A herniated cervical disc occurs when the gel-like nucleus pulposus ruptures through the annulus fibrosus in the cervical spine. It commonly occurs at the C5-C6 or C6-C7 levels. Symptoms may include neck pain radiating into the arm with numbness/tingling. Diagnosis involves MRI or CT scans. Treatment first focuses on rest, medications, and physical therapy. Surgery such as discectomy may be needed if conservative measures fail.
