Hello Dr. Rynne,My husband, 49, has had flu like symptoms for about three weeks now. All he wants to do is sleep, gets chilled easily, frequent headaches, and a heavy chest congestion. He has described weak knees. He has never been this sick before. The first week he had fever, but it seems have gone away. His appetite is poor. Monday, I plan to take him to the doctor or urgent care, as he has refused to go. Any thoughts .. Julia
