Relieved after cold came to an end (6)
I believe the answer is:
ceased
'came to an end' is the definition.
('cease' can be a synonym of 'come to an end')
'relieved after cold' is the wordplay.
'relieved' becomes 'eased' ('ease' can be a synonym of 'relieve').
'after' is a charade indicator (letters next to each other).
'cold' becomes 'c' (eg on taps).
'eased' put after 'c' is 'CEASED'.
(Other definitions for ceased that I've seen before include "Stopped, quitted" , "Concluded" , "Stopped, ended" , "Stopped, quit" , "Came to an end" .)
