Ever since then-Prince Charles joked about his "sausage fingers" back in 2012, after getting off a long haul flight to Australia, many have wondered what is the cause of the monarch's swollen hands.
While King Charles III, who was coronated on Saturday at Westminster Abbey, has never directly addressed the reason, many royal fans have speculated, especially after seeing him pour a pint during a royal engagement in 2021.
At the time, one fan took to Twitter to say: "I've never noticed the hands of Prince Charles until this photo. Is he okay? They are so swollen."
