KOHLER, Wisconsin (Reuters) - World number two Phil Mickelson has been diagnosed with psoriatic arthritis but says he feels 90 percent fit ahead of this week's U.S. PGA Championship at Whistling Straits.
The American left-hander experienced intense pain in his joints shortly before the U.S. Open in June, making it difficult for him to walk.
Since consulting with specialists, however, he quickly began to recover after starting treatment and taking medication.
"Things have been looking great and long term there shouldn't be any issues," Mickelson told reporters on Tuesday.
"It's very treatable and the medicine I've been taking has been very helpful. I feel 90 percent."
