Male concealing answer is in discomfort (7)
I believe the answer is:
malaise
'discomfort' is the definition.
(I know that malaise is a type of discomfort)
'male concealing answer is' is the wordplay.
'concealing' is an insertion indicator (back).
'answer' becomes 'a' (abbreviation eg in Q and A).
'a'+'is'='ais'
'male' enclosing 'ais' is 'MALAISE'.
'in' acts as a link.
(Other definitions for malaise that I've seen before include "flu perhaps" , "Feeling of impending illness" , "General feeling of unease or illness" , "Uneasy feeling" , "Feeling of illness or mental uneasiness" .)
