Cause headaches for (3)

Ross

I believe the answer is:

try

'cause headaches for' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for try that I've seen before include "Hear court case" , "Gorse" , "Make an effort to get rugby score" , "Make an attempt" , "A rugby score crossing the line" .)

I've seen this clue in the Newsday.com and the Newsday.
