The 34-year-old pulled out of Denmark's Euro 2012 qualifier with Cyprus on Tuesday night because of a muscle injury sustained in training last week.
He opted to play in Friday's 2-1 defeat to Portugal but had to be replaced.
However, Sorensen is optimistic of being ready for Saturday's trip to Bolton.
"It is a small tear in the hip area and an ultrasound scan showed there was some bleeding," he said.
"I'm walking all right, but it's the explosive work, like kicking and sprinting, which is a problem.
"The doctor in Denmark told me this injury usually lasts a week so there shouldn't be a problem for the weekend.
"It was a difficult decision to come home, but you cannot gamble on this sort of thing.
"I know I have made the right decision."
Stoke are looking for a third successive Premier League victory after losing their opening three games.
"We have turned a corner," Sorensen told The Sentinel.
"Our last win against Blackburn was a great team effort. With good results comes confidence and you can definitely see the change."
