I Have Been Suffering With Raised Taste Buds On The

I have been suffering with raised taste buds on the back of my tongue for 4 years. I have had 2 endoscopies that proved to be normal. I was finally diagnosed with urticaria(hives) but was told that it would be impossible to find out what I was allergi9c to. My family doctor says that it is severe acid reflux disease that could lead to Barretts esophagus(God forbid). What are your thoughts on this.
