coincidences?

Scenario: Someone has a medical condition where early, mild, undiagnosed bouts of discomfort can eventually become immobilisingly painful attacks. While travelling abroad the sufferer becomes ill and has emergency surgery. The trip appears to be totally compromised. Despite innumerable potential problems of many kinds (not just medical) none actually occurs. Hospital care is first class and the whole procedure, lasting a few weeks, plays out without hitch and with an excellent outcome.

Becoming ill in that way, at that time, in that place, with such a good all-round result, was an amazingly complex set of coincidences. If everything had been planned to take advantage of the facilities on offer there, it could hardly have been planned any better! Was it really a set of lucky coincidences or might friends-in-spirit have orchestrated everything?

Could they have brought on the attack in order to take advantage of an advantageous situation? Would they need permission and, if so, how would that come about?
