Tinder users, say, receiving husband's complaint (8)
I believe the answer is:
shingles
'complaint' is the definition.
(shingles is a kind of disease)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for shingles that I've seen before include "Infection" , "Wooden tiles and painful condition" , "Herpes zoster" , "Viral inflamation, with rash of painful blisters" , "Roof tiles or painful ailment" .)
