Carragher believes his midseason injury break has freshened him up.
"You have to look at the positives of an injury in that it gives you a rest and takes you out of the firing line," Carragher said.
"Maybe you can look back and say 'It's done me good' - but I'd much rather be playing because I love being in the firing line. You don't want to be out but sometimes you try to put a silver lining on it and try to kid yourself in your own head because you are devastated when you get injured.
"Any injury comes at a bad time but there were a lot of games when I was injured because it was over Christmas. But it has happened now. I have been very lucky with injuries throughout my career and hopefully there won't be too many more.
"Maybe the rest will prove between now and the end of the season that it has helped me."
