Hello, my symptoms are as follows, Dry Mouth(especially early in the morning) but definitely producing significantly less saliva than usual, maybe 40 to 50 percent less for last 6 weeks. White Coating on tongue, not sure whether it is thrush or not for 5 weeks. Ranula cyst on floor of the mouth. And palpable tender submandibular on right side of jaw. Have been under immense amount of stress and anxiety since middle of october and symptoms are freaking me out, please advise.
