Pain in the scapular girdle and upper extremities is one of the main symptoms of primary brachial plexus neuralgia, or brachial plexus neuritis. Brachial plexus neuralgia is a condition that produces pain within its innervation when the various parts of the brachial plexus nerve, which consists of the anterior branches of the nerves from cervical 5 to thoracic 1, are damaged. So what are the clinical manifestations and tests for scapular girdle and upper extremity pain symptoms? Intercostal scapular girdle pain: A herniated intervertebral disc can cause intercostal scapular girdle pain by squeezing the spinal nerve roots at the outlet of the radiculopathic nerves. Intercostal scapular girdle pain is a clinical manifestation of thoracic disc herniation. Scapular pain: The scapula is also called scapula and pipa bone. Located at the back of the thorax, it is a triangular flat bone between the 2nd and 7th ribs. Scapular soreness is caused by muscle spasm and deformation for a long time. It can also be a consequence of chronic muscle inflammation often caused by a prolonged posture. Scapular radiating pain: i.e., the pain is radiating, and the radiating pain radiates from the proximal end of the limb (near the side of the heart) to the distal end of the limb as if it were a string of electric sensations. This means that the lesion does not occur in the limb itself, but in the spinal cord centers of the cervical, thoracic, and lumbar regions or in a large nerve center or nerve cadre. Radiating pain in the upper limb indicates a lesion in the plexus of the neck or shoulder. Rest the limb properly, minimize the movement of the diseased limb, flex the forearm and suspend it in front of the chest. If it is caused by cervical spondylosis, pay attention to the head position should not be fixed for too long, the lying pillow should not be too thick, to avoid excessive neck flexion. Diagnosis and treatment should be based on its clinical manifestations, neurological examination of selective shoulder and cervical spine X-ray radiographs, cerebrospinal fluid laboratory tests, electromyography, upper extremity hemograms, nerve conduction velocity, cervical spine CT or MRI examination.
