The Chelsea loanee made another appearance off the bench in Everton's 1-1 draw with Arsenal.
Broja said: "I feel much better now. I'm happy I can come back on the pitch and play pain-free.
"That's all I wanted – to be pain-free, to enjoy my football, play in front of the fans and try to do the best for the team.”
He also said: "I'm 100 per cent sure, there's way more to come from me. There's still the best to come from me. There's so much more I can do.
"There's going to be moments where the goals are going to come, assists are going to come, and I'm going to play way better, for sure.
"But, like I said, the most important thing for me is to be back in and amongst it again, to play pain-free and to just leave whatever sort of injuries I've had in the past and just move on forward."
