"Here's how it goes," White explained. "I'm scared (going) to the airport, I'm scared going up, I'm uncomfortable in the air and I feel like a million bucks when we hit the runway."
White was also absent from the Rockets' media day on Monday. The team made the short flight to McAllen later that day, and White started tweeting about his discussions with the team on Wednesday night.
"There is nothing but very positive strides being taken right now between I and the Houston Rockets to support health," he wrote. "This innovative plan is being well thought out by both parties, when it's done I think an executable plan will be there...A Healthy plan."
White added that "my health now is great, the best its ever been." He said "the long term is the goal here."
The Rockets and White did not give a timetable for his return. Houston plays its first preseason game next Wednesday night, against Oklahoma City in McAllen.
