Ben Campbell just wants to know what is wrong with his chest.
The Kiwi golfer has been plagued by a niggling injury since May where his chest swells up painfully, leaving him unable to play.
He boxed through the pain this month to earn his playing rights for this year's PGA Tour of Australasia, while he will tee it up in China this week as he looks to earn a tour card for the PGA Tour China series.
Campbell has had a range of tests but nobody can pinpoint what is causing the problem. He has also been struck by occasional fatigue.
"Everyone doesn't really have an idea at the moment of what to do or what's caused it," Campbell said.
