The reason people lose their sense of taste and smell is probably because with this virus being akin to influenza it affects the sinuses.
Pudding123, by the second week I thought I'd had it because I had a pain in my back and my chest felt as though someone was sitting on it, then both legs " seized " up and I couldn't move them properly. I knew this was part of a chest infection as my body began to ache all over, even my fingers ached !
The cough was something else. That lasted a week. All this began on 29th of December and I didn't feel human until well into February. I didn't inform the GP or anyone, just took paracetamol, honey, rum in hot water and hoped for the best.
