The midfielder missed out on the trip to Newcastle last weekend because of the problem but has been back in training this week in preparation for the vital visit of City on Saturday.
"It was a throat infection again and I was disappointed to miss the game, but I am back now," revealed Teemu, who suffered with his tonsils during his time in France and is planning a removal during the close season.
"Definitely, after the last game of the season I will have them taken out and I will never have the problem again."
Despite our own setback against Newcastle, Teemu believes the season still holds a few plots to be unravelled for all clubs and insists focus must now be directed towards the next challenge, which is Manchester City at the Lane.
"Of course, if you lose, the most important thing is to bounce back and that is what we have to do on Saturday.
"Newcastle was always going to be tough, I saw the highlights and we also had some chances, but we lost and must do better against Manchester City.
"We have six games left now and every game is like a cup final really. We must take the three points next and concentrate on what we are doing and not results elsewhere.
"The main thing is to play well and win points."
Teemu Tainio reports that he should be back in contention for a place in the squad to take on Manchester City after recovering from a throat infection.
