Follow-Up:
I've got what you've got. I tried vitamin B12, iron, zinc, cortisome, ferrous folic something, but nothing works. I've had blood tests done too. I also talked to my doc about glossitis. He said that's a rough tongue complaint no what I've got. Dentist checked my teeth. Food irritates, apple juice seems to help but then cold stuff does. I try to keep something in my mouth all the time. It's noted that if your brain is sent a message to taste food, it can't think about pain also. That's why eating seems to make the pain go away. I have a good article from a professor you should read.
