Feeling sore (4)
I believe the answer is:
achy
'feeling sore' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for achy that I've seen before include "suffering dull pain" , "Needing aspirin?" , "Feeling in need of an aspirin?" , "Dully painful" , "Giving pain" .)
