I have found that the Mucinex brand of cold remedies is about the best you can find over the counter. It is a more expensive brand, but I find it worth every penny. If you have a hot water vaporizor could help with the sinuses, if not, run the shower on hot water only and let the bathroom steam up.
Rest up, have some of your favorite warm foods, soups, teas etc., maybe a good movie or a book and relax as best you can!
Hope you feel much better very soon!
