Pain in each ear (4)

I believe the answer is:

ache

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

'in each ear' is the wordplay.
'in' indicates a hidden word.
'ACHE' is hidden in the letters of 'each ear'.

(Other definitions for ache that I've seen before include "Take an aspirin for it" , "Pine" , "Shakespearean character" , "Feel sore" , "Dull continuous pain" .)

I've seen this clue in the Evening Standard.
