Lichen planus

Six months ago, I had a white line in my mouth, so I went to the dentist. They told me to go to a general hospital. So I went to Seoul National University Hospital, and after a biopsy, they said it was lichen planus.

The cause is still unknown, and there's no cure, but surprisingly, there are many patients like this. I've been taking medication prescribed by Seoul National University for six months, and while I've seen some improvement, I'm still uncomfortable. They say it can happen when your immune system is weakened. Stay healthy, everyone.
