Help! It started with a sore throat about 8 days ago then started getting worse. I have a terrible head cold that won't go away. I've had a very upset stomach as well and constant nausea. I'm having trouble eating anything and I can't taste anything either because of my sinuses. I've never been sick for 8 days straight and I feel. like I'm not getting better. Any tips? Or has anyone else experienced flu like symptoms?
