I believe the answer is:

flesh wound

I'm a little stuck... Click here to teach me more about this clue!

'injury?' is the definition.
(flesh wound is a kind of injury)

'shelf causing superficial' is the wordplay.
'causing' indicates anagramming the letters.
'superficial' becomes 'wound' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'shelf' is an anagram of 'flesh'.
'flesh'+'wound'='FLESH-WOUND'
