Mistee, have you tried looking up oral lichen planus? I have that. It appeared at the same time as I was diagnosed Type 2, when I was under severe stress as a result of my 24th house move.
I don't know whether it can affect your tongue, but my symptoms were/are, linear thread-like things across the inside of my cheeks and little clusters of clear blisters, a bit like mouth ulcers. I still get a few of these, but they're not very painful now - they were very sore to begin with.
I believe it's an auto-immune condition, and unfortunately not really treatable, but there are some foods that trigger it -almonds, tomatoes, cheese in my case, but not so badly now that I can't eat them.
It may not be that at all, but it's worth looking up. I think many doctors aren't used to seeing it, therefore don't look for it, but mine got it straight away. At least you could discuss it, even if only to eliminate it.
