Do you think I have mono? I have been sick for a week now. It started out with nausea and a fever. Then I got a soar throat which was bright red and tight feeling. My fever came back with chills and body aches. I began to feel better but a severe pounding headache came along as well as a rash in my elbows. I have been incredibly tired and worn out throughout the Past few weeks but mostly the past few days. Now I have sores on the roof of my mouth and my ear hurts. I haven't been eating much either.
