I saw my dentist today  who said he has never seen lumps like the ones I have at the back of my tounge.  They are not red or painful, just raised.  I do have acid reflux and take prilosec daily.  I have had a lap band for 5 years and have had 2 endoscopies in the past 6 months.  I have a bitter tast in my mouth that never goes away.I am 50 years old.and am in menopause.
