Is Your Running Pain a Bone Stress Injury? Here’s What to Watch For - By Blueprint Physio and Performance – Expert Physio for Runners in Marrickville

Not all running pain is created equal. If you’re feeling a niggle that just won’t go away—especially deep in your shin, foot, or hip—it could be a bone stress injury (BSI) rather than just tight muscles or joint stiffness.

Left untreated, these injuries can progress into stress fractures, keeping you off the track for weeks or even months. At Blueprint Physio and Performance, we help runners across Marrickville and Sydney’s Inner West catch these injuries early and return stronger.

🦴 What Is a Bone Stress Injury (BSI)?

A bone stress injury occurs when your bones are overloaded with repetitive stress without enough time or fuel to recover. Unlike acute injuries (like ankle sprains), BSIs develop gradually—and often go unnoticed until the pain becomes persistent.

They fall along a spectrum:

• Stress reaction – early signs of bone overload

• Stress fracture – a small crack in the bone

🚨 How to Tell If You’re Developing a BSI

1. Location of Pain

BSI pain is typically:

• Deep, sharp, and localised to one specific spot

• Felt in weight-bearing bones like:

  • Shins (tibia)

  • Feet (metatarsals, navicular)

  • Hips or pelvis

  • Occasionally the heel (calcaneus)
    

It’s usually not diffuse, like muscle tightness.

2. Pattern of Pain

• Begins as mild discomfort during or after running

• Progresses to pain earlier in your run, eventually showing up during daily activities

• Doesn’t improve with stretching or foam rolling

• Can linger overnight or be tender when pressing directly on the bone

3. Signs of Low Energy Availability (LEA) or Underfueling

If your body doesn’t get enough energy, it can’t repair the tiny micro-damage bones endure from training. Watch for:

• Skipping meals or chronically dieting

• Low-carb or dairy-free diets without medical guidance

• Fatigue, irritability, or poor recovery

• Missed periods (in women), or low libido/low testosterone in men

LEA is common in recreational and competitive runners—not just elites.

4. Sudden Spike in Training Load

Overtraining is one of the biggest contributors to BSIs. Red flags include:

• Increasing mileage too quickly (more than ~10% per week)

• Adding intense speed work or hill sessions without proper base

• Not building in rest days or deload weeks

• Running through fatigue or existing niggles
  

Also consider other risk factors: poor footwear, hard surfaces, and biomechanical imbalances (e.g. overpronation or poor hip control).

🧠 BSI vs Other Running Injuries

Injury	Pain Type	Location	Pattern
BSI	Sharp, local	Bone (e.g. shin, foot)	Worsens with loading, becomes constant
Muscle strain	Achy/sore	Muscle belly	Eases with movement
Tendon pain	Stiff in morning, eases with warm-up	Near joints (e.g. Achilles)	Often improves with activity
Plantar fasciitis	Sharp in heel	Arch or heel	Worst in morning

Knowing the difference helps you respond early—and appropriately.

🏃‍♂️ Runners, Don’t Push Through the Pain

Pain that doesn’t settle within a few runs, or that’s getting worse, is worth investigating. BSIs are best caught early—when rest, load management, and targeted strength can fix the issue without long-term downtime.

At Blueprint Physio and Performance, we assess:

• Running technique & gait

• Muscle imbalances or overuse patterns

• Nutrition and training load history
  

We’ll help you recover and prevent recurrence—so you can train smarter, not harder.

✅ TL;DR – Bone Stress Injury Red Flags

• Localised, sharp bone pain

• Worsens with load, improves with rest—then returns faster

• Underfueling or restrictive eating habits

• Sudden spike in training volume/intensity

• Doesn’t respond to massage, stretching, or rest alone

Don’t wait until it becomes a fracture. Early physio = faster return to running.
