Around that same time, I noticed that my snot suddenly changed from generally clear or milky in color to bright, highlighter
yellow. It all appears to be from just my left nostril, and while most of it is thick, after I blow for a little bit, the thick stuff turns to a very runny, very yellow fluid that feels almost like a bloody nose dripping out of my sinuses. Sometimes, the color is just a normal, milky yellow, but most of the time it is very dark, and often almost orange.
