If your lower back has suddenly “locked up” and you’re struggling to move, it can feel painful, limiting, and scary. One of the most common causes of this presentation is irritation of a spinal disc.
This guide will help you:
- Recognise if your symptoms may be disc-related
- Understand what’s happening in your body
- Know what to avoid
- Take the first steps to get moving again safely
What’s Happening in Your Body
When a disc becomes injured, your body shifts into a protective strategy.
Instead of allowing smooth, coordinated movement, your system becomes:
- Overprotective (over-guarding)
- Under-responsive in awareness (under-sensing)
This is helpful in the short term—it’s your body trying to protect an injured area.
But if it continues, it creates problems:
- Movement becomes difficult and stiff
- You may feel “stuck” and unsure how to move
- Your ability to sense position (proprioception) reduces
- The risk of further strain or recurring flare-ups increases
To recover properly, we need to gently transition out of this protective state and reintroduce safe, controlled movement.
Movement helps:
- Improve circulation and nutrient delivery
- Assist in clearing inflammation
- Restore proprioception (your body’s awareness of position)
Signs It May Be a Disc Issue
Some common indicators include:
- Pain when bending forward (flexion)
- Difficulty or pain with prolonged sitting
- Pain when coughing or twisting
- Referred pain down the leg (sometimes more noticeable than the back pain itself)
- A deep, achy pain in the lower back rather than superficial soreness
- Feeling “locked into a posture” or unable to stand up normally
What to Avoid (Early Stage)
In the initial phase, it’s important to avoid movements that aggravate the disc:
- Heavy lifting
- Prolonged sitting
- Repeated or sustained forward bending
- Slouched postures that load the spine
Sitting in particular can be problematic, as it often places the spine into flexion and increases pressure on the discs.
What to Do: Gentle Movement to Get Things Going
The goal is not to push through pain, but to reintroduce safe, gentle movement.
1. Walking (Start Here)
- Short, frequent walks on flat ground
- Encourages natural, rhythmic movement
- Helps reduce guarding, improve circulation, and restore body awareness
2. Gentle Mobility Exercises
On all fours (Cat–Cow):
- Slowly move between arching and rounding your back
- Keep movements controlled and within comfort
On your back (Knee rocking):
- Lie on your back with knees bent
- Gently rock knees side to side
- Or slowly flex and extend the spine
These movements help loosen the system and restore confidence in movement.
3. Extension-Based Movements (If Appropriate)
If your symptoms are consistent with a disc bulge that is aggravated by flexion, extension movements can be helpful.
Examples:
- Cobra position (McKenzie-style extension)
- Standing back extensions (hands on hips, gently arch backwards)
These can help reduce disc pressure in certain cases and may even help slow or reverse the progression of an emerging disc bulge.
Putting It All Together
When your back locks up due to a disc issue, your body is trying to protect you—but it can get stuck in that protective mode.
Your role in recovery is to:
- Avoid aggravating movements
- Reintroduce gentle, controlled movement
- Gradually restore your body’s ability to sense and move properly
This is how you move from being “stuck” to moving freely again.
Watch the Exercises in Action
To make this easier to follow, I’ve put together a short video demonstrating these movements step by step above…
If you’re unsure whether your symptoms fit this pattern—or if things aren’t improving—it’s important to get assessed.
