A hairline fracture causes a dull or sharp pain, especially during activity.
The affected area may swell and feel tender to the touch.
Pain often worsens when using the injured bone, like walking on a fractured foot.
Some hairline fractures cause bruising, though it’s not always visible.
The pain is often specific to one spot where the bone is cracked.
The pain may subside or decrease when resting the affected area.
Even after rest, some level of discomfort or soreness may linger.
The fractured area might feel weak or unstable during movement.
You may notice difficulty or stiffness when trying to move the affected part.
Unlike full fractures, hairline fractures typically don’t cause visible bone displacement.
