When I tip my head, A very watery, yellowish, Liquid pours out of my nose , Its like a stream, It only comes out of my right nostril though. I was working in a section of my work that had me vacuuming cars, could this have been a allergic reaction to something in someones car. I did just get over a case of strep throat , Perhaps this is a sinus infection? Is this something that I need to get checked out?
