There seems to be a virus going round. I have had similar symptoms and can't seem to shake it off. It has been about 3 weeks for me, I thought it was getting better, but it really has been worse for 4 or 5 days now, mine is a cough and really blocked nose, the rubbish that i am blowing into tissues is astonishing, it seems like every 10 minutes i'm blowing my nose, and that is no exageration! I've tried nasal sprays, couch mixture, lozenges etc, but nothing seems to help. I'm 71 btw.
