What Does Headache Along With Pain Behind The Eyes And Dizziness Indicate?

My name is Debra. I ve been taking care of my husband who has bronchitis. Been washing hands and using hand sanitizers constantly, sleeping in other bedroom, etc. But now I am starting to have symptoms, but slightly different. Headache, pain behind my eyes, frequent waves of severe giddiness/nausea/lightheadedness like I am about to black out. Dry non-productive cough. I feel chilled and hot back and forth, but no fever registers on thermometer. Rusty feeling in top of bronchial branch. Slight pain there when I take a deep breath. Fatigue, weakness. I am almost 62, just FYI.
