Meg get a bowl of boiling water, and put a few drops of eucaluptus(sp ) oil in it or if you have none just salt and put a towel over your head and breathe in for about 5 mins or more, do this twice to three times daily, it will help those sinuses, being a fellow sufferer I use this method and it is recommended by the doctors., better than using nasal sprays etc, which end up blocking you up more in the long run, and can only be used for a short time.
