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.
Chills and headache can be due to the sinusitis. I recommend starting an antibiotic like Amoxicillin, water vapor inhalation, and warm saline gargles to relieve throat inflammation and sinuses. If the symptoms do not improve, then I would recommend a visit to a doctor and get some blood investigations done. A complete blood count, X-ray of facial sinuses can help in diagnosis and starting treatment. Hope this answers your question, thank you.
