The 33-year-old missed Stoke's final three matches of the Premier League season having been carried off in the 7-0 defeat at Chelsea on 25 April.
However, the Dane is optimistic he will be ready for his country's opening match in South Africa against Holland on 14 June.
"I've had a second scan and it's progressing really well," he said. Obviously, there is still a fair bit of bruising and muscle loss around the elbow, but it is healing really well and the capsule has sealed itself and the ligaments are intact which is hugely important for me.
"I am now starting to build it all up again and I had a first feel of the ball yesterday which was good, but again there is still a way to go. Hopefully, within a couple of weeks, with a lot of hard work in between, I will be back and close to resuming full training.
"The key is not pushing it too much because it is easy to do that when you feel good and you then run the risk of doing too much which in the end could backfire and put you in a worse situation than you were in originally," he said.
"I just have to keep ticking on slowly and be sensible, which I will be. There are still five weeks to go until the first game and at the moment I am very optimistic." Sorensen admitted he feared the worst when he sustained the injury but now, having had the elbow assessed, is in a much more positive frame of mind.
"I was devastated (when it happened) and I was crying as I was taken off the pitch because I thought that was it, I really thought my chances of going were gone," he told Stoke City Player. "Obviously though I am feeling a lot better now because it wasn't as bad as it could have been, and I suppose luck was on my side and the omens are looking good for me."
