I have almost uncontrollable strong shaking with chills in the late afternoon and early evening. Accompanying this is a headache (moderate, 1 to 3 hours), nasal congestion, Chest congestion, coughing and sore throat. When I get into bed fully clothed, under 2 or 3 blankets the shaking eventually stops and I begin to feel very hot and must get out of the bed. This has been going on for two days. This has happened before with cold symptoms, but not this strongly. I am a diabetic fairly controlled and I have an Aortic valve problem. Unless I am sitting and have my arms tightly wrapped around my chest. The shacking can leave me panying for air. I am 66.
