Pinches a couple around aged centre (7)
I believe the answer is:
twinges
'pinches' is the definition.
(I know this)
'a couple around aged centre' is the wordplay.
'a couple' becomes 'twin'.
'around' says the letters should be written in reverse.
'aged centre' becomes 'seg' (I can't explain this - if you can you should give a lot more credence to this answer).
'seg' in reverse letter order is 'ges'.
'twin'+'ges'='TWINGES'
Can you help me to learn more?
(Other definitions for twinges that I've seen before include "having some discomfort" , "Small or mild darts of pain" , "Small stabs of pain" , "Sharp stabs of pain" , "Sudden pains" .)
