Sickened (9)
(Other definitions for ailed that I've seen before include "Was unwell" , "was on the blink?" , "Was ill" , "Felt bad" , "was giving trouble" .)
'sickened' is the definition.

This is all the clue.
(Other definitions for nauseated that I've seen before include "Disgusted" , "Sickened" , "Revolted" .)
