Have small traces of blood in saliva, mostly in the mornings. Saw ENT, but all he could see was a small irritation in throat. Prescribed nasil spray, "magic mouthwash" and Pevasid. All didn't help. Went back to ENT, scoped me again and suggested Singulair for allergies. Again, didn't help. Lastly, once in a while I spit up what I think are "pee" sized tonsil stones....food particles. Any ideas?
