Hillary Clinton has said in a telephone interview that she is feeling "so much better", a day after being taken ill at a 9/11 commemoration.

She also said she had not disclosed a recent pneumonia diagnosis because "I just didn't think it was going to be that big a deal", reports the BBC.

The US presidential candidate said she had ignored a doctor's "wise" advice to rest for five days.

Her rival Donald Trump said health had now become "an issue" in the campaign.

Hillary Clinton said during the phone interview that she hoped to be back on the trail in "the next couple of days".

The Democratic White House nominee acknowledged she had lost her balance during Sunday morning's health scare, but said she did not faint.

"I felt dizzy and I did lose my balance for a minute, but once I got in (the van), once I could sit down, once I could cool off, once I had some water, I immediately started feeling better," she said.
