Well, going around bends is a problem (6)
I believe the answer is:
hassle
'problem' is the definition.
(I've seen this before)
'well going around bends' is the wordplay.
'well' becomes 'hale' (I've seen this in another clue).
'going around' means one lot of letters goes inside another.
'bends' becomes 'ss' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'hale' enclosing 'ss' is 'HASSLE'.
'is a' acts as a link.
Can you help me to learn more?
(Other definitions for hassle that I've seen before include "Annoying trouble" , "Bug" , "Struggle" , "Harass; pester" , "Lashes (anag)" .)
