Wrong. You're thinking of cold sores.

I suggest a gluten-free diet.

In my Merck Manual (16th edition) it says "Etiology is unknown, but several
factors point toward a localized immune reaction. Deficiencies of iron,
vitamin B12 and folic acid increase susceptibility. Stress and local trauma
are usually the predominant precipitating factors."

I have several articles connecting canker sores (same as apthus ulcers)
with gluten consumption, even in people that are not celiac. They are a bit
long to post, so instead I have put them at my web site. Here they are:
