David Blaine has been in "horrific" pain for the last week, describing his seven days in a sphere of water as the worst pain he has ever experienced.
With only hours to go before David Blaine's televised grand finale, the illusionist - known for his brand of high profile, high publicity stunts - said he is experiencing terrible pain and is becoming concerned about his health.
"I think the time has started to really take its toll on my body. It has started to become horrific in many, many ways.
"Every muscle doesn't just ache, it feels like a sharp shooting pain, like a knife being stabbed."
Blaine's skin, which has become shrivlled and pruned due to the water, hurts as well, and he is worried about his muscles - which have begun to atrophy.
"I don't think it's permanent, but I've never felt this kind of pain in a stunt before."
Blaine will attempt to hold his breath for a world record breaking nine minutes, at 8.30 Monday night New York time after spending over 170 hours submerged in the sphere, while escaping from handcuffs and around 70 kilograms of chains.
