Scalenus posterior muscle pain refers to discomfort and pain in one of the deeper muscles of your neck. These muscles help support your head, aid breathing, and assist with neck movement. When they become strained, overused, or injured, pain can occur in your neck, shoulders, and sometimes even radiate to your arms.
Anatomy of the Scalenus Posterior Muscle
Understanding where the pain comes from means knowing a bit about the muscle itself. Here’s a simple breakdown:
Structure and Location
-
Location:
The scalenus posterior muscle is located deep in your lateral (side) neck. It lies alongside other scalene muscles that run from the cervical spine (neck bones) to the upper ribs.
Origin and Insertion
-
Origin:
It typically begins (originates) from the transverse processes (the small bony projections) of the lower cervical vertebrae (roughly C4 to C7). -
Insertion:
The muscle attaches (inserts) on the upper surface of the second rib. This connection helps in both neck movement and assisting in certain breathing actions.
Blood Supply and Nerve Supply
-
Blood Supply:
Small arteries such as the ascending cervical artery and sometimes branches like the dorsal scapular artery supply blood to the scalenus posterior muscle. This oxygen-rich blood nourishes the muscle. -
Nerve Supply:
The muscle receives signals from nearby cervical spinal nerves (often C5 to C8). These nerves control muscle movement and sensation in the neck and arms.
Key Functions of the Scalenus Posterior Muscle
-
Neck Stabilization: Provides support to the cervical spine during movement.
-
Assisting Lateral Neck Movement: Aids in bending the neck to each side.
-
Rotation of the Neck: Helps turn your head from one side to the other.
-
Facilitating Breathing: Works with other muscles to help lift the upper ribs during deep or labored breathing.
-
Supporting Posture: Contributes to holding your head and neck in a proper alignment.
-
Assisting Nerve and Blood Vessel Passage: Helps form the interscalene space, a passageway that allows essential nerves and blood vessels to travel from your neck to your arms and head.
Types of Scalenus Posterior Muscle Pain
The pain in this muscle can show up in various forms. Common classifications include:
-
Acute Pain:
Sudden pain resulting from a recent injury or strain. -
Chronic Pain:
Long-lasting pain that persists over weeks or months. -
Myofascial (Trigger Point) Pain:
Pain due to tight spots or “knots” in the muscle fibers. -
Referred Pain:
Pain felt in areas like the shoulder or arm, even though the problem is in the neck. -
Postural-Related Pain:
Pain associated with prolonged poor posture. -
Traumatic Pain:
Pain following an injury such as whiplash or a direct blow to the neck.
