I frequently experience canker sores, typically when my toothbrush accidentally grazes the inside of my mouth while brushing, or if I accidentally bite my cheeks or lips while eating. Recently, I've noticed a small sore with clear fluid inside. I have seen that this might be due to
vitamin deficiency, but I can't have vitamin supplements as I experience stomach disorders (stomach pain, loose motions, gas etc.) after having vitamin supplements. How can these sores be treated? Please guide.
