Pain bachelor hides (4)

I believe the answer is:

ache

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

'bachelor hides' is the wordplay.
'hides' indicates the answer is hidden within the clue.
'ACHE' is hidden within 'bachelor'.

(Other definitions for ache that I've seen before include "A dull lingering pain" , "Pine" , "painful" , "suffering" , "Longing" .)

I've seen this clue in The Sun.
