Doctors have ended their strike and returned to work amid new hope that a deal over changes to their contracts can be reached before the next planned 48-hour walkout.
Thousands of junior doctors walked out for 24 hours, while around 4,000 operations had to be cancelled.
Two further strikes are planned but talks are expected to resume in an effort to break the stalemate.
Widespread support for the junior doctors' strike among senior health colleagues may lie in the fear of what could still be in store, ITV News political editor Robert Peston has said.
Junior doctors in England took to the picket lines on Tuesday over proposed changes to their contracts as part of government plans for a 'seven-day NHS'.
But Peston pointed out a seven-day NHS would not stop with junior doctors - it would require the rewriting of many more contracts across the health service.
He said the government was banking on doctors not wanting to launch the "nuclear option" of strikes which affect emergency care - but warned the two sides were playing a "very dangerous game of brinkmanship".
Health Secretary Jeremy Hunt wants to extend normal working hours to include Saturdays - with a pay rise supposed to balance out the loss of extra weekend allowance - as part of the government's bid to tackle increased mortality rates at the weekend.
Retired Dr Henry Goodall, who was a junior doctor in 1970, says the current generation are "used to working less hard with fewer hours".
As junior doctors in hospitals across England go on strike for 24 hours today, a junior doctor writes for ITV News on why she is striking.
A government aide was filmed trying to prevent a reporter asking why Jeremy Hunt was not speaking ahead of today's national doctors' strike
