A pinched nerve, also known as nerve compression, can occur for a variety of reasons. Compression of a nerve in the neck or, less commonly, in the shoulder itself can trigger shoulder blade pain. Overuse, age-related changes and injuries are among the most common causes of this type of nerve compression. The signs and symptoms of a pinched nerve vary, and can occur intermittently or persistently.
