Suffered pain in the neck (4)
I believe the answer is:
bore
This clue is a double definition.
'suffered' is the first definition.
(I've seen this before)
'pain in the neck' is the second definition.
(both can mean an annoying person)
(Other definitions for bore that I've seen before include "River wave; drill" , "Tedious person; steep wave" , "Held" , "Drill or be tedious" , "Tidal wave; drill" .)
