I've been frequently getting mild to bad sinus headaches over the course of about two and a half weeks. My eyes are abit irritated, and I am having alot of mucus build up in my throat. Whats odd is sometimes the pain is abit sharper and a little ways past where the Sinus headache pain has originated. I am also an Over-night worker two nights a week at a gas station, and was also wondering if this could adversely effect my sinus issues. Any advice is much appreciated.
