The 37-year-old had initially called an end to his playing career to take up a coaching role but returned in January to help his side knock rivals Manchester City out of the FA Cup.
Scholes suggested that carrying on his involvement with the club had made it even harder to take a back seat and that he found it difficult to get used to.
"The coaching was OK but it wasn't like playing," he told MUTV.
"I was still coming in every day and seeing players. It was difficult to adjust, I admit that. I really missed the playing side up until Christmas, when I went to see the manager."
Since the Oldham-born midfielder's return, the Red Devils have forged a five-point gap at the top of the Premier League and whilst the United man believes they are in a good position, he insisted the trophy is far from won yet.

He continued: "You would have snatched someone's hand off for this position a couple of months ago.
"We have put ourselves in a decent position but there is still a long way to go."
The Red Devils have the chance to extend their lead over Roberto Mancini's side on Sunday when they face QPR at Old Trafford. Although Scholes is wary of the threat City pose, he is confident that the title is in United's own hands.
He added: "We are going up against a very good team in City. They have had a fantastic season and they have a great squad of players that is capable of beating anybody.
"But with this five-point lead we just have to concentrate on ourselves."
