Pain in stomach eased (4)

I believe the answer is:

ache

'pain' is the definition.
(ache is a kind of pain)

'in stomach eased' is the wordplay.
'in' indicates a hidden word.
'ACHE' is hidden in the letters of 'stomach eased'.

(Other definitions for ache that I've seen before include "Long ? pain" , "Feel sore" , "burn" , "painful" , "yearning" .)

I've seen this clue in The Telegraph.
