After 6 yrs I told my doctor at Mayo- Dr. C Loftus about my mouth and tongue. ( I thought I was imagining it , since occurred after ostomies) . But he wants to do blood work and said they have a burning mouth clinic at Mayo. I also have had growth of bone out in my gum line and dentist “ poo. Poos” it .And cannot drink out of any plastic without exacerbating burning mouth.
