About a week ago I started to developed a yellow tongue with a funny taste (sick taste and a bit sour) and I don't have bad breath thought.
My diet is still the same, I've been smoking for years now and I do brush my tongue as well. Some days the yellow color is lighter than other days but is still there? I've starte to use some whitening mouthwash (Colgate) and that's the only change I've made that I can think of. For about 3 days now I haven't used the mouthwash and my tongue is still yellow and still have the funny taste. I do have sinus problems thought but not 2 bad and lately my nose is a bit blocked and have the post nasal drip.
What do you think could this possibly be?
