Tingling feeling chap in sand needlessly hides (4,3,7)
I believe the answer is:
pins and needles
'tingling feeling' is the definition.
(tingling sensation in limbs)
'chap in sand needlessly hides' is the wordplay.
'hides' indicates the answer is hidden within the clue.
'PINS AND NEEDLES' is hidden within 'chap in sand needlessly'.
(Other definitions for pins and needles that I've seen before include "Articles in haberdashery store" , "Prickly attack" , "that may lead to stitches?" , "complaint" , "Tingling" .)
