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

'complaint' is the definition.
The answer and definition can be both states of affairs as well as being singular nouns.
Maybe you can see an association between them that I don't see?

'claret-covered minor celeb' is the wordplay.
'claret-covered' becomes 'blood' (I can't justify this - if you can you should believe this answer much more).
'minor celeb' becomes 'blister' (a B-lister is a celeb less famous than an A-lister).
'blood'+'blister'='BLOOD BLISTER'

'makes' is the link.

Can you help me to learn more?

(Another definition for blood blister that I've seen is " Result of a bruise or other injury - to lob bridles (anag)".)
