Junior doctors' planned series of strikes are an "unforgivable" betrayal of those needing care, the Patients Association has said.
Chief executive Katherine Murphy said it was a "disturbing" time to be an NHS patient as she warned medics may have gone a "step too far".
From a patient's point of view it is obviously catastrophic news - the scale of the industrial action is unforgivable.
It's putting patients under unnecessary stress and worry because every day they're hearing about a crisis in the NHS and the financial problems in our hospitals up and down the country.
She added that the public supported the medical profession but the extent of the strikes risked eroding public trust.
The medical regulator has urged junior doctors to seriously consider whether or not to take part in a new wave of strikes.
A five-day strike by junior doctors has been called in the ongoing dispute over contracts, but what does it mean for patients?
