I have ulcers all over my tongue. My doctor told me it will go away in about two weeks, and no real cause has been found, though it is suspected to be a virus. Because of this condition (tongue is in pain and overly sensitive), saliva has been building up in my mouth too much, so I swallowed them whenever it fills up my mouth, but I feel kind of nauseous now. Is this because I m swallowing too much saliva? Can swallowing too much saliva be bad for you?
