I'm feeling really worried because I've had symptoms like a fever around 100F, a lot of coughing, and this weird pressure on the left side of my chest and back for the last four days. I've stayed at home, isolated myself, and took a COVID test, but I don't have the results yet. I also have asthma and allergies to dust and smoke. Could you please suggest what precautions to take and if there's any medication I should consider?
