Rachel comes out of cartwheeling with sharp, sudden pain (6)
I believe the answer is:
twinge
'sharp sudden pain' is the definition.
(I've seen this in another clue)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for twinge that I've seen before include "Sharp pain (of conscience?)" , "Small pain eg from conscience" , "Slight pain (of conscience?)" , "Sudden localised pain" , "Sudden stinging pain" .)
