I have been sick 3 days now. First day had a sore throat and stuffy nose and it continued during the day into fever and chills, no appetite, and weak, slept most of the day. Day 2 the sore throat was gone but congestion remained, had a headache, ears were plugged, still fatigued and weak, no appetite, ate soup but had a coughing attack and puked. Day 3 felt like I could drink water and had cup of tea. Still feel weak and no appetite. Ate some yogurt but then had diarrhea bit after. Still feel hot and cold but no actual fever. Have looked up symptons for mono because have been around family friend that now has it but I don t have symptons except tired and weak. And I m a 36 yr old female. Any ideas? Had husband look with flashlight at mouth/throat. He said a couple of red dots on roof of mouth but no white spots and nothing on throat.
