Rafael Nadal, winner of a record 22 Grand Slam titles, has spoken candidly about the relentless physical toll that underpinned one of tennis's most extraordinary careers, revealing that he lived in constant fear of each season being his last as he managed a debilitating chronic foot condition. The retired Spanish champion made the disclosures in an interview with the BBC, timed to coincide with the release of the Netflix documentary series 'Rafa', which examines the physical and psychological demands of his professional life.

A Diagnosis That Could Have Ended Everything

Nadal received his first diagnosis of the rare Müller-Weiss syndrome — a degenerative bone disorder of the foot — just two months before winning his debut French Open title at the age of 19. During the 2005 Madrid Open final, he sustained a broken bone linked to the condition, a consequence partly attributed to the gruelling physical training regime overseen by his uncle, Toni Nadal, during his formative years.

Rather than accepting the diagnosis as a career death sentence, Nadal went on to claim a staggering 13 additional Grand Slams across nine years, winning at least one major title every season and cementing his status as the greatest clay-court player the sport has seen.

The Mental Weight Behind the Trophies

'Tennis became a race against time,' Nadal told the BBC. 'Always doubting my head about how long I can last with this foot? I never knew how long my career would last.' He added: 'I always thought, maybe it's the last year, so there's no time to stop.'

The public image of relentless triumph, he acknowledged, masked a private landscape of continuous uncertainty. Every title was shadowed by the question of whether his body would hold for another campaign.

Pain Management and Its Consequences

Sustaining a career at the sport's highest level also produced two serious secondary health complications: a recurring tendinitis in his left knee and intestinal perforations caused by the prolonged, excessive use of painkillers. During certain matches, Nadal had no option but to receive anaesthetic injections simply to take the court.

Most strikingly, his 2022 French Open victory — his 14th Roland Garros title and the final Grand Slam of his career — was achieved while playing with a leg in which he reportedly had almost no feeling. The win was, in retrospect, both his crowning achievement and a measure of how far he had pushed the limits of what the body can endure.

What Kept Him Going

Reflecting on the choices he made, Nadal was unapologetic. 'I've had to make decisions about my health, where you are on the borderline between right or wrong,' he said. 'But if I hadn't explored all that, I probably would have had 10 fewer Grand Slams... This is the reality.'

He identified passion as the decisive factor: 'The key was that the suffering was less than my passion and my happiness for what I was doing.' The 39-year-old, who was part of the sport's celebrated 'Big Three' alongside Roger Federer and Novak Djokovic, has since retired from professional tennis. The Netflix series 'Rafa' offers what is perhaps the most detailed public account yet of the sacrifices that lay beneath those 22 Grand Slam titles.
