Mike Tyson reveals ‘really bad’ health issue that’s plagued him for decades

Mike Tyson said he has a “disintegrating dose” of foot fungus and his toes “look like they blew up.”

During a Tuesday appearance on “Jimmy Kimmel Live,” the former heavyweight champion explained that his fungus “is still really bad” while discussing why he never wore socks in the ring as he rose to the top of the sport in the 80s.

“I only used to for fighting where that was my image,” Tyson, 59, said. “It was real hardcore, no socks.

“And then I somehow discovered that I had a disintegrating dose of foot fungus. And it was really bad. It’s still really bad now. I got it fixed. Come on, I’m serious, man.”

When asked by host Jimmy Kimmel if “foot fungus is your greatest opponent of all,” Tyson agreed.

“Well, I would have to say so because it’s still kicking my ass now,” Tyson said.

Kimmel joked that Tyson would be great in a commercial for Desenex, an anti-fungal foot powder used to treat athlete’s foot.

“Desenex cannot help me,” Tyson said. “My toes look like they blew up.”

Tyson and Floyd Mayweather agreed to an exhibition fight in 2026.

Tyson last fought Jake Paul in November 2024.

The internet personality-turned boxer defeated Tyson by unanimous decision in an eight-round heavyweight bout at AT&T Stadium in Arlington, Texas.

Tyson dealt with a number of health issues leading up to the fight, including an ulcer flare-up, which forced them to postpone the fight.

After the fight, Tyson revealed he almost died in June 2024.

“This is one of those situations when you lost but still won,” he wrote on X. “I’m grateful for last night. No regrets to get in ring one last time. I almost died in June.

“Had 8 blood transfusions. Lost half my blood and 25lbs in hospital and had to fight to get healthy to fight so I won. To have my children see me stand toe to toe and finish 8 rounds with a talented fighter half my age in front of a packed Dallas Cowboy stadium is an experience that no man has the right to ask for. Thank you.”
