Spanish tennis superstar Rafael Nadal has revealed that he is still in pain despite his incredible form since returning from injury and denied suggestions that a hi-tech treatment was the reason of his amazing comeback.
According to Sport24, a British newspaper recently argued that the use of hi-tech training machinery and platelet-rich plasma therapy (PRP) were key reasons for the Spaniard's revival.
However, the 27-year old said at the Shanghai Masters that while a combination of machines and PRP had 'worked unbelievable' on his knee in the past, there was no magic cure this time around.
PRP, known as 'blood-spinning', involves taking an athlete's blood and spinning it in a centrifuge to increase the platelet count and it is then re-injected in the affected area, the report said.
The practice is not banned and was removed from the World Anti-Doping Agency's prohibited list for 2011, the report added.
Nadal said his team was working constantly to find solutions to manage his knee, which he admitted was not 100 percent perfect, the report further said.
Nadal, however, said that the felling on the knee is very good for him because even if he has pain on a lot of days, it does not limit his movements, adding that it was the most important thing because he was free while playing.
The Mallorcan, whose US Open victory last month gave him 13 Grand Slam wins, just four behind Roger Federer, said it was special to be world number one again, a chance he did not believe he would have.
In Shanghai, he can become the first man to win six Masters titles in one year, an achievement, which would add further gloss to his remarkable season, according to the report.
