Anyone any cures for mouth ulcers? I have about 3 on the tip of my tongue, and then big ones on the sides of my tongue, 4 under my tongue and 2 clusters on my lower lip - inside. Kept waking me up in the night it's stinging so much. I've been putting bonjela on them, and doing a corsydol mouthwash, but in agony. At work all day today and I cant talk properly! TIA
