For the past couple months ive been experiencing post nasal drip/excessive mucus production and a white tongue. Ive been trying to link it to an std because thats the only event i can think of to get me sick, but with negative results for gon, clym, syphilis, herpes, hepc, and hiv, im begining to think there isn't a connection between the two. Ill wake up and my nose will be clogged. Ill blow it just to have to try and and suck it back and try to swallow it. Then instead of having a clogged nose all day, its dripping back and im constantly swallowing it down. My tongue is white for reasons i dont know i cant fogure it out its white and has some raised bumps towards the back of it. Please any insight would be great.
