-Gradual onset of pain following instability or acute ankle sprain 

-Pain on anterolateral aspect of ankle.

-Instability sensation on foot inversion and eversion.

-End range pain with passive inversion and eversion. 

-Often severe pain in morning which improves on warming up 

-HOPC: injury mechanism (plantar flexion with supination/inversion) 

-PMH: Previous ankle injury, ankle instability.

-Aggr: Running on unstable surfaces 

TESTS:

-Lower limb alignment: Standing posture (eg.high arch vs low arch).
