Where Do Nerve Impingements Come From?
They are found in the cervical spine or lumbar spine (both the bones and the disc). Muscles can also impinge on nerves. An example of a nerve impinging on a nerve would be the piriformis on the sciatic nerve or the pronator teres pinching the carpal tunnel nerve. In the First rib, the nerve passes through the neck and forms the brachial plexus. The Brachial plexus passes through the first rib and into the arm. If the first rib is stuck, it can put pressure on the nerves. Important- We usually find that more than one structure is pushing on the nerve at a time.
