A doctor aunt upset going round pound walking (8)
I believe the answer is:
ambulant
'walking' is the definition.
(thesaurus)
'a doctor aunt upset going round pound' is the wordplay.
'doctor' becomes 'mb' (Bachelor of Medicine, Medicinae Baccalaureus**).
'upset' indicates an anagram.
'going round' means one lot of letters goes inside another.
'pound' becomes 'l'.
'aunt' with letters rearranged gives 'uant'.
'uant' going around 'l' is 'ulant'.
'a'+'mb'+'ulant'='AMBULANT'
(Other definitions for ambulant that I've seen before include "Moving about, able to walk" , "Able to walk, not confined to bed" , "Of patient, able to walk" , "Walking, moving around" .)
