So Ds (17) has had a cold since mid December. It is running the normal course all be it slowly. Had temp and sore throat, then the runny nose and cough. Just as he began to think he was getting over it he now has painful face and headache again. He clearly has gunk still in his sinus.
Now, not only is he now thoroughly fed up with it all but he has mock a levels in January and needs to be able to do plenty of revision. So before I go and buy half of boots, what are the best medicinal or home remedies which will help clear it? Thanks
