Hi,
Can you be more specific about the positive palpation results? Exactly where on the fibula - ant-post-lat/neck/head/shaft etc.
Also what does the person do that aggs the condition other than clockwise palpation? Does the condition appear to have pattern e.g. inflammatory/degenerative/non mechanical? How old is this person?
Have you checked in depth for neurodynamic or muscular provocation with particular biasing for popliteus pain (end range knee ext + ER).
To assist more info particularly subjective reports will be very helpful.
Cheers
