Former All Black and Otago stalwart Adam Thomson has spent at least a week in a Japanese hospital with medical specialists unable to determine the cause of his "excruciating pain".
The 35-year-old has been unable to walk due to the mystery illness and admits it will be a long road to recovery.
Thompson was admitted to the Tsukuba Memorial hospital in Tokyo with a yet-to-be diagnosed illness, causing the player nicknamed "BFG" and "Wooly Mammoth" due to his size "excruciating pain".
The flanker, who represented the All Blacks in 29 tests between 2008 and 2012, was hospitalised after being rushed to A&E in the middle of the night.
