(Concern) Do you frequently get canker sores?

When I was young, I often got canker sores on my tongue, and it was painful.

Especially, they say that the tongue and inside of the mouth are the most sensitive.

There are limits to taking anti-inflammatory drugs and antibiotics, and Albochil is only effective for a while.

It’s so painful to have to rest for 3-4 days for it to go awayㅠㅠㅠ

Is there a special remedy for mouth ulcers?
