Made worse (10)
I believe the answer is:
aggravated
'made worse' is the definition.
('aggravate' can be a synonym of 'make worse')
This is all the clue.
(Other definitions for aggravated that I've seen before include "Made worse" , "Worsened" , "Made (offence) more serious (legal)" , "Annoyed" , "made more severe" .)
