What is Cervical Foraminal Stenosis?

Essential facts and insights about Cervical Foraminal Stenosis

Key Clinical Considerations:

Neck pain radiating to the arms
Numbness or tingling in the upper extremities
Weakness in the arms or hands
Key diagnostic tests include MRI or CT scans showing foraminal narrowing
Physical exam may reveal decreased reflexes or muscle strength in the upper extremities

Clinical Information
