Girls, hi. Constant mucus, phlegm from the throat into the mouth is coming out, there's a film on the tongue. I had this last year, then it got less, now it started again. We put in a rhinosinusitis and tonsillitis, gums bleed and there's some blood from the nose sometimes. Is it dangerous? I don't really believe about tonsillitis
