Bryson DeChambeau underwent surgery in December to alleviate an issue that caused his vertigo, he revealed in an interview with the LIV Golf website posted on Wednesday.
DeChambeau had surgery on December 15 to remove a retention cyst in his left maxillary sinus. That issue led to dizzy spells and bouts of vertigo that have plagued DeChambeau since the 2020 Masters.
"To get that fixed, it's been the greatest decision of my life," DeChambeau told the website. "My energy level is so much better. My clarity of thought is way better. I don't know if you can tell, but my speech is a lot more fluent and I'm not stopping as much or pitching as much like I used to last year and before.
"I feel like I'm back to 2018 me."
For DeChambeau, 2018 was a successful year on the golf course.
He burst onto the scene by winning four times that year, raising his rank from 99th to fifth. As for 2022, that was a "reset year" for DeChambeau.
DeChambeau, 29, dealt with wrist surgery, significant weight loss and the loss of his father, Jon, after a near-three-decade-long battle with diabetes. On the golf course, the 2020 US Open winner did not record a victory during the 2022 calendar year.
DeChambeau also admitted that he is no longer aggressively chasing distance with his shots.
"Technology is not up to par with the way golfers can perform at high speeds," he told the website. "Anything over 185 mph - good luck trying to control it right now. We're still on a pursuit to who can make a driver that can work it at 200 (mph) anywhere and everywhere on the face and still goes in the fairway. When that day comes, that's going to be eye-opening for a lot of individuals ... and it's going to change the game forever. But we're not there yet."
