Rafael Nadal said he spent most of his tennis career in pain due to a degenerative foot condition in a new Netflix documentary.

The revelation provides a rare look at the physical toll endured by one of the sport's most successful athletes to maintain a world-class level of competition.

Nadal, who has won 22 Grand Slam titles [1], described a grueling battle with a career-threatening injury that lasted almost two decades [2]. In the documentary, he said he used extreme measures to stay on the court, including a surgical procedure designed to numb his foot to mask the chronic pain [2].

Beyond the surgical intervention, the 22-time champion [1] revealed the systemic impact of his pain management. He said that the heavy use of anti-inflammatory medications, necessary to manage the condition, eventually caused damage to his intestines [2].

"I spent most of my career in pain because of a degenerative condition," Nadal said [1].

The documentary highlights the contrast between his public dominance and the private struggle to manage a condition that threatened to end his career prematurely. Nadal said he required mental and physical endurance to compete while dealing with a constant source of physical distress.

"I have lived with this foot pain for almost two decades," Nadal said [2].

"I spent most of my career in pain because of a degenerative condition."

Nadal's disclosure underscores the hidden physical costs of elite professional sports. By detailing the use of nerve-numbing surgery and the subsequent internal organ damage caused by medication, the account illustrates how modern athletes may push beyond biological limits through aggressive medical intervention to prolong their careers.
