The OP mentioned needing to blow the nose and finding blood in it. Me too. I normally only need to blow my nose maybe once a week when I am well and it's usually dry, hard snot. (Sorry TMI?) Well with the virus I was blowing it several times a day but it wasn't runny at all, still dry amd hard. After blowing it the smell left in my nose and the taste in my mouth was kind of chemical. A bit like chlorine in the swimming pool, but not exactly like it. The dryness only affected my breathing. My digestive system stayed fine although I did have tummy cramps for about 4 hours in all. 4 weeks on from infection, yesterday in the garden, I sneezed. Oh joy! My nose was runny for the first time in 29 days. I can't tell you how amazing that was! You don't realise how moist your airways normally are when you are well until you have this virus.
