Feeling achy or angry (4)
I believe the answer is:
sore
This clue is a double definition.
'feeling achy' is the first definition.
(I've seen this in another clue)
'angry' is the second definition.
(sore can mean angry or resentful)
(Other definitions for sore that I've seen before include "Spot of aggravation" , "Feeling pain or informally angry" , "Painful, or the source of pain" , "Raw place (on the body)" , "Wound; painful" .)
