Brachial plexus neuralgia is a condition that produces pain within its innervation when various parts of the brachial plexus nerve, which consists of the anterior branches of the nerves from cervical 5 to thoracic 1, are damaged. It mainly innervates the sensation and movement of the shoulder and upper extremities. The pain that occurs within the innervation of each of the brachial plexus nerves is called brachial plexus neuralgia. Pain in the scapular girdle and upper extremity is one of the main symptoms of primary brachial plexus neuralgia, or brachial plexus neuritis. What are the common causes of scapular girdle and upper extremity pain? Primary brachial plexus neuralgia can be divided into two categories: primary and secondary. The cause of primary brachial plexus neuralgia is unknown and may be a metabolic disease, with occasional familial cases seen in mild trauma vaccination, degree of systemic infection secondary brachial plexus neuralgia brachial and plexus adjacent lesion compression, i.e. nerve root compression (cervical spondylosis disc prolapse tuberculosis tumor fracture dislocation, cervical medullary tumor and arachnoiditis, etc.) and nerve trunk compression (thoracic outlet syndrome, cervical rib or cervical tumor axillary lymph node enlargement (metastatic carcinoma), clavicle fracture pulmonary sulcus tumor according to the site of their lesions can be further divided into radicular brachial plexus neuralgia and dry brachial plexus neuralgia causes of radicular brachial plexus neuralgia, there are various lesions of the cervical spine cervical medullary tumor epidural metastatic carcinoma and other causes of dry brachial plexus neuralgia, there are cervicothoracic outlet area syndrome brachial plexus neuritis cervical tumor traumatic tuberculosis pulmonary apical tumors, etc. In the acute stage, it is advisable to reduce activities and lift heavy objects, so that the limb can rest properly, you can use a triangular towel or bandage to suspend the affected limb in front of the chest, so that muscle tension can be eased, which helps to reduce pain, keep emotional stability to avoid mental tension, reduce mental stress, establish confidence to overcome the disease, and actively cooperate with treatment. Pay attention to keep warm, prevent the invasion of cold, living environment should be ventilated, fresh air, sufficient sunlight, indoor temperature, humidity should not be too high, to prevent cold and flu. Ask the patient to rest more, and enhance physical exercise, such as taijiquan, radio exercises, etc. Exercise must be different from person to person and from disease to disease, stop as appropriate, and act according to ability.
