Maybe Henry's hip is troubled with cyst (9)
I believe the answer is:
physicist
'maybe henry's' is the definition.
I can't tell whether this definition defines the answer.
'hip is troubled with cyst' is the wordplay.
'troubled with' is an anagram indicator.
'hip'+'is'='hipis'
'hipis' mixed up with 'cyst' can make 'PHYSICIST'.
Can you help me to learn more?
(Other definitions for physicist that I've seen before include "One studying the nature of matter" , "To become a scientist, doctor gets a name change to the street" , "Expert in the science of matter and energy" .)
