What Is Cervical PIVD?
Cervical PIVD (Prolapsed Intervertebral Disc) occurs when the soft inner core of a neck disc pushes through its outer layer and presses on nearby nerves — essentially a slipped or herniated disc in the cervical spine.
It frequently develops at the C5-C6 and C6-C7 levels, the two segments handling the most movement and load in the neck, making them especially prone to wear and herniation.
Why C5-C6 and C6-C7 Are Common Sites
- C5-C6: Often causes pain, numbness, or weakness in the thumb and forearm, along with biceps and wrist weakness
- C6-C7: Typically triggers symptoms in the middle finger and back of the forearm, with triceps weakness
- Both levels sit at the most mobile part of the cervical spine, making them the most frequent sites for disc herniation

Common Symptoms
Neck pain that may radiate into the shoulder and arm
Tingling or numbness following a specific pattern down the arm into the fingers
Muscle weakness in the arm, wrist, or hand depending on the affected level
Pain that worsens with certain neck movements, such as looking up or turning
Reduced grip strength or difficulty with fine hand movements
What Causes It?
- Age-related disc degeneration reducing cushioning ability
- Poor posture and prolonged forward head position from screen use
- Sudden neck injury, such as whiplash from an accident
- Repetitive strain from certain occupations or activities
- Genetic factors affecting disc strength and structure
How It's Diagnosed
A physical exam checking reflexes, muscle strength, and sensation in a specific pattern identifies which nerve root is affected.
An MRI scan is the most reliable way to confirm the exact location and severity of the herniation, while a CT scan may assess bone structure when needed.
Treatment Options
Most cases of cervical PIVD improve with non-surgical treatment, especially when diagnosed early.
- Physiotherapy to relieve nerve pressure and improve neck mobility
- Cervical traction to reduce pressure on the affected disc and nerve
- Posture correction and ergonomic adjustments
- Pain-relief or anti-inflammatory medication, as advised by a doctor
- Epidural or targeted injections for persistent nerve pain
- Surgery, considered only for severe, unresponsive cases or significant weakness
When to See a Spine Specialist
- Arm pain, numbness, or weakness that doesn't improve after a few weeks
- Progressive weakness in the hand or arm
- Neck pain following an injury or accident
Since symptoms often point precisely to the affected disc level, an early diagnosis makes it much easier to relieve nerve pressure and restore normal arm and neck function.
