However, Mr Maistry later announced that the runner would stay overnight in hospital "for observation".
He declined to give specific details of Pistorius's medical complaint.
Pistorius, a double-amputee Olympic runner and multiple Paralympic champion, is serving a six-year jail term for murder after he shot his girlfriend, Reeva Steenkamp ,dead on Valentine's Day in 2013.
