What is health anxiety and is it clogging up the NHS?

Latest figures show 73% of patients in England were seen within four hours in A&E last month - up from 71.1% in December - but still well below the NHS target of 95%. 
  
Doctors have told Sky News the winter crisis in the health service is being made worse by patients who are demanding urgent and immediate care when it is not always what they need. 
 
On the Sky News Daily, Niall is joined by health correspondent Ashish Joshi to discuss what is behind the rise in health anxiety and he also talks to Dr Adrian Boyle, president of the Royal College of Emergency Medicine, about how to improve A&E waiting times.
