Sunderland striker Fraizer Campbell has said there are no lingering doubts about the injuries that have stalled his career in the last 16 months.
The 24-year-old has been on the sidelines following a troublesome knee injury, but made a scoring return at home to Middlesbrough on Sunday.
"You can't let that creep into your mind or it'll affect your performance," Campbell told BBC Newcastle.
"I didn't have the fear before I did it, so I've got to get back to that."
Since joining the Wearsiders from Manchester United, the Huddersfield-born forward has had a tough time with injuries, with the initial cruciate ligament injury occurring against Manchester City in August 2010.
He then suffered a further set-back in April last year, when he was forced to undergo a second operation following a recurrence of the problem.
With the surgery a success, Campbell's return to action has been carefully managed.
Initially the England Under-21 international was given a handful of reserve team matches and behind-closed-doors friendlies to regain match fitness before joining up with the first team.
"You feel like you're ready to go, but we've got a great medical staff and a great coaching staff here," he added.
"They don't want to rush me back, especially with the team doing so well.
"It's frustrating for me, but I know everybody's looking out for me.
"I knew I loved football before but being out for so long makes you really appreciate what you've been missing."
