A cervical disc bulge is when a disc between the vertebrae in your neck spreads beyond its normal border, most often at C5-C6 or C6-C7. Bulges are very common on MRI, often without pain, and when they do cause symptoms most people recover without surgery.

| Most common levels | C5-C6 and C6-C7 |
|---|---|
| Key symptoms | Neck pain and stiffness, pain or tingling into the shoulder blade, arm or hand |
| Main treatment | Pain relief, neck and upper back strengthening, nerve glides, desk habits |
| Typical improvement | 6 to 12 weeks; arm symptoms can take a few months |
| Surgery | Rarely needed; mainly for spinal cord signs or progressive weakness |
What causes it?
Discs naturally lose water and height with age, making the outer layer more prone to bulging. Long hours at a desk or on a phone, heavy lifting, previous neck injury such as whiplash, and smoking can all add to the load. A bulge differs from a herniation, where the inner disc material pushes through the outer layer.
Symptoms
- Neck pain and stiffness, often worse after sitting at a screen
- Pain between the shoulder blades or across the top of the shoulder
- Pain, pins and needles or numbness down the arm into specific fingers (cervical radiculopathy)
- Headaches starting at the base of the skull
The fingers affected give a clue to the level: C6 often affects the thumb and index finger, C7 the middle finger.
Seek urgent medical care if: you notice clumsy hands, difficulty with balance or walking, worsening weakness in the arms or legs, or bladder changes. These can be signs of pressure on the spinal cord (myelopathy).
How is it diagnosed?
A physiotherapist examines neck movement, nerve function, strength and reflexes. An MRI is helpful if symptoms are severe, not improving after several weeks, or if there are spinal cord signs.
Treatment
- Pain relief: hands-on treatment, positions that ease arm pain, heat and sleep advice
- Deep neck flexor training: chin tucks and gentle isometric holds
- Upper back and shoulder blade strengthening to support posture
- Nerve glides when there are arm symptoms
- Gradual return to gym, sport and work
What you can do at home
- Take a short movement break every 30 to 45 minutes at your desk
- Raise your screen to eye level and keep your phone up rather than looking down
- Sleep on your back or side with a pillow that keeps your neck level
- Keep moving gently; avoid a neck collar unless your doctor advises one
Outlook
Most people see a clear improvement within 6 to 12 weeks. Disc bulges and herniations can shrink naturally over time, and building strength reduces the chance of it returning.
Frequently asked questions
Can a cervical disc bulge heal on its own?
Yes. Many settle with time, and a targeted exercise programme speeds recovery.
Should I stop going to the gym?
Usually not. We adjust exercises that load the neck heavily, such as overhead pressing, while you rebuild strength.
What is the best sleeping position?
On your back or side with a supportive pillow. Avoid sleeping on your stomach with your head turned.
When is surgery considered?
For spinal cord compression signs, progressive weakness or severe arm pain that does not improve with good conservative care.
