All week since about last Sunday my chest has been tight, with some back pain, Developed a snotty nose on the Friday just gone , followed by hot flushes, sore throat, lethargy, loss of appetite on Saturday, cough on Sunday with loss of smell and taste, still with sore throat but the chest pain has gone then today I'm still snotty, coughing terrible, literally exhausted and still hot.
I had a COVID-19 test Sunday and got a negative result today.
Has anyone else had what I have had and if so what is it? I've never had a cold this severe lack literally wiped out. It feels like a cold but worse 
Had anyone else had this and how long did it last?
