Plus, that one looks fairly elderly (in choisya terms) so it's possible that minor damage in its early life has finally taken its toll, and the flow of sap up that main stem has been interrupted somehow. As above, cut it out (it aint gonna recover), and re-shape the shrub. Gives you some room for something else. Low geranium like G. 'Havana Blues' or 'Rozanne'.
