The Spanish playmaker has scored three goals in his last three games for the Gunners following trouble with an ankle injury.
"I'm doing well at the moment," Cazorla told the club's official website. "In the last few games I've been getting better physically and my confidence has been growing. I hope this continues from now until the end of the season.
"I had a bit of a bad time with my ankle problems and missed a few games but I hope to put that behind me and get back to my best in order to help the team to achieve as much as possible."
Arsenal are back in action on Friday night when they host Coventry City in the FA Cup fourth round.
