The 21-year old winger had made just 12 Scottish Premier League appearances because of groin and hamstring niggles but after netting from the penalty spot in the 5-0 win over Dundee United on the weekend is looking to become a more frequent figure in Neil Lennon's line-up.
"I am feeling good. I am doing a lot of running with the sports scientist and I just need to get more games," said Forrest.
"There has not been anything seriously wrong and maybe that's a good thing but it has been really frustrating, coming back and getting injured (again).
"Hopefully with a little bit of luck I can stay fit for the rest of the season."
