Injury Care

Low Back Pain

Low back pain can limit everything from training to daily life. We help identify what's driving it and build a plan to resolve it.

What's Causing Your Low Back Pain?

Low back pain is one of the most common reasons people seek care, and it can come from a range of sources — muscle strain, disc irritation, nerve involvement like sciatica, or mechanical issues related to posture, movement patterns, or training load.

For athletes and active adults, low back pain often develops gradually from repetitive movement patterns, insufficient core or hip strength, or a rapid increase in training volume. It can also be aggravated by prolonged sitting or poor movement mechanics during lifting or training.

Because the low back is connected to the hips, core, and overall movement mechanics, treating it effectively means looking beyond just the spine itself. At Modern Movement Clinic, we assess how you move as a whole system to understand what’s actually contributing to your pain, rather than treating the back in isolation.

Common Symptoms

Low back pain can present in different ways depending on the underlying cause. These are some of the most common patterns we see.

  • Dull, aching pain in the lower back
  • Pain that worsens with prolonged sitting or standing
  • Sharp pain with specific movements like bending or twisting
  • Radiating pain, numbness, or tingling into the leg (sciatica)
  • Muscle tightness or spasm in the low back
  • Pain that improves with movement but returns after rest
  • Stiffness, especially first thing in the morning

Common Causes

Low back pain typically develops from a combination of movement mechanics, strength or mobility limitations, and training or lifestyle factors. Identifying the specific combination behind your pain is what shapes an effective plan.

  • Muscle strain from lifting, training, or repetitive movement
  • Weakness in the core or hip muscles affecting spinal support
  • Disc irritation from repetitive bending or loading
  • Nerve irritation contributing to sciatica-type symptoms
  • Prolonged sitting or sedentary posture
  • Rapid increases in training volume or intensity

How We Evaluate It

Evaluation starts with understanding your pain patterns, training or activity history, and any related symptoms like radiating pain or numbness. From there, we assess movement throughout the spine, hips, and core to understand what’s contributing to the issue.

We pay close attention to how your back moves during activities relevant to you — whether that’s lifting, running, or simply daily movement — rather than assessing the spine in isolation. This gives us a clearer picture of whether the issue is coming from strength, mobility, movement mechanics, or a combination.

Chronic or recurring low back pain is rarely just a tissue problem. Long-standing pain often involves how stress, sleep, fear of movement, and past experiences with pain interact with what’s actually happening in the body. Living with pain that doesn’t resolve takes an emotional toll too, and that’s worth acknowledging as part of the plan — not brushed past. That’s why your evaluation includes a real conversation about what you’re dealing with — not just a physical exam. You’ll understand why it hurts, have a say in the plan, and leave with more than a generic protocol.

  • Core and hip strength screening
  • Activity-specific movement testing
  • Neurological screening when relevant (for radiating symptoms)

Common Questions

Is low back pain a sign of something serious?

Most low back pain is mechanical and related to strength, mobility, or movement patterns rather than something serious. That said, symptoms like radiating pain, numbness, or weakness are worth having evaluated to rule out nerve involvement.

Can I keep training or working out with low back pain?

In many cases, yes, with some modification. We’ll help you understand what’s safe to continue and what might need to be adjusted while we address the underlying issue.

What's the difference between low back pain and sciatica?

Low back pain generally refers to discomfort localized to the back itself, while sciatica involves radiating pain, numbness, or tingling that travels into the leg, usually from nerve irritation. The evaluation helps determine which pattern you’re dealing with.

Do I need imaging like an X-ray or MRI?

Not always. Many cases of low back pain can be evaluated and treated based on a thorough movement and strength assessment. Imaging may be recommended in specific cases, but it’s not typically the first step.

How long does low back pain usually take to resolve?

This depends on the cause, how long you’ve had symptoms, and how consistently you follow the plan. We’ll give you a realistic picture after your evaluation rather than a generic timeline.
