Queen Elizabeth II worried royal fans again as Buckingham Palace delivered the news about her health condition.

Queen Elizabeth II braved all odds and appeared during the first event of her Platinum Jubilee celebrations, the Trooping the Colour. She stepped onto the Buckingham Palace balcony alongside the other members of the family.

She indeed showed high spirits, which seemingly hinted at her potential, continuous appearance amid her health issues.

But long before her appearance, the Buckingham had already clarified that her attendance throughout the weekend would only be confirmed on the day itself.

"The Queen greatly enjoyed today's Birthday Parade and Flypast but did experience some discomfort," a statement said.

Although she will still attend the beacon lighting on Thursday night, the Queen will be absent during Friday's main event, the Service of Thanksgiving, after sudden discomfort.

Buckingham Palace did not mention what discomfort the Queen exactly felt. But the central royal members are expected to represent the monarch once again.

The Guardian also noted that she probably experienced episodic mobility issues.

Queen Elizabeth II Had a Busy Day

The news did not shock some of the royal fans, though, as the Queen indeed had an exhausting day during the Trooping the Colour.

The monarch traveled from Windsor Castle to Buckingham Palace. Her health issues also led her to make Prince Charles take the salute instead.

Queen Elizabeth II also stood for a long time alongside the Duke of Kent and was seen leaning on a walking stick most of the time.

Following her appearance, several experts shared their opinions about the Queen and her health issues.

A royal writer and professor of marketing and consumer research at Royal Holloway, University of London, Pauline Maclaran, told Los Angeles Times (via Page Six) that many people have already been wondering what would happen after the Queen dies.

"We know who comes next in the line - Charles - even if of course many people want to see Prince William become king. But more than that, this family is going to hit a rocky patch. None of these men are as popular as the queen or as known globally," she said.

She noted that the monarch became frailer after losing Prince Philip and failing ill due to several health issues.

Still, Dickie Arbiter reminded everyone not to kill off Queen Elizabeth II as she has been known for being stoic and robust.
