He also informed his fans that the first thing he said when he came round after his operation was: "did I win?"
Andy underwent a procedure to correct a problem he had with a disc in his lower back. It was the result of an injury he suffered before this year.
The complaint had caused him to pull out of the French Open in May, but he sufficiently recovered in time for Wimbledon - where he claimed victory to become the first male British singles champion since 1936.
He is likely to miss events for the rest of this year, meaning he will be absent from the ATP World Tour Finals at London's O2 indoor venue in November.
All being well he hopes to begin training for next season in November in Miami ahead of a return to the court for the Australian Open in January.
