Temer in recent days has forgone some of his official duties to recover in an official presidential residence after treatment for a urinary tract infection.
Responding to questions from journalists during a brief morning walk, Temer said his health was "perfect, extremely recovered, thanks to God."
Still, he will need to travel to Sao Paulo, Brazil's largest city, for another series of tests later this week, Temer said.
In October, Temer, an unpopular leader who is attempting to push through a series of reforms before the October 2018 elections, underwent treatment for an aortic obstruction and prostate enlargement.
In recent weeks, he has suffered from urinary tract issues amid complications after a December surgery.
He has canceled a number of official events scheduled for January. The next trip that remains on his agenda is the World Economic Forum in Switzerland towards the end of the month.
