browen spot on side of tongue

I get frequent indigestiion and it seems i am allergic to many things that most people digest normally.  I had to eliminate any alcohol including wine or beer from my diet since 1962. I get palpitations from slight amounts of coffee or tea, even decaf, since age of 19.  I am now 76.  I have been diagnosed with Barrett's esophagus and inflamed esophagus since 2003 after every one of 4 endoscopies since..  PPD's do not work for me.  I ate out at a gala last night.  This morning I have brown ulcerations on sides of my tongue.  I frequently awaken with indigestion, sometimes nausea,  I had sour taste in mouth before i retired last night so kept drinking water.   Ate a slice of fresh pineapple to chase it and made some green tea but could not finish it due to digestive discomfort.  I took some more water  with 2 chamomile capsules and went to sleep.  My teeth felt chalky at 6 a.m. so brushed them with pink salt and rinsed my mouth which helped, but what are the brown ulcerations on sides of my tongue now?  is there a mild antidote?
