Can pain tell us whether a bone has healed?🦴
Pain is important in the assessment and management of a bone stress injury.
But it is not a direct measure of:
• How much structural damage is present
• Whether a fracture line has developed
• How quickly the injury is healing
• Whether the athlete is ready to run
Bone is innervated, but that innervation is not distributed uniformly.
Sensory nerve fibres are most abundant in the periosteum, followed by the bone marrow, with substantially fewer found within mineralised cortical bone.
This means the pain experience may depend partly on which tissues are involved, rather than simply reflecting the extent of structural damage.
Two athletes with different injuries may therefore report similar pain.
Two athletes with apparently similar injuries may report very different pain.
Pain can also change as local inflammation, mechanical distortion, load exposure, expectations and broader contextual factors change, without necessarily indicating an equivalent change in bone integrity.
This does not make pain irrelevant.
Pain and focal tenderness remain important clinical signals and should help guide loading progression. But they should be interpreted alongside:
🔸 Injury location and associated fracture risk
🔸 Cortical versus trabecular involvement
🔸 Presence or absence of a fracture line
🔸 Imaging findings when clinically indicated
🔸 Walking and functional loading tolerance
🔸 Recent training exposure
🔸 Nutritional, hormonal and skeletal health factors
The takeaway: Pain can help guide management.
Pain alone cannot grade a bone stress injury, confirm healing or clear an athlete to return to running.
