Why Stretching Might Be Bad for Lower Back Pain, Sciatica, and Herniated Discs

Stretching when you experience muscle tightness in your lower back might be harmful for your sciatica, herniated disc, or chronic lower back pain. When it comes to managing back pain, not all exercises are created equal. Some movements can actually aggravate your condition rather than help it. This is an important concept that isn’t often discussed. As someone who has dedicated the last 20 years to understanding and reversing chronic lower back pain, I want to share some key insights.

Why Your Lower Back Muscles Tighten

When the spine is irritated or injured, your body has a natural protective mechanism—it tightens the muscles in your lower back. This stiffness is your body’s way of bracing the spine to prevent further damage. It’s like an alarm system: the pain tells you to stop harmful activity, and the muscle tension acts as a brace to protect the area from additional strain.

This response is part of your body’s inflammation process. The muscles tighten to restrict movement, creating a protective barrier around the spine. While it might feel instinctual to stretch those tight muscles for relief, this can actually backfire. Stretching works against the body’s natural protective response, undoing the muscular bracing that’s safeguarding the spine.

Why Stretching Can Make Things Worse

Yes, stretching may feel good temporarily because it increases blood flow and brings oxygen to the muscles. Muscles enjoy movement, and this momentary relief can lead you to believe the stretching must be helping. However, beneath the surface, you could be aggravating the very structure your body is trying to protect.

Stretching tight back muscles may create more irritation in the spine itself, causing it to respond with even greater tension. This cycle perpetuates imbalances, further misaligns joints, and can lead to chronic lower back pain that feels impossible to break free from.

Breaking Free from the Cycle of Stretching and Pain

Here’s how the cycle typically works:

1. The spine becomes irritated or injured, triggering pain and muscle tightness as a protective mechanism.
2. You stretch those tight muscles, temporarily relieving the tension but also undoing the body’s protective response.
3. This disruption irritates the spine further, causing more inflammation and muscle tension and reinforcing existing muscle imbalances.

Over time, this cycle can leave you feeling stuck, with pain and tightness that seem to return no matter what you do. Common exercises or even daily activities that involve bending, twisting, or high-impact motions can worsen the problem if your body isn’t properly aligned.

Stabilize Instead of Stretching

So, what should you do instead of stretching? The key is stabilization. By supporting your spine through the activation of surrounding muscles—those that aren’t already tensed as part of the protective mechanism—you can get some much-needed relief without undoing the body’s natural brace.

Your back muscles are doing their job to protect the spine, but they don’t need to carry the load alone. Activating the core muscles around your torso—the 270 degrees of support outside your lower back—can ease the burden on those tight back muscles. This allows the lower back muscles to feel safe to relax, naturally, when they feel the spine is stable and secure.

Gentle, Restorative Movements

Rather than stretching, focus on gentle, restorative movements that bring your body back into balance. Walking is a great example. It engages your entire body in a healthy, rhythmic motion that can help realign your joints over time.

Another effective approach is following the structured movement retraining program I’ve developed to address the root cause of the problem, muscle imbalances pulling the body into incongruent alignment. Core Balance Training focuses on intentional, progressive exercises designed to reconnect you to your core, restore joint congruency, and improve muscle coordination, so you can change the way you move and relate to your body, permanently.   

Stretching Has Its Place—But Timing Matters

Stretching isn’t inherently bad. It can be beneficial when tightness is coming in from a general lack of movement, like after a very long car ride. However, when tightness is part of the body’s inflammatory or protective response, especially in the lower back, stretching can disrupt your body’s natural defense mechanism and cause further irritation.

The key is to understand why your muscles are tight in the first place. If they’re responding to spinal irritation or an injury, stabilization and alignment should take precedence over stretching.

Building Long-Term Resilience

Overcoming chronic lower back pain isn’t about quick fixes. It’s about retraining your body, restoring balance, and progressively building strength and resilience. This gradual process allows your body to tolerate the demands of daily life and return to the activities you love—sports, hobbies, or more importantly, just going about your day without pain.

For now, take a moment to do something healthy for your body. Go for a walk, get down on the floor, and connect with your core. These small steps can lay the foundation for lasting relief and a stronger, more balanced body.

Until next time, remember: your body has the potential to heal when you give it the right support. Keep moving intentionally, and stay committed to your journey toward pain-free living.
