Left-winger's short-lived pain (6)
I believe the answer is:
twinge
'pain' is the definition.
(I know that twinge is a type of pain)
'left-winger's short-lived' is the wordplay.
'TWINGE' is hidden in amongst the letters.
But, I am unsure how this is indicated.
Can you help me to learn more?
(Other definitions for twinge that I've seen before include "Momentary pain" , "A slight jab of pain (6)" , "Sudden localised pain" , "Brief sharp pain" , "A small pang, of pain or concience" .)
