Play causing complaint? (3,5)
I believe the answer is:
hay fever
This clue is a double definition.
'play' is the first definition.
(I've seen this before)
'complaint?' is the second definition.
(medical complaint)
'causing' is the link.
(Other definitions for hay fever that I've seen before include "It results from an allergic reaction to pollen" , "Allergy with asthmatic symptoms caused by pollen or dust" , "Allergy - Noel Coward comedy" , "Pollinosis" , "Coward's" .)
