After returning from Olympic duty with Great Britain, the 23-year-old picked up an ankle injury in a pre-season fixture at Bristol City.
Cork returned in late September but limped off 81 minutes into his comeback match against Sheffield Wednesday in the Capital One Cup with a knee injury.
He has now overcome that setback and impressed on his first league game of the campaign, playing the full 90 minutes on Saturday in the draw with Swansea City.
"I feel really good," Cork said. "I thought I was only going to get an hour or 70 minutes, but I felt really good.
"The manager asked me at half-time how I felt and again about the hour mark and I said I felt fine. I stayed on and felt good.
"I am happy with how I played, it was just disappointing because we played really well and the lads have done great.
"It is just so unfortunate with the position we're in we haven't got the three points because we desperately need them at the minute.
"But if we keep playing like that and we keep playing the way we are, I am sure it will come along eventually.
"It is always hard when you think you're going to win and that happens.
"We know we did reasonably well and we've got a massive game against QPR so hopefully we can go there and take some points."
