pain. In the acute phase, adrenal cortex hormones, analgesics, and B vitamins can be used, and in combination with traditional Chinese medicine, acupuncture,

After the brachial plexus is emitted from the spinal cord, it passes through the space formed between the cervical spine, the clavicle and the anterior oblique muscle, and is distributed to the upper limbs through the axilla. Brachial plexus neuralgia can occur when there is a congenital abnormality in the cervical spine, such as a long transverse process, or abnormal development of the cervical ribs or anterior oblique muscles. Women above middle age are susceptible to the disease. Symptoms gradually develop. To the right more. In mild cases, there is periodic pain in the shoulder swelling area, which radiates downward to the inside of the arm. In severe cases, the pain resembles drilling or burning. It is located behind the scapula, radiating to the side of the neck, and radiating down to the inside of the upper arm, forearm and palm. May be accompanied by numbness and acupuncture on the ulnar side (little finger side) of the upper limbs. Pain can be exacerbated when lifting, carrying or lifting. The pain can be reduced by placing your arms close to your chest or raising your hands above your head. Severe cases include weakness of the affected limb and muscle atrophy. Brachial plexus nerves and arteriovenous supplies to the upper limbs. If blood vessels are compressed at the same time, chills, paroxysmal paleness, and bruising can occur. When the limb is overextended and abducted, the radial artery pulsation weakens or even disappears. In some patients, bulges and bony masses can be seen on the neck, this is the cervical ribs. X-rays can confirm cervical ribs or other bone deformities.

Treatment can use a sling to assist the flexion of the affected limb and slightly raise the shoulder. Take appropriate rest, take painkillers orally, or take acupuncture, cupping, massage or physiotherapy. Severe patients should be hospitalized for surgical treatment.
