Bolt was suffering from a hamstring problem six weeks ago as he lost the Jamaican Olympic trials over 100m and 200m to training partner Yohan Blake.
He visited Wilhelm Müller-Wohlfahrt's clinic in Munich for advice and treatment.
"He's a major part of my success in my career," said Bolt. "I've been going to him since I was 18 or 19. Since I first started, he's really done great work on me. After the trials he looked at my muscles, did his treatment and said: 'Don't worry, Usain. You're going to do great. Just go back and train.'"
"He's the best doctor in the world. The doctor is a great, great man.
"He's more than a doctor. He takes me to dinner, looks after me, comes in on weekends to treat me and make sure I'm okay. I thank him for all he has done for me."
Bayern have their own injury problems to deal with. Mario Gomez, Diego Contento, David Alaba and Rafinha are out for several weeks but Bastian Schweinsteiger, Franck Ribery and Claudio Pizarro should be ready for the start of the season.
