Treatment for swelling in reserve team? (7)
I believe the answer is:
icepack
'reserve team?' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'treatment for swelling in' is the wordplay.
'treatment' becomes 'pack' (pack is a kind of treatment).
'for' is a charade indicator (letters next to each other) (I've seen this in other clues).
'swelling in' becomes 'ice' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'pack' after 'ice' is 'ICEPACK'.
Can you help me to learn more?
(Other definitions for icepack that I've seen before include "something from physio's bag?" , "potential spine-chiller" .)
