I have black hairy tongue but I also have sores in my mouth and nothing I eat tastes right. THe doctor who identifies b.h.t. said I had throat and voice box reflux and gave me
Prevacid. Is there another condition I could have with bht and how can I stop the reflux in my stomach? could I have oral herpes?
