It had to happen with some of the amazing steps being made in mobile phone technology.

But now NHS Direct has launched a new free iPhone and Andoid app which basically allows you to diagnose various ailments and illnesses.

The app includes access to 37 health and symptom checkers covering a wide range of problems including dental pain, diarrhoea and vomiting, abdominal pain, rashes, back pain and burns.

It is linked to NHS Direct's telephone service and, if a further assessment is recommended, users will be able to submit their contact details so that an NHS Direct nurse advisor can call them back.
