Tiger Woods says he will "never feel great again" following a long history of injuries and surgeries.
The 14-time major winner missed 15 months of action due to a debilitating back injury, which required two surgeries, while he has also had well-documented injuries to his left knee.
Upon his return, Woods missed the cut at the Farmers Insurance Open and shot a poor five-over-par 77 at the Dubai Desert Classic last week before withdrawing ahead of the second round having experienced back spasms.
And Woods admits the injuries and surgeries are taking their toll.
"I feel good, but not great," Woods said in an interview with former R&A chief executive Peter Dawson in Dubai.
"Granted, I don't think I'll ever feel great because it's three back surgeries, four knee operations.
"I am always going to be a little bit sore, it's just the way it is. But as long as I can function and function at a good enough level then I'm fine with that."
Woods added that he was unsure if he would be able to return to elite golf such was the severity of his trouble.
"It was more than brutal," he added. "There were times when I physically didn't know if I could get out of bed. And there were times I needed help just to get out of bed.
"It was one of the hardest things to wrap my head around, but I had a lot of great people around me to help me and keep my spirits up.
"There have been plenty of times when I thought I would never play the game [again] at the elite level. You put in the leg work, got to get in the gym, got to hit balls. You've got to refine your game and not make dumb mistakes out there on the golf course.
"In order to do that you've got to play a lot and I couldn't play. Playing once every three or four weeks is not going to cut it and there were a lot of times where I didn't think I was going to make it back."
