Hi and thanks for the query,
its of utmost importance to determine whether this pain is of mechanical or inflammatory origin , for this shall shape the management. An X ray
of the ankle is an appropriate exam to be done. Markers of inflammation like ESR
and blood count parameters could tell us if there is an active inflammatory process going on or not.
Visiting your orthopedic surgeon for a proper evaluation and specific care is my advice.
Thanks and best regards,
