I thought was [improving] , really rough early last week it improved a bit around Thursday and has stayed the same since, give it another couple of days and try and get into to see doctor. I feel it is only upper respirity tract infection with no symptoms of anything else.
If you are snotty/phlegmy then perhaps you are right.
If you just feel awful and perhaps have a cough, obviously there is the possibility of Covid-19, unless I missed you saying you have been tested?
I should tell you that that my DVT/PE of 2012 started off like that though! I was convinced that I had a chest infection. I coughed so hard for a couple of weeks that I damaged my back/ribs. The first GP missed the cause of it and just assumed that it was a respiratory infection. It was actually clots in my pulmonary artery.
Even if you started off with a chest infection, being laid up for 9 days could trigger a DVT. When I was in hospital they gave everybody daily Heparin (anticoagulant) shots to guard against that.
I would not wait any longer to see your GP!
I hope you DO just have a minor infection and feel better soon!
