The Palace declined to comment when asked about her condition.
That didn’t stop royal watchers from speculating on social media, Fox News reports.
“I love keeping up with Queen EliAbeth (sic) II but I’m concerned. Why does she have such a terrible bruise on her left hand. Did I miss something? But as always, she looks stunning!” one Twitter user wrote.
Another tweeted: “The lady is 92 at that age any little knock unfortunately (sic) turns into what can look severe bruises. The Queen is rather fab though isn’t she???”
“Did the Queen have a fall? What is wrong with her hands? I am concerned for her,” another fan pointed out.
