Hello, I ve been suffering in the past 48 hours, with the following symptoms; fever, chills, headache, muscle/ joint ache, chest tightness (coughing up sputum ), diarrhoea, nausea, earache and fatigue . No sore throat . The onset was completely out of the blue. I have been taking Paracetemol to control my temperature, and aches. Is this sufficient? How long will these symptoms last please?
