Cervical Brachial Syndrome or Cervicobrachial Syndrome is defined as neck and arm discomfort as a result of pressure on the brachial plexus. The brachial plexus is a group of nerves in the neck and shoulder region that sends nerve supply to the arms and hands.
Essentially, nerves in the neck branch off and web together creating the brachial plexus. Off of the spinal cord comes nerve roots, and these nerves branch into smaller and smaller nerves. For examples, branches of a C1-T1 nerve roots create the brachial and radial nerves, which in turn send some supply to the biceps and forearm muscles.
When there is clear impingement of nerves of the brachial plexus we call it Cervical Brachial Syndrome. The cervical part of the name refers to the fact that something in the cervical spine (the neck) is putting pressure on these nerves.
Symptoms of Cervical Brachial Syndrome
- Pins, needles, or numbness
- An “ache” or “burning” sensation in the arm
