YEONGAM, SOUTH KOREA (AFP) - Kimi Raikkonen is to get treatment at the end of the season for a back complaint that has troubled him for more than a decade and nearly ruled him out of last month's Singapore Grand Prix.

The 33-year-old former world champion, who moves to Ferrari from Lotus for next year's campaign, said Friday that he wants to cure the recurring problem once and for all.

"It is not really surgery, but for sure we are probably going to do something," Raikkonen was quoted as saying by Autosport.com.

"I know what the issues are," the Finn added, saying that he would be fit to race at the Korean Grand Prix on Sunday.

He crashed into a wall on Friday in first practice but was back in his car for the afternoon session and said afterwards that his back was fine.

The back complaint is complicated and not entirely down to a crash he had in testing in 2001, Autosport reported.

"You cannot really say it is all (down to) that, but unfortunately with many years of driving and doing things it doesn't help," he said.

"I had some issues and small operations on it already and, when I was doing rallying, it is one of those things you have to live with.

"It is not ideal when you have issues on any part of your body. It has been there a long time and I am sure we can find some solution."

Raikkonen was only eighth-fastest in both practices.
