The Wales international was sidelined with a long-standing, heredity back problem and has admitted he considered a career away from football.
But Edwards, who could feature for his country in Tuesday's Euro 2012 qualifier against Bulgaria, made his comeback in a goalscoring performance against Millwall in the Carling Cup in September.
And now the 25-year-old is able to reflect on his time on the sidelines, when he was scared he would not play another game.
"Once I was injured, I had doubts over whether I would ever get back," Edwards told the Sunday Mercury. "When I first felt the pain, I thought I'd be out for only a week and back playing.
"I had targets. First it was six weeks, then it was pushed back to three months, then four and six months. That was the hardest part of the injury.
"There were two or three times where I was close to training. Then in my first training session back I felt it go again. There was a real sore pain.
"Then I thought, 'is this really going to get any better?' and, 'is this something I'm going to have to live with and prematurely finish my career?'.
"The physios at Wolves were brilliant and they were always confident that it wouldn't happen. But when you are the one who is told you are out then you fear the worst."
Edwards also believes his injury hell will make him a better player in the future because he can deal with the low points.
"It has made me stronger in the long-term even though I have been in a dark place for the last six months," he said.
"I've always thought 'what would you do if you weren't playing football?'
"I've done A-Levels and always thought about things I'd like to be involved in, but at the same time I never felt ready to think about it properly.
"The injury hit home how much I've relied on football and made me think a little bit more about being ready for when it does end. It's helped in that way."
