The 31-year-old is confident of completing his rehabilitation in the coming weeks and returning to action on February 26 in Acapulco.
But Nadal, who has endured a series of punishing injuries throughout his career particularly in his knees, knows he cannot push himself forever.
“I am happy playing tennis. When the time comes to say goodbye, I’ll know,” Nadal said at a corporate event for Banco Sabadell.
“My life has more things than competing at the highest level.”
And Nadal reiterated that his body would stop him from playing as many tournaments as he used to in pursuit of certain goals, such as hanging onto the world No 1 spot.
“I’m not going to do crazy things to keep [the No 1 ranking], now my health is paramount,” Nadal added.
