Bradman's diagnosis for appendicitis came after the conclusion of the tour.
For some considerable time before the voyage out from Australia, Bradman felt very unwell and was in some doubt as to whether he was well enough to go on the tour. Therefore at his own expense, Bradman went to the leading physician in Adelaide to ask if he could find anything wrong. Nothing was found, but the physician did say that Bradman was very run down and badly in need of a rest. Although he agreed that Bradman was well enough to go on the tour, he didn't wish the great batsman to play any matches at all until he got to England.
On arrival at England, Bradman was still very unwell, suffering regular migranes and lameness, but as no one could find anything wrong, he played. His form suffered early in the tour, with just two centuries and 952 runs at 52.94 by July 13th, a disastrous return by his meteoric standards. However, Bradman's health seemed to improve for a time when he found his form in the Fourth Test, scoring a triple century, again at Leeds, and with Bill Ponsford putting on 388 in a record fourth wicket partnership. In the Fifth Test, Bradman made 244 and Ponsford 266, their partnership of 451 was the highest ever made in Test cricket. Seemingly restored to full health and tip top form, Bradman hammered two more centuries in the final two games of the tour.
However, upon returning to London to prepare for the voyage back to Australia, he experienced severe abdominal pain. It took more than 24 hours of detailed scrutiny and observation for the doctors to diagnose acute appendicitis and a surgeon had little choice but to operate immediately. Unfortunately, the four hour operation caused serious complications and his condition worsened into peritonitis, which in those days, with penicillin and modern antibiotics still a long way off, regularly proved fatal. On 25 September, the hospital issued a statement that Bradman was struggling for his life.
Bradman's wife Jessie started a month-long journey to London as soon as she received the precarious news. While en route, in Melbourne, she heard a rumour that her husband had died. However, she was a woman with a rather optimistic view of life and refused to believe it, but decided to ring the hospital to confirm. Of course he wasn't dead so she continued her voyage. By the time she reached London, Bradman had begun the slow road to recovery, but was still very weak. He followed medical advice to convalesce, and upon returning to Australia took several months rest at his wife's father's farm in New South Wales, and he missed the entire 1934–35 season in addition to a tour of South Africa which did not take place until nearly 12 months afterwards.
