His Majesty the King is no longer feeling pain in his right knee but his left knee remains sore, the Royal Household said in a statement released on Monday night.
A team of royal physicians at Siriraj Hospital said the King felt slight pain in his left knee when he moved, and doctors continue to provide him with medication to treat the swelling.
His Majesty's heartbeat and blood pressure remain normal, but he still has a low fever and feels tired, the statement said.
The King has a good appetite and is sleeping well.
