2 days ago, my tongue pushed out a lot of saliva which made me very uncomfortable. I have to swallow saliva all the time and it doesn't go away. I went to the pharmacy and they said I had acid reflux. I've been drinking for 2 days now and I don't feel any better, I always have a lot of saliva in my mouth. So the doctor asked me what is the cause of the excessive salivation in the mouth?
