Geographic tongue pain

OK so Ive had geographic tongue since I was about 12. I’m in my early 20s now, and would like to hear other people’s experiences with geographic tongue, especially in regards to the pain factor. Ive been told most people don’t experience pain with it.
I used to get the pain under my tongue near my tongue web, this went away after a while
Now, I get pain on the side of my tongue
This occurs mostly after I drink alcohol or eat spicy or sour foods. Is there any way to stop this pain? Apart from avoiding these types of foods of course.
Side note: I am anaemic and have a B12 deficiency and take supplements for this (I believe this is part of the reason I suffer from painful symptoms)
