Crossword Genius

Pain does father no good (4)

Ross

I believe the answer is:

pang

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

'father no good' is the wordplay.
'father' becomes 'pa' (pa can mean dad or father).
'no good' becomes 'ng' (abbreviation).
'pa'+'ng'='PANG'

'does' acts as a link.

(Other definitions for pang that I've seen before include "A sudden sharp feeling" , "Stab of pain" , "Sudden feeling of hunger or pain" , "Sudden sharp pain" , "Short violent pain" .)

I've seen this clue in the Evening Standard.
