Not feeling very well after having had a local (4)
I believe the answer is:
numb
'not feeling' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for numb that I've seen before include "Deadened, desensitised" , "Feeling nothing" , "Lacking sensation" , "Deaden" , "Frozen" .)
