Thoracic nerve entrapment

The pectoral long nerve originates from the nerve roots of Neck 5, Neck 6, Neck 7, and innervates the serratus anterior. This nerve entrapment is rarely of concern to physicians. When studying the anatomy of the dorsal scapular nerve, the author found that most of the dorsal scapular nerve started from the cervical 5 nerve and the cervical 5 nerve from the thoracic long nerve. Sexual fibrous rings, so it is thought that the pectoral long nerve originating from the cervical 5 nerve may also be compressed together with the dorsal scapular nerve. Compression of the long chest nerve will produce clinical symptoms. There are obvious tender points on the neck and back, and pressing the tender points on the back can induce numbness in the forearm and fingers. The patient complains of discomfort and tingling in the left chest and left chest wall. And underarm discomfort, feeling from the back to the heart. After local neck closure, all symptoms disappeared.
