Treated a sprain
I believe the answer is:
iced
'treated a sprain' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for iced that I've seen before include "Covered with flavoured sugar topping" , "Dressed in a sweet coat" , "Frosted over" , "Decorated (a cake)" , "Made very cold" .)
