Flipping painful love for Oedipus (4)

I believe the answer is:

eros

I'm a little stuck... Click here to teach me more about this clue!

'love for oedipus' is the definition.
'eros' can be an answer for 'love' (Greek god of love). I'm not sure about the 'for oedipus' bit.

'flipping painful' is the wordplay.
'flipping' says the letters should be written in reverse.
'painful' becomes 'sore' (similar in meaning).
'sore' written backwards gives 'EROS'.

Can you help me to learn more?

(Other definitions for eros that I've seen before include "Cupid, son of Aphrodite" , "London landmark" , "Winged archer" , "Piccadilly 14 ac statue" , "Asteroid - Greek god of love" .)
