Stomach woe
I believe the answer is:
ulcer
'stomach woe' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ulcer that I've seen before include "Cruel kind of bodily sore" , "Cruel form of stomach trouble?" , "Cruel sort of body sore" , "cause of suffering" , "Inflamed lesion" .)
