I thought of using {-Daq}, but I didn't, since I remembered that
{-Daq} is to be used only for physical locations. On the other hand
"the ribs" are a physical location but since they are used
metaphorically, I decided eventually to go with {-vaD}.

But they denote a physical location within the metaphor.

{bIQ'a'Daq 'oHtaH 'etlh'e'} - the metaphorical sword is in the metaphorical ocean

{may'Daq jaHDI' SuvwI' juppu'Daj lonbe'} - when a warrior goes to either a physical or a metaphorical battle, he doesn't abandon his/her friends

The fact that you're speaking metaphorically about a thorn in ribs doesn't change the fact that you're speaking about a thorn located in ribs.
