I've been having a fever for about 3 days. I also have a runny nose and I can't breathe because it is blocked inside. Also i feel something whenever i eat ir drink or even swallow saliva on my throat. I kept drinking a Paracetamol Biogesic to cool down my fever but it doesn't work. I have headache too. But my vision is fine. I get cold easily so i need to cover myself with 4 layers of blankets. What should i take and do?
