The Queen, 95, had previously been advised to step back from duties.
Her personal doctors advised her to rest which caused Her Majesty to miss the Remembrance Sunday ceremony last week.
It was reported Her majesty had sprained her back and has carried out only light duties since her hospital stay on October 20.
The Queen also marked her first wedding anniversary since her husband died in April on Saturday.
It would’ve been the pair’s 74th wedding anniversary.
