Lallana is focused on staying fit and helping his club in all competitions for the rest of the season.
He is also hoping that a sustained run in the team would put him back in Gareth Southgate's England plans for the World Cup in the summer.
"It tests different parts of you mentally but I feel that I have learned so much from being injured, different parts of the game," said the English midfielder.
"I have come back strong. I had a couple of little setbacks, a minor blister and then a tight muscle but that is what happens.
"Maybe it is credit to the manager over the last few games, holding me back. I had good training sessions but I am back now.
"I have lasted a game after being out for four, five months and I am in good shape."
Lallana went on to talk about Liverpool's progress in his absence, and how he is excited by what is to come in the rest of the season.
"We are in amongst the top four, in the last 16 of the Champions League," he added.
"There are so many great games to look forward to, like the FA Cup [at home to Everton on Friday].
"I'm absolutely delighted to be back and part of a winning team again.
"To concede as we did [in the 87th minute at Burnley] and then go up the other end and get our goal from a set-piece shows the steps we have made moving forward.
"It has been frustrating for me watching from the sidelines but it is great to see how much we have improved.
"To be a part of it again is a great feeling."
