Doctor seeing I'd come around (6)
I believe the answer is:
medico
'doctor' is the definition.
('medico' can be a synonym of 'doctor')
'i'd come around' is the wordplay.
'around' indicates an anagram.
'id'+'come'='idcome'
'idcome' anagrammed gives 'MEDICO'.
'seeing' is the link.
(Other definitions for medico that I've seen before include "Doctor" , "Health practitioner" , "quack" .)
