I came down with something a couple of days ago. It started as difficulty swallowing and a headache but has morphed into a sore throat, cough and aches. I have had no fever (at least not according to my thermometer). I have not knowingly been in contact with anyone affected or who has been in an affected area. I am concerned that my chest has hurt throughout this period and I am exceptionally tired. Obviously I am self-isolating (don't want to go anywhere anyway!) and I know that I won't be tested but does this sound like coronavirus and, if so, is there anything else I should do?
