Kei Nishikori says he has been having breathing problems, affecting his performance on court.
The No. 5 fell to fellow Japanese Yoshihito Nishioka in the second round at Cincinnati, his third straight defeat.
"I've been having trouble breathing since Wimbledon, so I've got to get it checked," he said.
