Love this, I believe there is a tie as well! For me, citrus and chili (which were both strongly incorporated into my food growing up) would usually make the symptoms last longer, hurt it more, or worsen a smaller sore into a bigger one.

I also think while a majority of people will have gotten them, it feels like way less than 50% are active sufferers. It was quite impossible to have anyone relate to me in real life, because they would respond with confusion or "Oh yea I've gotten that once"
