The Finn came close to pulling out of the Singapore Grand Prix when he was struck down with back pain in practice.
The issue, which has struck him several times in his career, now looks set to require a permanent solution when the current run of flyaway races finishes.
"It is not really surgery, but for sure we are probably going to do something," said Raikkonen, who reported that his back was causing no problems in Korea. "I know what the issues are."
Raikkonen said the problems with his back were complicated, and were not all entirely down to a crash he had in testing for Sauber at Magny-Cours in 2001.
"You cannot really say it is all 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.
"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."
