Tongue Bald spots

[notwell123]

I have a recurrent spot on the front left portion of my tongue.  It starts off with the papillae being a little rough, within a day or so of that, they start to disappear.  The spot then grows over the next couple days, it's ovalish, no heavily defined border.  No pain, bleeding, discharge or anything like that.  Sometimes there's moderate sensitivity to hot beverages and within a week, weak and a half, the papillae start to grow back in and the spot completely disappears.  This comes back again in 1.5-2 months.  Any idea what it could be?

Do you have any other symptoms like skin problems, digestive symptoms, nail changes, anything?

I get some breakouts here and there, I have had a few more intense pimples behind my ears and around hairline than normal I guess.  Nails seem fine , digestive track is good I think. I had some minor headaches come and go for a few months and shaky legs on occasion.
