White stomatitis inside the mouth on 8/9 (Fri)... Is there a way to heal the inflammation quickly? (ToT)

Whenever I catch a cold or feel a little tired, I develop stomatitis. At first, it was small, but it gradually grew larger, and the pain worsened. It’s extremely painful when eating or brushing my teeth, especially since there is also inflammation in my gums, which makes me very concerned, and I even have a headache (；ＴДＴ).

It seems to last quite a long time even when applied.

I am currently applying OraMedy ointment. If there is a better ointment that can help faster healing of stomatitis, please recommend it.

These days, the weather is hot and I have more things to do, so I think I get more canker sores because I'm tired.

Mouth ulcers can also occur due to decreased immune function caused by fatigue, stress, nutritional deficiencies, etc. Fundamentally, boosting self-immunity is said to prevent the recurrence of mouth ulcers. Please recommend good supplements, health foods, or foods that help boost immunity (T0T).
