It is called oral burning sensation syndrome.

I had intermittent tongue pain for a long time, but I just ignored it and left it alone for about ten years.

There were times when I couldn't tell the difference between Gan Jjamppong and Jjapaghetti even if I ate them with my eyes closed.

The sweetness of the candy fluctuates randomly up and down.

I went for a health check-up and thought I might have an allergy, so I also had tests done.

Then I went to a university hospital and was diagnosed with Burning Mouth Syndrome.

I was told to stop taking vitamins after my vitamin B levels more than doubled, and I took medication for four months to bring it back to normal.

I have been trying different medications since then, but there has been no improvement.

Is this really happening during the day?
