The defender played the full 90 minutes, and is hopeful his injury misery is now over, and that he can help the team for the remainder of the campaign.
“I’m happy in terms of the nightmare being over,” he said. “When I first got injured I never envisaged being out for so long.
“It’s been a hard five months, so first and foremost it was about getting through the game and playing well.
“This is what you live for, it makes you feel as if you’re not helping everyone and you feel terrible. You need a mental toughness, you need to try and get through and fingers cross that’s me through it.”
McGinn was left frustrated on his return as the Spireites conceded within a minute and feels the team only have themselves to blame in the manner they gave the early goal away.
“We’re just shooting ourselves in the foot,” said McGinn.
“You’re struggling and confidence is low and you’re giving a team who are on a good bit of form – who have a boisterous crowd behind them - a head start, and it’s just criminal. It’s the reason why you’re down there in the table and not up there.”
The Spireites enjoyed plenty of possession during the game and did get a consolation goal through Sylvan Ebanks-Blake, but the Scot is looking for improvement in possession as well as without it.
“I was frustrated of the way we turned over the ball,” he said. “We had a lot of the ball but going into the final third, they nicked it and then they’re breaking on us.
“We had to play numerous passes to get into their final third, whereas I felt as if they nicked us and broke and we’re far too open.”
Chesterfield host Rochdale next Saturday at the Proact and the 26 year-old insisted the team still have belief going into the final seven games.
McGinn added: “While you’ve got the games you’ve got to believe or else you’re in the wrong job. Rochdale are a bigger threat away than I’d like to think they are coming to us, so hopefully we can get the three points.”
