Suprascapular pain is typically described as a dull, aching, or burning pain located in the posterolateral shoulder, which may extend to the neck or down the arm on the same side of the body. This pain is often linked to an injury affecting the suprascapular nerve at the suprascapular notch.
Characteristics of Suprascapular Pain:
- Location: Primarily felt in the back and side of the shoulder.
- Quality: Often described as dull, aching, or burning.
- Radiation: Pain may spread to the neck or upper arm.
- Aggravation: Overhead shoulder movements can worsen the pain.
Cause of Suprascapular Pain:
Suprascapular pain is often caused by compression or injury to the suprascapular nerve as it passes through the suprascapular notch, a bony structure located on the upper edge of the scapula (shoulder blade). This nerve supplies motor function to the supraspinatus and infraspinatus muscles (important for shoulder movement and rotation) and sensory information from parts of the shoulder joint.
Contributing Factors:
- Repetitive overhead activities: Sports like volleyball, baseball, and weightlifting can increase the risk.
- Direct trauma: A blow to the shoulder can damage the nerve.
- Anatomical variations: Some individuals may have a smaller suprascapular notch, predisposing them to nerve compression.
- Cysts or masses: Rarely, these can compress the nerve.
Diagnosis and Treatment:
A thorough physical exam, including specific tests to assess the suprascapular nerve, is crucial for diagnosis. Imaging studies like MRI may be used to visualize the nerve and surrounding structures. Treatment options range from conservative measures like rest, physical therapy, and pain medication to surgical decompression of the nerve in more severe cases.
In summary, suprascapular pain is a specific type of shoulder pain resulting from irritation or compression of the suprascapular nerve, causing a dull, aching discomfort in the back and side of the shoulder, often aggravated by overhead activities.
