The 26-year-old has been assured he is in manager Andre Villas-Boas' plans, but says if there is not an opportunity to play regularly, he "will have to look elsewhere."
The 26-year-old came off the bench to help spark a Spurs comeback against Manchester City on Sunday, laying on the assist for Gareth Bale's goal in the 3-1 win.
However, with injuries hampering his season, Huddlestone has not started for the club since November, and feels if he does not feature regularly he may have to move on.
"There are times when I think I might need a move, especially if you don't play for a few months," Huddlestone told reporters. "I am 26. I missed a year to 18 months through injury. You just want to play every game, and if that opportunity is not at Tottenham then I will have to look elsewhere.
"It's been a frustrating few months. There was talk about [a move to] Fulham in January, although nothing was that close to happening where I thought it would be possible. I have been fully focused on getting us in to the top four and staying there. You speak to the manager every day and if you are not playing for a sustained period then you do wonder what's going on."
The midfielder went on to say that manager Andre Villas-Boas has assured him that he is in the plans with Spurs. Despite those reassurances, Huddlestone hasn't found much time on the pitch this season.
"The manager has reassured me that I am in his plans even though time-wise on the pitch it hasn't always been shown that way," he said. "You can't really judge it over the last five games or whatever. You've got to see the bigger picture throughout the whole season and speak to the manager and see if you're in his plans or not."
Huddlestone admits he feels slightly alienated at the club, but says he needs to give the situation time and take opportunities to prove himself.
"I don't feel back in the team properly," he added. "If you come on as sub you are brought on to make an impact and I feel in the last few games I have managed to do that.
"I guess it's just a case of biding your time and if you are given a slight opportunity towards the end of games try and prove to the manager that you should be in the starting side as well. The 4-3-3 we went to against City might give me more chances. It opens up another spot for a central midfielder, but it depends if the manager sees me as a deeper one because then that isolates the position."
